The Cisco AS5800 universal access servers support universal port carrier cards, and DMM modem cards. For details on these modem carrier cards, refer to the Cisco AS5800 Universal Access Server Hardware Installation Guide and Cisco AS5800 Universal Access Server Dial Shelf Card Guide. The universal port card (UPC) supports NextPort hardware and software interfaces. A port is defined as the binding of a TDM channel, service, and data queue to support a bidirectional service on the UPC. A universal port is a port on a UPC that can be switched freely between two or more services without changing the TDM channel.
You can manage port connections at the UPC, service proccessing element (SPEthe processor on the slot card that executes protocols to process in-band data) or port level using monitoring, polling, and troubleshooting commands. NextPort management functions are very similar to MICA modem (DMM) management functions. This document discusses procedures and commands similar in both types of services and procedures, and some unique to the NextPort architecture.
NextPort introduces shelf, slot, and SPE software hierarchies. On the Cisco AS5800, the hierarchy is shelf/slot/spe. The user can perform the following functions on an SPE:
This document includes the following sections:
By default, event logging is enabled, and SPEs are polled every 12 sec. The log contains raw data in binary form, which must be viewed using the show commands listed in the "Viewing Statistics" section.You may configure some aspects of how the record is kept using the following global configuration mode commands [at the AS5800(config)#
prompt]:
The following Enable Mode (also called Privileged EXEC Mode) commands allow you to clear some or all of the log events relating to the SPEs (at the AS5800#
prompt):
You can view SPE statistics using the Cisco IOS software with the Cisco AS5800. To view performance statistics for the UPCs, enter one or more of the following commands in Enable Mode (also called Privileged EXEC Mode), at the AS5800#
prompt:
This section describes how to manage NextPort ports by clearing ports, entering port configuration mode, removing ports from service, and disabling ports from dial-up service. For details on disabling a port from dial-up services, see the section, "Troubleshooting" .
Ports may need to be cleared if polling attempts have failed and the port is removed from operation.This is done using the clear port command.
Use the show spe shelf/slot/spe command to view the active ports on an SPE. To clear ports on an SPE, enter the following command in Enable Mode (also called Privileged EXEC Mode). The user can clear all ports on the NAS, all ports on a slot, or a port. This replaces the clear modem command.
Port configuration mode allows the user to enter a mode similar to the line configuration mode. This mode allows individual ports or ranges of ports to be shut down or put in busyout mode. Port configuration mode commands replace the modem range, modem busyout, and modem shutdown commands used with MICA modems.
The following commands are available in port configuration mode:
This section describes how to manage SPEs by setting the SPE country code, clearing the SPEs, entering SPE configuration mode, upgrading the SPE firmware, and performing busyout on SPEs.
Enter this global configuration mode command to specify the country to set the UPC parameters (including country code and encoding) for UPCs. The default is usa if the access server is configured with T1 interfaces and e1-default if the access server has E1 interfaces. Use the no form of this command to set the country code to the default of domestic.
Note All sessions on all slot cards in all slots must be IDLE (no calls are active) for this command to execute. |
A list of all supported countries is displayed in the help file. This replaces the modem country command.
SPE configuration mode allows the user to enter the SPE configuration mode, which is similar to the line configuration mode. The user can configure an SPE by specifying a slot and an SPE associated with the slot or, the user can choose to configure a range of SPEs by specifying the first & last SPE in the range.
The following commands are available in SPE configuration mode:
This section describes how to perform diagnostic testing on installed ports or SPEs, test two ports back-to-back, disable ports from service, and recover a port that is frozen.
To perform self-diagnostic testing on all the installed ports during the system's initial startup or rebooting process, or during service, enter the following command in global configuration mode [the prompt is displayed as AS5800(config)#
]:
The results of the SPE self test are displayed in the Status column of the output from the show spe modem and show spe modem active commands. Ports that pass the diagnostic test are marked as Idle, Busy, Downloading, and Reset, and are put into service. Ports that fail the diagnostic test are marked as Bad, and are not put into service or tested again until they are no longer marked as Bad. If all the ports of an SPE are bad, the corresponding SPE is also marked bad. These ports cannot be used for call connections. Depending on how many ports are present and not marked Bad, this diagnostic test may take from 5 to 15 minutes to complete. You may perform additional testing on an inoperative port by executing the test modem back-to-back command. The no port modem autotest command disables testing.
You may additionally configure the following options:
When a port has tested as being Bad, you may perform additional testing by conducting a series of internal back-to-back connections and data transfers between two ports. All port test connections occur inside the access server. For example, if mobile users cannot dial into port 1/2/5 (which is the sixth port on the UPC in the second chassis slot oof shelf 1), attempt a back-to-back test with port 1/2/5 and a known-functioning port such as port 1/2/6.
Enter the following command in enable mode (the prompt is displayed as 5800#
) to perform internal back-to-back port tests between two ports:
You might need to enable this command on several different combinations of ports to determine which one is not functioning properly. A pair of operable ports successfully connect and complete transmitting data in both directions. An operable port and an inoperable port do not successfully connect with each other.
A sample back-to-back test might look like the following:
If you attempt a back to back test on a port that is in use, the output will resemble the following example:
A port that has been confirmed to have problems can often be fixed using the clear spe command. For more information, see the "Clear an SPE" section.
To disable ports from dialing or answering calls, enter one of the following commands in port configuration mode [the prompt is displayed as AS5800(config-port)#
]:
The busyout command is not executed until the active port is idle. No active connections are interrupted when you use this command. In contrast, the shutdown command immediately terminates all active connections on the specified port. The resulting port status for both these commands is the same. Enable the no form of these commands to restore a port for dial-up services.
You can still configure the following commands on a disabled port:
You may also disable ports on specified SPEs in SPE configuration mode [the prompt is displayed as AS5800(config-SPE)#
]. Some problems with ports require a reload of SPE firmware, and all ports on an SPE will need to be out of service to reload the firmware.
Configure automatic recovery (removal from service and reloading of SPE firmware) of ports on an SPE at any available time from global configuration mode as shown [the prompt is displayed as 5800(config)#
]:
When an SPE port fails to connect for a certain number of consecutive times, it indicates that a problem exists in a specific part or the whole of SPE/firmware. Such SPEs have to be recovered by downloading firmware. Any port failing to connect num-failures times will be moved to a state based on port-action, where you can choose to disable (mark the port as Bad) or recover the port when the SPE is in IDLE and has no active calls. The default for num-failures is 30.
You may also schedule recovery using the spe download maintenance configuration command.
Configure a scheduled recovery of SPEs from global configuration mode as shown [the prompt is displayed as 5800(config)#
]:
Download maintenance starts at time, steps through all the SPEs that need recovery and SPEs that need a firmware upgrade and starts maintenance on max-spes at a time. It waits for the window delay time for all the ports on the SPE to become inactive before moving the SPE to the Idle state. It will download firmware immediately after the SPE moves to idle. If the ports are still in use by the end of (window), depending on the expired-window setting, the port marked for recovery can be set to be moved to the disabled state by choosing the disable option, connections on the SPE ports will be shutdown and the firmware will downloaded by choosing the drop-call option, or the firmware download is rescheduled to the next download maintenance time by choosing the reschedule option. This process continues until the number of SPEs under maintenance are below max-spes, or until stop-time (if set), or until all SPEs marked for recovery or upgrade have had their firmware reloaded.
The clear spe Enable Mode (also called Privileged EXEC Mode) command allows the user to manually recover a port that is frozen in a suspended state. This command causes the firmware configured for that SPE to be downloaded to the specified SPE or the range of SPEs and Power on Self Test (POST) to be executed. This command can be executed regardless of the state of the SPEs. All active ports running on the SPE are prematurely terminated and messages are logged into the appropriate log. This replaces the clear modem command.
The following example shows a coldstart on SPE 1 on slot 1.
Cisco IOS Release 12.1(2)XD or later is required for using UPCs on the Cisco AS5800. Matching Cisco IOS images are needed for both the router shelf and the dial shelf. The required images should have been shipped with your UPC, and the Cisco IOS software may be upgraded using the same instructions as are used for upgrading unbundled firmware files.
At startup, UPCs copy a Cisco IOS software-compatible version of SPE firmware to the installed SPEs. By default, the SPE firmware version bundled with the current version of the Cisco IOS is loaded, but the SPEs may be configured to use unbundled SPE firmware files.
Note You do not have to take any action to use the pre-installed version of SPE firmware with new systems using Cisco IOS Release 12.1(2)XD or later. |
You can acquire new SPE firmware in several ways:
After you have the new firmware, you can configure different firmware versions onto individual SPEs or ranges of SPEs on a UPC. You can also configure different upgrade methods.
This section describes how to upgrade SPE firmware handling your access server ports by:
1. Understanding the SPE firmware scenarios possible for your access server.
2. Choosing an upgrade strategy.
3. Finding out the SPE firmware version installed on your access server.
4. Upgrading the SPE firmware.
You can obtain SPE firmware in one of two ways:
There are several commands you use to upgrade SPE firmware. For examples on using the commands, see "Upgrading SPE Firmware from the Cisco CCO TFTP Server," "Upgrading SPE Firmware from Diskettes," and "Using the SPE Firmware Bundled with Cisco IOS Software".
Note The copy ios-bundled command is not necessary with UPCs. By default, the version of SPE firmware bundled with the Cisco IOS software release transfers to all SPEs not specifically configured for a different SPE firmware file. |
Because of multiple versions of SPE firmware and the way Cisco IOS software processes these versions, Cisco suggests that you choose one of the following two strategies:
To help with the decision, Figure 3 shows a hypothetical release process. Using the SPE firmware bundled with Cisco IOS software is the easier strategy and enables you to take advantage of new SPE firmware whenever you upgrade your Cisco IOS software. You can control the SPE firmware by using the copy command as discussed later.
Table 5 provides scenarios that can occur when you upgrade Cisco IOS software or SPE firmware.
Table 5 Cisco IOS and SPE firmware upgrade scenarios
Scenario | Update Process | |
---|---|---|
Step 1 | ||
Step 2 | You update Cisco IOS software, and you decide to use the version of SPE firmware selected by Cisco IOS software. |
|
Step 3 | You update Cisco IOS software, and you decide not to use the SPE firmware selected by Cisco IOS software. |
|
Step 4 | The SPEs are running a version of SPE firmware from system Flash memory that is different than the version bundled with Cisco IOS software. You decide to revert to the bundled version. |
|
Step 5 | Cisco releases new SPE firmware, which is a later version than the version currently running on the SPEs. You decide to use Cisco's newest SPE firmware.4 |
|
1To find out the version of SPE firmware in your system, use the show spe version command. This command displays the versions running on the SPEs.
2In part, Cisco IOS software bases this decision on the last copy command issued. 3The copy ios-bundled command is not necessary with UPCs. By default, the version of SPE firmware bundled with the Cisco IOS software release transfers to all SPEs not specifically configured for a different SPE firmware file. 4Cisco might ship this SPE firmware on a diskette packed with the spare carrier card. |
Figure 4 shows a location on the release timeline where updates might take place, and Table 6 explains the resulting versions of Cisco IOS software and SPE firmware.
Table 6 Cisco IOS and SPE firmware results
1This example assumes the last copy command was copy flash modem, and SPE firmware Version 1 was specified. |
Use the show spe version command to list the versions of SPE firmware running on the SPEs, residing in system Flash memory, and bundled with Cisco IOS software. This will help you decide if you need to change the version running on the modems.
The following example shows an example of the show SPE command for a system with one 324 universal port card.
Upgrading SPE firmware from the Cisco CCO TFTP server is a two-step process:
Note Cisco IOS software contains bundled SPE firmware, which can differ from the version of SPE firmware you download. For more information about how Cisco IOS software processes multiple SPE firmware versions, refer to the earlier sections "Choosing an Update Strategy" and "SPE Firmware Scenarios" on page 11. |
Note You must be a registered Cisco user to log in to Cisco's Software Center. |
You can download software from the Cisco Systems CCO TFTP server using an Internet browser or using an FTP application. Both procedures are described.
Note To download SPE firmware from CCO to a PC and then upgrade the SPE firmware to an access server connected to your PC via an Ethernet hub, you need to set up a TFTP application on your PC, establish a HyperTerminal session, and make sure your PC and access server are correctly connected and talking before downloading the SPE firmware from CCO. All these procedures are described in "Upgrading SPE Firmware from Diskettes," later in this document. |
Step 2 Bring up Cisco's Software Center home page at the following URL (this is subject to change without notice):
http://www.cisco.com/kobayashi/sw-center/
Step 3 Click Access Products (under Cisco Software Products) to open the Access Products window.
Step 4 Click Cisco AS5800 Series Software.
Step 5 Click the SPE firmware you want and download it to your workstation or PC. For example, to download SPE firmware for the NextPort, click Download NextPort Images.
Step 6 Click the SPE firmware file you want to download, and then follow the remaining download instructions. If you are downloading the SPE firmware file to a PC, make sure you download it to the c:\tftpboot directory; otherwise, the download process will not work.
Step 7 When the SPE firmware is downloaded to your workstation, transfer the file to a TFTP server in your LAN using a terminal emulation software application.
Step 8 When the SPE firmware is downloaded to your workstation, transfer the file to a TFTP server somewhere in your LAN using a terminal emulation software application.
Note The directory path leading to the SPE firmware files on cco.cisco.com is subject to change without notice. If you cannot access the files using an FTP application, try the Cisco Systems URL http://www.cisco.com/kobayashi/sw-center/. |
Step 2 Enter your CCO registered username and password (for example, harry and letmein):
Step 3 Specify the directory path that holds the SPE firmware you want to download. For example, the directory path for the Cisco AS5800 SPE firmware is /cisco/access/5800:
Step 4 View the contents of the directory with the ls command:
Step 5 Specify a binary image transfer:
Step 6 Copy the SPE firmware files or Cisco IOS images from the ftp server to your local environment with the get command.
Step 7 Quit your terminal session:
Step 8 Verify you successfully transferred the files to your local directory:
Step 9 Transfer these files to a local TFTP or RCP server that your access server can access.
The procedure for copying the SPE firmware file from your local TFTP server to the UPCs is a two-step process. First, transfer the SPE firmware to the access server's Flash memory. Then, configure the SPEs to use the upgrade firmware. The upgrade will occur automatically, either as you leave configuration mode, or as specified in the configuration.
These two steps are performed only once. After you copy the SPE firmware file into Flash memory for the first time, you should not have to perform these steps again. Because the SPE firmware is configurable for individual SPEs or ranges of SPEs, the Cisco IOS software automatically copies the SPE firmware to each SPE whenever-- the access server restarts.
The following procedure assumes your terminal is connected directly to the console port on the AS5800 router shelf. Use these steps to download the NextPort SPE firmware to flash:
Step 2 Enter the copy tftp flash command to download the code file or IOS image from the TFTP server into the router shelf Flash memory. You are prompted for the download destination and the remote host name.
Step 3 Verify the file has been copied into the router shelf Flash memory:
Step 4 Disconnect the terminal from the router shelf, and connect it to the console port on the dial shelf's dial shelf controller card.
Step 5 Enter the copy tftp flash command to download the code file from the TFTP server into the dial shelf Flash memory. You are prompted for the download destination and the remote host name.
To configure the SPEs to use an upgraded firmware file:
Step 2 Enter your password.
You are in privileged EXEC mode when the prompt changes to AS5800#
Step 3 Enter global configuration mode by typing the configure command. The example uses the terminal configuration option.
You are in global configuration mode when the prompt changes to AS5800(config)#
.
Step 4 Enter SPE configuration mode, which is similar to the line configuration mode. You can choose to configure a single SPE or range of SPEs by specifying the first and last SPE in the range.
You are in SPE configuration mode when the prompt changes to AS5800(config-SPE)#
.
Step 5 Specify the SPE firmware file in Flash memory to use the for the selected SPEs.
Step 6 Specify when the SPE firmware upgrade will occur.
Step 7 Type the exit command to exit out of SPE config mode.
Step 8 Press the Return key to verify your command registers, then type Ctrl-Z to return to privileged EXEC mode.
Step 9 Save your changes when ready.
This section describes how to copy SPE firmware from diskettes to your hard disk in a PC environment, and then upload the SPE firmware to the SPEs. The steps are similar if you are using a Macintosh or UNIX workstation.
Note If you loaded Cisco IOS software from a feature pack CD-ROM using Router Software Loader (RSL), note that the CD contains a TFTP server program for PCs using Microsoft Windows. Run the TFTP server program from the directory where you installed the RSL program. Remember to set the root directory to the directory where the Cisco AS5800 SPE firmware is located. The RSL and the TFTP applications are also available on CCO in the software library in the Access Products section. |
This section describes how to copy the SPE firmware file to your hard disk in a PC environment. The steps are similar if you are using a Macintosh or a UNIX workstation.
Step 2 Create a folder named tftpboot at your hard disk root c:.
Step 3 Copy the SPE firmware file into the c:/tftpboot folder.
If you are using a PC running Microsoft Windows, upgrading SPE firmware from a hard drive onto a Cisco AS5800 involves installing a TFTP application on your PC, connecting your PC and the access server, establishing a HyperTerminal session on your PC, pinging the PC and access server to make sure they are talking to each other, and finally, copying the SPE firmware from the PC to the access server. See the following sections for details.
Note The steps are similar if you are using a Macintosh or a UNIX workstation. |
Note You can use any TFTP or rcp application available from independent software vendors. A number of TFTP programs are also available as shareware from public sources on the World Wide Web. If you are using Microsoft Windows, you can also download a TFTP application (as zipped files) from the Cisco web site at http://www.cisco.com/public/sw-center/sw-other.shtml. |
Step 2 Launch the TFTP application. You commonly do this by double-clicking the application icon or its filename.
Step 3 Set your TFTP server root directory:
Caution If you do not select the c:\tftpboot directory as your TFTP server directory, you will not be able to perform the copy procedure. This also applies if you are using RCP on your system. |
Note You can also connect your PC Ethernet port to the Cisco AS5800 Ethernet port using the 10BaseT crossover cable provided. |
Step 2 Connect your PC COM port to the Cisco AS5800 console port, as shown in Figure 5.
Step 3 Make sure your PC and access server are powered ON.
Use the steps in this section to establish a HyperTerminal session from your local PC to the Cisco AS5800. You will use the HyperTerminal session to talk to the access server.
Step 2 Double-click Hypertrm.exe to display the Connection Description dialog box.
Step 3 Enter a name for your connection, for example, Console and then click OK. HyperTerminal displays the Phone number dialog box.
Step 4 Choose the COM port connecting the PC and the access server in the Connect Using list box. You have options to connect directly to one of four COM ports.
Step 5 Click OK. HyperTerminal displays the COM Properties dialog box.
Step 6 Choose these options in the COM Properties dialog box:
Step 7 Click OK. The HyperTerminal dialog box appears.
Step 8 Press Enter to display the AS5800#
prompt.
Note If the access server prompt does not appear, you may have selected the wrong COM port, the cable connections could be incorrect or bad, or the access server may not be powered on. |
Ping the access server and the PC to make sure they are talking to each other and there are no configuration problems on your access server.
a. Choose Start/Run to display the Run dialog.
b. Enter winipcfg and click OK to display the IP Configuration dialog box.
c. Choose the PC Ethernet adapter connector used for the connection to the access server if you have more than one Ethernet adapter connector installed on your PC.
Note Enter the show running config command at the AS5800# prompt to verify the access server has an IP address assigned. If the access server does not have an IP address, assign an IP address before continuing. |
Step 2 In the HyperTerminal dialog box (see the previous section "Establish a HyperTerminal Session"), enter the access server enable mode (the prompt is displayed as AS5800#
):
Step 3 Enter the ping command with your PC's IP address.
The access server displays five exclamation points (!) if everything is working and it displays five dots (.) if there is a problem. In the latter case, check the cabling between the router and the PC and check the access server configuration.
The procedure for copying the SPE firmware file from your PC set up as a local TFTP server to the access server system Flash memory is a two-step process:
Perform these two steps only once. After you copy the SPE firmware file into system Flash memory for the first time, you should not have to perform these steps again. Because the code runs from the SPEs, the Cisco IOS software must automatically copy the SPE firmware to each SPE whenever the access server restarts.
Use these steps to download the NextPort SPE firmware to Flash memory:
Step 2 Enter the copy tftp flash command to download the code file from the TFTP server into the access server Flash memory. You are prompted for the download destination and the remote host name.
Step 3 Verify the file has been copied into the access server Flash memory:
To configure the SPEs to use an upgraded firmware file:
Step 2 Enter your password.
You are in privileged EXEC mode when the prompt changes to AS5800#
Step 3 Enter global configuration mode by typing the configure command. The example uses the terminal configuration option.
You are in global configuration mode when the prompt changes to AS5800(config)#
.
Step 4 Enter SPE configuration mode, which is similar to the line configuration mode. You can choose to configure a single SPE or range of SPEs by specifying the first & last SPE in the range.
You are in SPE configuration mode when the prompt changes to AS5800(config-SPE)#
.
Step 5 Specify the SPE firmware file in flash to use the for the selected SPEs.
Step 6 Specify when the SPE firmware upgrade will occur.
Step 7 Type the exit command to exit out of SPE config mode.
Step 8 Press the Return key to verify your command registers, then type Ctrl-Z to return to privileged EXEC mode.
Step 9 Save your changes when ready.
Use this procedure to update SPE firmware on the SPEs in your access server if you decide to use the version of SPE firmware bundled with Cisco IOS software instead of the version already mapped to your ports.
To set the SPE firmware mapping to the SPE firmware version bundled with Cisco IOS software, enter the following commands:
Step 2 Enter your password.
You are in privileged EXEC mode when the prompt changes to AS5800#
Step 3 Enter global configuration mode by typing the configure command. The example uses the terminal configuration option.
You are in global configuration mode when the prompt changes to AS5800(config)#.
Step 4 Enter SPE configuration mode, which is similar to the line configuration mode. You can choose to delete the configuration for a single SPE or range of SPEs by specifying the first & last SPE in the range. The SPE firmware used by the SPEs will automatically revert to the version bundled with the current Cisco IOS image.
You are in SPE configuration mode when the prompt changes to AS5800(config-SPE)#
.
Step 5 Change the Specify the SPE firmware file in flash to use the for the selected SPEs.
Step 6 Specify when the SPE firmware upgrade will occur (if used).
Step 7 Type the exit command to exit out of SPE config mode.
Step 8 Press the Return key to verify your command registers, then type Ctrl-Z to return to privileged EXEC mode.
Step 9 Save your changes when ready.
This process does not delete any existing SPE firmware that resides in system Flash memory in case you later want to revert to it. If you decide to delete the code from system Flash memory, remember that all files in system Flash memory will be deleted, therefore save and restore any important files (for example, the Cisco IOS software image).
Note If the new Cisco IOS image contains the same SPE firmware as the old one, no new code will be downloaded to the SPEs. |
