This section describes the following topics:
The following information about RSL operations can help you with the installation process:
If any of the following elements apply to your installation, modify the Short Timeout value from the Options dialog box in RSL:
"Failed to configure the router to enable the Cisco IOS software image and configuration file upload and download operations. You may want to check the router to make sure that the selected interface exists."
If you are connecting to any other router or access server, increase the Short Timeout to a value over 25 seconds.
|
Note If you change the timeout value, you must do so before connecting to the Catalyst 8500 CSR, or the new value will not be used. Also, increasing the Short Timeout value can increase the time it takes for RSL to connect to the target Catalyst 8500 CSR. |
In some cases, RSL is unable to restore the startup configuration. If this happens, follow these steps:
Step 2 Restart RSL and connect by using the Preconfigured router option.
Step 3 When asked if you want to overwrite the existing startup configuration file, choose no.
Step 4 When asked if you want to continue, choose yes.
Step 5 When the Catalyst 8500 CSR is connected, select Download Router Configuration in the Router Software Loader dialog box.
Step 6 Select the appropriate file and click the radio button beside Copy configuration to the router nonvolatile memory. The Catalyst 8500 CSR should now contain the startup configuration it had before the initial RSL connection.
Step 7 Exit RSL.
|
Note In the steps above, the Catalyst 8500 CSR configuration register (config-register 0xnnnn) is not restored. |
|
Note If you press Ctrl-Alt-Delete to quit RSL, the router configuration and the configuration register are not restored. However, the configuration file is not deleted from the PC. To restore the configuration file, follow the steps above, beginning with Step 2. |
RSL is designed to work with a PC running Microsoft Windows 95 and is the recommended method for downloading software to the Catalyst 8500 CSR; however, you can install the software using the TFTP process described in the following section.
|
Note The sample prompts and output shown in the following sections might not be identical to the prompts displayed on the Catalyst 8500 CSR console. |
Use this TFTP server application method as an alternative method to install the Catalyst 8500 CSR software from the CD-ROM. You can perform this procedure by using a PC (running Microsoft Windows 95 or Microsoft Windows 3.1), a Macintosh, or a UNIX system. You can use either the copy tftp flash or copy rcp flash command to download the software to the Catalyst 8500 CSR.
First, obtain a TFTP application or a remote copy protocol (rcp) application to set up your computer as a TFTP server or an rcp server. If you are using a PC running Windows 95, you can use RSL or the TFTP server included on the feature pack CD-ROM to install the Catalyst 8500 CSR software. For other operating systems, a number of TFTP or rcp applications are available from independent software vendors, or as shareware on the World Wide Web.
|
Note To use an rcp application, follow the same procedure below, but substitute "rcp" for "TFTP" and use the copy rcp flash command instead of the copy tftp flash command. |
Step 2 Start the TFTP server application on the PC by double-clicking the application icon or its .exe filename.
Step 3 Set up the PC as a TFTP server by using the TFTP server application setup or configuration facility.
Most TFTP server applications include a setup facility that allows you to specify the PC as a server. For example, from the TFTP menu of one application, select Settings to display a panel. To configure the local PC as a server, select the Server checkbox.
Select a root directory where the Cisco IOS files reside (for example, d:\cpswinst\images).
 |
Caution Make sure you set up your local PC as a TFTP server. If you do not, you cannot perform the copy procedure. This caution applies to both TFTP and rcp. |
Step 4 Establish a console session from your local PC (which is now configured as a TFTP server) to the Catalyst 8500 CSR by using one of these methods:
This is the recommended method. When you reload the Catalyst 8500 CSR with the new image in
Step 13, you remain connected to the Catalyst 8500 CSR.
|
Caution Make sure that your PC is set up to communicate with the connected device through its network port. |
Step 5 Connect your PC's LAN port to the corresponding LAN port on the Catalyst 8500 CSR. If you are making a direct connection to the Catalyst 8500 CSR via Ethernet or Fast Ethernet, use an Ethernet crossover cable. If connecting to the Catalyst 8500 CSR via an Ethernet or Fast Ethernet hub or Token Ring MAU (hub), use straight-through cable.
|
Note We recommend that you back up the Catalyst 8500 CSR configuration before upgrading the Catalyst 8500 CSR software. |
Step 6 At the prompt, enter your password:
Step 7 At the prompt, enter enable; then enter your password:
Step 8 At the prompt, enter the following command to copy the new software image from the PC CD-ROM drive to the Catalyst 8500 CSR:
In the next series of steps, you download the Cisco IOS Release XX.X images that you want installed on your Catalyst 8500 CSR.
Step 9 At the prompt, enter the IP address of your PC, as shown in the following example:
Address or name of remote host [255.255.255.255]? 131.108.1.1
This is the IP address of your local PC, not that of the Catalyst 8500 CSR.
Step 10 At the prompt, enter the filename of the Cisco IOS Release 78-7045-08 image to be copied to the Catalyst 8500 CSR, as shown in the following example:
This example specifies the UNIX image name of the IP feature set for Catalyst 8500 CSR (as shown in Table 5 in the "Feature Pack Overview Table" section).
Step 11 At the prompt, enter the destination UNIX image filename and press Enter.
This is the name of the image file on the Catalyst 8500 CSR—not the full pathname of the image on the CD-ROM attached to the PC. Refer to Table 5 in the "Feature Pack Overview Table" section for the UNIX image filename.
During the transfer process, the software displays messages indicating that it has accessed the file you have specified and is loading it.
Step 12 At the prompt, enter yes if you want to erase the existing image copy resident in the Catalyst 8500 CSR Flash memory before copying the new one.
Erase flash device before writing? [confirm] yes
The entire copying process takes several minutes and differs from network to network.
The exclamation point (!) indicates that the copy process is taking place. Each exclamation point (!) indicates that ten packets have been transferred successfully. A checksum verification of the image occurs after the image is written to Flash memory.
Step 13 Enter the reload command to reload the Catalyst 8500 CSR:
After the reload is complete, the Catalyst 8500 CSR should be running the required Cisco IOS image. Use the show version command to verify it.
We recommend that you read the following application notes before configuring your switch router:
The Catalyst 8500 CSR ships with an 16 MB systemcode Single In-Line Memory Module (SIMM) for the onboard Flash memory software image.
To download and store a copy of the Catalyst 8500 CSR software image, we recommend using a minimum 20 MB Flash PC Card. This will allow you to have two or more images installed at the same time. See the "Memory Defaults and Upgrade Options" section.
The Catalyst 8500 CSR boots from its onboard Flash memory by default. To change this default to boot from a Flash PC Card instead, you must change the configuration register setting to 0x2102. Detailed instructions can be found in the Layer 3 Switching Software Feature and Configuration Guide.
This section describes the following Catalyst 8500 CSR restrictions:
The eight-port Gigabit Ethernet interface does not support an ACL daughter card.
The Catalyst 8510 CSR does not support an ACL daughter card.
UDP flooding is disabled on routers with an ACL daughter card.
The following ACLs are not supported with the ACL daughter card:
We recommend that you evaluate the level of CPU utilization and performance in your switch router before turning on AppleTalk, particularly in a Catalyst 8510 CSR. Unlike IP and IPX, AppleTalk routing and processing in the Catalyst 8500 CSR is accomplished by the switch processor, not the interface module. This means that routing AppleTalk packets consumes more processing time than routing other protocol packets. In a switch with a sustained high CPU utilization, turning on AppleTalk could result in longer convergence times for routing protocols like EIGRP. AppleTalk packet throughput is dependent on the amount of available CPU processing power.
The four adjacent ports (such as 0-3 or 4-7) on a 10/100 interface must all use the same VLAN encapsulation, that is, either 802.1Q and native, or ISL and native.
When assigning Ethernet interfaces to an EtherChannel, all interfaces must be either Fast Ethernet or Gigabit Ethernet. You cannot mix Fast Ethernet and Gigabit Ethernet interfaces within a single EtherChannel.
Catalyst 8500 line modules support a maximum of 2 paths. To improve EIGRP or OSPF convergence, set the maximum-paths for the router to 2, using the following command:
The snooping source port and destination port cannot be the same port.
You can only snoop with one source port and one destination port.
Snooping configuration information is not saved in NVRAM.
The Catalyst 8540 8-port Gigabit Ethernet line module can support a maximum of 24 ports per bridge group.
If your Catalyst 8540 CSR has an 8-port Gigabit Ethernet line module, you cannot create a port channel that has some members on that module and others on other modules. All port channel members must reside on the same Gigabit Ethernet line module.
Also, if your switch router has an 8-port Gigabit Ethernet line module, port channel IDs 57 to 64 are reserved, and cannot be assigned to other external interfaces. If you assign a port channel ID number greater than 56, the system will respond with the following message:
Port channel with ID > 56 cannot be created.
If you have already assigned port channel IDs 57 to 64, you must reassign them before installing an 8-port Gigabit Ethernet line module.
If your switch router does not have an 8-port Gigabit Ethernet line module, you can assign port channel ID numbers up to 64.
The following restrictions apply to the online insertion and removal (OIR), also known as hot swapping, of line modules on the Catalyst 8500 CSR:
On an 8540 CSR, the reprogram command for upgrading the FPGA on the switch processor requires power cycling the box after completing the FPGA download.
The Catalyst 8510 and 8540 CSR systems support extra long haul (1000BaseZX) GBICs as follows:
The Catalyst 8540 CSR supports the use of redundant route processors and switch modules. The second route processor would be installed in slot 8, and an additional switch module would be installed in slot 6.
There are some precautions that need to be taken before removing a route processor module from a chassis that is powered-up. If a route processor module that is currently running IOS is removed from the chassis in a skewed manner such that the left side of the processor comes out before the right side does, the traffic flowing through the device may stop flowing.
To avoid this, make sure the route processor module that is being removed is currently at the ROM monitor prompt; it is then safe to remove it from the chassis. One way to get the system into ROM monitor from IOS is to issue a reload command. This will work if the system is not configured to auto-boot. If the system is configured to auto-boot, it starts booting IOS again.
Since you need to ensure that a route processor is in ROM monitor before removing it, the redundancy prepare-for-cpu-removal command has been added to take the system to the ROM monitor prompt. Execute this command on the route processor being removed before removing it. Once this command is issued, the route processor will go to the ROM monitor prompt and stay there even if the system is configured to auto-boot. At this point it is safe to remove the route processor from the system.
If a Catalyst 8540 CSR has three switch modules, then by default the switch modules in slots 5 and 7 come up as active, and the one in slot 6 comes up as the standby. If you wish to change this default, there is a command that lets you select the "preferred" switch module slots. This command is a privileged exec level command with the following format:
redundancy preferred-switch-card-slot slot#1 slot#2
Two unique preferred slots must be specified. The range of the slot value is 5 to 7. If one of the preferred slots is not a currently active switch module, you are informed of this and asked if the system should change the active switch modules to the preferred switch modules. If such a switch-over occurs, all the active connections in the system will be reinitialized. If you wish to continue, then the preferred switch modules become active, and the other switch module becomes the standby. This configuration will remain in effect until either one of the active switch modules is removed.
The preferred switch module configuration is preserved across route processor switch-overs. However, the preferred switch modules setting will be lost if the system is power-cycled or if both route processors are reloaded to the ROM monitor.
Beginning with Cisco IOS Release 12.0(5)W5(13) software, the autonegotiation feature for speed and duplex on 10/100BaseT Ethernet ports defaults to "on." This means that for each port, the Catalyst 8500 CSR automatically detects the port speed (10 Mbps or 100 Mbps) and duplex of the peer port, if that port also autonegotiates.
To override autonegotiation and set a port to 10 Mbps operation, issue the following command:
To set a port to 100 Mbps operation, issue the following command:
To set the duplex value for a port to full-duplex, issue the following command:
To set the duplex value for a port to half-duplex, issue the following command:
|
Caution If you connect a Catalyst 8540 CSR running Cisco IOS Release 12.0(5)W5(13) software to a router or switch running in forced full-duplex mode, you may encounter symptoms such as high collision rate or reduced throughput, as the Catalyst 8540 unsuccessfully tries to autonegotiate with the other device. When autonegotiation fails, the Catalyst 8540 defaults to half-duplex operation, which causes a mismatch between it and the other device. Possible workarounds include forcing the Catalyst 8540 to operate in full-duplex mode or removing the full-duplex command from the other device. |
The Catalyst 8540 CSR line modules can be used in a Catalyst 8540 MSR chassis, with an MSR route processor and switch modules. If you do this, you must use only CSR (Ethernet) line modules, and you must load either the CSR software image on the MSR or use the ATM router module with the MSR software image.
The Catalyst 8540 CSR and 8510 CSR systems running Cisco IOS Release 12.0(0.6)W5(1) and later have been certified as Y2K Compliant. For more information, see the following URL: http://www.cisco.com/warp/public/752/2000/.
