Command Reference

Command Reference

This appendix discusses all aspects of the command set. A list of top-level commands is provided in Table A-1.

Command-Line Processing

The user interface for the admin. port on the concentrator is a basic command-line interpreter. Commands and parameters are not case sensitive and can be abbreviated if they contain enough characters to eliminate any ambiguity with other commands at the same level. Command-line editing is provided along with history substitution. If you incorrectly enter a command, a usage message gives you the correct command format. Pressing Ctrl-W deletes the last word typed and pressing Ctrl-U deletes the entire line.

History Substitution Buffer

Commands entered during a terminal session are stored in a history substitution buffer. Commands in this buffer can be repeated or edited in a style similar to the UNIX C shell. The buffer stores the last twenty commands entered during a terminal session. (See the section "history Command" later in this appendix.)

To repeat a recent command, do the following:

   !! -- repeat the most recent command   !nn -- repeat command nn  !aaa -- repeat the command beginning with string aaa !?aaa -- repeat the command containing the string aaa

To modify and repeat the most recent command, do the following:

^aaa^bbb -- replace the string aaa with the string bbb in            the most recent command

To add a string to the end of a previous command and repeat it, do the following:

    !!aaa -- add string aaa to the end of the most recent command   !nn aaa -- add string aaa to the end of command nn  !aaa bbb -- add string bbb to the end of the command beginning             with string aaa !?aaa bbb -- add string bbb to the end of the command containing                       the string aaa

Connecting to Concentrator Administration

You can connect to the admin. interface through the admin. port (EIA/TIA-232) or via Telnet. The admin. port allows fixed baud rates. Telnet and admin. port sessions are automatically logged out if they are idle for 20 minutes.

Use the admin. interface to perform the following functions:

Connection via EIA/TIA-232

You can connect through the admin. port via EIA/TIA-232. Following is a sample display:

Cisco Systems Console Enter password: console> console> console> quit

Connection via Telnet

To use Telnet, you must have the IP address configured on the concentrator. To access the concentrator with Telnet, use the following procedure:

Step 1 On the remote host, enter the following command, where hostname is the host name or IP address of the concentrator:

%telnet hostname

Step 2 Enter the admin. interface password.

Step 3 When you finish, enter quit to exit the Telnet session. Following is a sample Telnet session:

% telnet concentrator1 Trying 192.XXX.XXX.XXX ... Connected to concentrator1. Escape character is '^]'. Cisco Systems Console Enter password: console> console> console> quit Connection closed by foreign host.

Top-Level Commands

See also set trap and show snmp.

configure Command

The configure command downloads a configuration file or a batch file from the network and executes each command in that file. It is only available in privileged mode. The file should contain only American Standard Code for Information Interchange (ASCII) text and should not exceed 9,216 bytes (9 kilobytes [KB]) in length. Administrator commands are entered one per line.

The list of commands should end with the word "end" followed by a carriage return. The file may also contain comment lines, which are indicated by a pound (#) character at the beginning of each line. Some commands prompt for user input or confirmation. Responses to such commands should appear on the line after the command prompt.


Note Some confirmations in a Telnet session are not prompted for in EIA/TIA-232 port sessions--for example, set ipaddress and set port disable.

Following are examples of configuration files:

show time set ipalias conc5 192.1.1.205 set ipalias montreux 192.1.1.10 set ipalias bigbird 198.1.1.8 set prompt conc5> set password #the next line is empty because the old password is an empty string pingpong pingpong end Console> (enable) configure help Usage: configure network configure terminal configure <host> <file> Console> (enable) configure 198.1.1.8 conc5.cfg Configure using file conc5.cfg from host 198.1.1.8.(y/n) [n]? y Configuring using conc5.cfg from 198.1.1.8 Done.

See also show config and write Command.

connect fddi Command

The connect fddi command connects the concentrator to the FDDI ring. Following is a sample display:

Console> (enable) connect Usage: connect fddi Console> (enable) connect fddi Connected to FDDI ring. Console> (enable)

See also disconnect fddi Command.

copy flash tftp Command

The copy flash tftp command uploads the Flash memory image file from the concentrator to a network host to create a backup file. The file must be created in advance and saved in the tftpboot directory. Following is a sample display:

Console> (enable) copy flash tftp

IP address or name of remote host? oscar Name of file to copy to? c1400_conc3.net Upload image from flash to file c1400_conc3.net on host oscar (y/n) [n]? y Uploading image to c1400_conc3.net on oscar / Done. Finished Network Upload. (446468 bytes) Console> (enable)

copy tftp flash Command

The copy tftp flash command downloads a Flash memory image file from the tftpboot directory to Flash memory. The binary file is searched for in the tftpboot directory of the host designated by IP address or name. The file transfer process can be stopped by pressing Ctrl-C. The copy tftp flash command and the download command are identical.

Caution  Do not reset the concentrator after the Flash memory initialization process begins. The Flash memory image file may be incomplete and would cause system failure.

Following is a sample display:

Console> (enable) copy tftp flash IP address or name of remote host? oscar Name of file to copy from? c1400_10.net This command will disconnect your telnet session. Download image c1400_10.net from host oscar to flash (y/n) [n]? y Downloading image c1400_10.net from oscar / Done. Finished Network Download. (440324 bytes) Initializing flash...Erasing Flash..Done Programming Flash Base...Code...Length...Time...Done Disconnected from FDDI ring. Connection closed by foreign host. %

disable Command

The disable command returns you to normal mode. Following is a sample display:

Console> (enable) disable Console>

See also enable and set enablepass.

disconnect fddi Command

The disconnect fddi command disconnects all CDDI/FDDI ports from the FDDI ring. The disconnect fddi command will also terminate any network connections, including services such as Telnet. After the concentrator is reset, it attempts to connect all ports even if you had previously issued a disconnect fddi command.

Following are samples of the disconnect fddi command with two connection types:

Console> (enable) disconnect Usage: disconnect fddi Console> (enable) disconnect fddi This command will disconnect all CDDI/FDDI ports. Do you want to continue (y/n) [n]? y Disconnected from FDDI ring. Console> (enable) Console> (enable) disconnect fddi This command will disconnect all CDDI/FDDI ports and your    telnet session. Do you want to continue (y/n) [n]? y Disconnected from FDDI ring. Connection closed by foreign host. %

See also connect fddi Command


Note After using the disconnect command, network connections can be resumed with the connect command locally or by resetting the concentrator.

download Commands

There are two ways to download a new image to Flash memory: through the serial port using the download serial command or over the network using the download host file command.

download

The download command enables you to download data to the concentrator over the network. When you download over the network, the concentrator expects a binary image. Network download is achieved via TFTP. The binary file image is searched for in the tftpboot directory. You can cancel the download command during the TFTP process by pressing Ctrl-C. The download command and the copy tftp flash are identical.

Caution Do not reset the concentrator after the download process begins. The Flash memory image file may be incomplete and would cause system failure.

Note Downloading an image file over the network will take about two minutes during normal traffic conditions.

Following is an example of a network download in a Telnet session:

Console> (enable) download Usage: download serial download <host> <file> (serial downloads via the administration RS-232 port, host is ipalias or IP address: a.b.c.d for a network download (NOTE: FDDI ring will go down) Console> (enable) download cres c1400_10.net This command will disconnect your telnet session. Download image c1400_10.net from host cres to flash (y/n) [n]? y Downloading image c1400_10.net from cres / Done. Finished Network Download (409604 bytes) Initializing flash...Erasing Flash....Done Programing Flash Base....Code....Length....Time....Done Disconnecting from the FDDI ring. Connection closed by foreign host. %

download serial

When you download through the serial port, the concentrator expects an ASCII image. You must ensure that the baud rates from the sending and receiving end are the same.


Note Downloading an image file through the serial port will take about 20 minutes.

The following display shows a serial download session through the EIA/TIA-232 port using Kermit for a UNIX workstation:

enable Command

The enable command is used to enter privileged mode. Following is a sample display:

Console> Console> enable Enter password: Console> (enable)

See also disable and set enablepass.

help Command

The help command displays the following information in normal mode. (The ? command is the same as the help command.) Following is a sample display:

Console> help Commands: ------------------------------------------------------------------------ enable Enable privileged mode help Show this message history Show contents of history substitution buffer ping Send echo packets to hosts quit Exit out of the console set Set, use 'set help' for more info show Show, use 'show help' for more info Console>

history Command

The history command shows the last 20 commands you entered, as follows:

Console> history 2 history 3 history 4 configure help 5 show help 6 show system 7 show snmp 8 show time 9 show port 10 show mac 11 help 12 set ipalias 198.122.174.205 marketing 13 set netmask 255.255.255.0 14 show snmp 15 set ipalias bedrock 192.122.173.125 16 set ipalias marketing 192.122.173.40 17 set ipalias bigbird 192.122.173.42 18 show ipalias 19 show time 20 disable 21 history Console>

macreinit Command

The macreinit command reinitializes the primary and secondary MACs. You could use the macreinit command to clear a halted concentrator. Following is a sample display:

Console> (enable) macreinit

MACs reinitialized.

Console> (enable)

ping Command

The ping command sends Internet Control Message Protocol (ICMP) echo request packets to a node on the network. When the -s option is specified, the ping command sends one datagram per second and prints one line of output for every response it receives. No output is produced if there is no response. Also, when the -s option is specified, round-trip times and packet-loss statistics are computed, and a summary of this information is shown on termination or timeout. The default packet size is 64 bytes, or you can specify a size from 1 to 2,000 bytes.

If you give an optional packet count, the ping command sends only that number of requests. Following is a sample display of the ping command:

Console> ping Usage: ping <host> ping -s <host> [data_size] [packet_count] (host is ipalias or IP address in dot notation: a.b.c.d) Console> ping bedrock no answer from bedrock Console> ping elvis elvis is alive Console> ping -s elvis 58 5 PING elvis: 58 data bytes 66 bytes from elvis: icmp_seq=0. time=13 ms 66 bytes from elvis: icmp_seq=1. time=5 ms 66 bytes from elvis: icmp_seq=2. time=5 ms 66 bytes from elvis: icmp_seq=3. time=5 ms 66 bytes from elvis: icmp_seq=4. time=7 ms ----elvis PING Statistics---- 5 packets transmitted, 5 packets received, 0% packet loss round-trip (ms) min/avg/max = 5/7/13 Console> ping -s ariel PING ariel: 56 data bytes 64 bytes from ariel: icmp_seq=46. time=14 ms 64 bytes from ariel: icmp_seq=47. time=8 ms 64 bytes from ariel: icmp_seq=48. time=7 ms 64 bytes from ariel: icmp_seq=49. time=8 ms 64 bytes from ariel: icmp_seq=50. time=9 ms 64 bytes from ariel: icmp_seq=51. time=7 ms 64 bytes from ariel: icmp_seq=52. time=6 ms 64 bytes from ariel: icmp_seq=53. time=8 ms 64 bytes from ariel: icmp_seq=54. time=9 ms ^C ----ariel PING Statistics---- 55 packets transmitted, 9 packets received, 83% packet loss round-trip (ms) min/avg/max = 6/8/14 Console>

set insertmode

Workgroup WS-C1400 Concentrators support insertion of stations attached to the concentrator M port into the FDDI ring so that no data frames are lost in the process. This form of insertion is called scheduled insertion. Without scheduled insertion, frames can be lost while connecting to a new station.

You can change port insertion mode using the set insertmode command, which sets the system insert mode to standard or scheduled. The default is scheduled.

Following is a sample display:

Console> (enable) set insertmode Usage: set insertmode <standard|scheduled> Console> (enable) set insertmode standard System insert mode set to standard. Console> (enable) set insertmode scheduled System insert mode set to scheduled. Console> (enable)

You can display the insertion mode of the concentrator by using the show system command. The Ins-Mode field displays the insert mode of the M ports.

set ipaddress

The set ipaddress command sets the IP address. The netmask and broadcast addresses needed for SNMP, ping, Telnet, or TFTP can be set at the same time. Following are two sample displays.

EIA/TIA 232 example:

See also show system.

set module

The set module command will enable or disable the module. Disabling the module disconnects all ports and isolates the module from the main paths at the configuration control element (CCE) level on the motherboard. This allows removal of the module from the concentrator without creating additional ring disruptions. After installing the module use the set module command to enable the module. The variables are as follows:

Following is a sample display:

Console> (enable) set module ? Usage: set module <module_num> <enable|disable> Console> (enable) Console> (enable) set module 2 disable This command may disconnect your telnet session. Do you want to continue (y/n) [n]? y Module 2 disabled. Console> (enable) set module 2 enable Module 2 enabled. Console> (enable)

See also show system.

set netmask

The set netmask command sets the IP subnet mask. The subnet mask specifies the subnet field of IP addresses and consists of a 32-bit mask written in dotted-decimal format. Following is a sample display:

Console> (enable) set netmask Usage: set netmask <a.b.c.d> Console> (enable) set netmask 255.255.255.0 Netmask changed. Console> (enable)

set password

The set password command sets the concentrator login password. You are prompted for the old password followed by the new password twice if the old password checks. A zero-length password is allowed, but passwords must not exceed 20 characters.


Note The default is no password configured.

If you forget your password, you have 30 seconds after power up or pressing the reset button to log in without a password and change the password. This requires physical access to the concentrator.

Following is a sample display:

Console> (enable) set password Enter old password: Enter new password: Retype new password: Password changed. Console> (enable)
Note The passwords entered will not echo to the terminal display.

set path

The set path command sets individual ports to primary or secondary ring paths. The default is primary. Following is a sample display:

Console> (enable) set path

Usage: set path <mod_num/port_num> <primary|secondary> Console> (enable) set path 1/4 secondary Port 1/4 requested path set to secondary. Console> (enable)

See also show port.

set port

The set port command enables and disables a port. The default is enabled. Following is a sample display:

Console> (enable) set port

Usage: set port <mod_num/port_num> <enable|disable> Console> (enable) set port 1/2 enable Port 1/2 enabled. Console> (enable)

The format of the set port command follows:

See also show port.

set portname

The set portname command configures a name for a port. The default port name is no name. The variables available are as follows:

Following is a sample display:

Console> (enable) set portname ? Usage: set portname <mod_num/port_num> [name_string] Console> (enable) set portname 1/2 marketing Port 1/2 name set. Console> (enable)

The port name you enter will appear in the port information display of the show port command. You can enter any port name up to 20 characters in length. A zero-length port name clears the name. Port names are only meaningful to network administrators and are not used by the concentrator.


Note You may find that associating the ports to the names of the attached devices makes system administration easier and reduces the chance of accidentally disconnecting the wrong workstation.

set prompt

The set prompt command changes the prompt for the command line of the admin. interface. The default prompt is Console>. Following is a sample display:

Console> (enable) set prompt Usage: set prompt <prompt_string> Console> (enable) set prompt conc5> conc5>
Note You may find it useful to set a more meaningful prompt, such as the location of the concentrator or the name of a workgroup.

set redirect

The set redirect command enables or disables the ICMP redirects, allowing or disallowing dynamic updates to the routing table. The default is enabled. Following is a sample display:

Console> (enable) set redirect ? Usage: set redirect <enable|disable> Console> (enable) set redirect enable ICMP Redirects enabled. Console> (enable)

See also show snmp.

set route

The set route command adds IP routing table entries. Its variables are as follows:

Following is a sample display:

Console> (enable) set route ?

Usage: set route <destination> <gateway> [metric] (destination and gateway are ipalias or IP address in dot notation: a.b.c.d) Console> (enable) set route fddi 198.133.219.40 1 Route added. Console> (enable)

You can enter either an IP address in dotted-decimal format or an alias, if one is set. Add an entry for the destination network and the gateway IP address if you want to manage the concentrator from a network management workstation that is not on the local network.

Figure A-1 shows two sample networks. In example A, the concentrator needs a path to a network management workstation located on another network through a router. In this case, you must add an entry in the routing table using the set route command. For example:

set route 124.4.34.0 192.45.67.4

In example B, the network management workstation is located on the same network as the concentrator, so you do not need to add an entry in the table.

Note Connection policies cannot be configured with the admin. interface.

Table  A-5: Bit Location Connection Policies and Definitions
Bit Location Connection Policy Policy Definition
0 (LSB)1 Reject A-A An undesirable peer connection that creates twisted primary and secondary rings.
1 Reject A-B Normal trunk ring-to-peer connection.
2 Reject A-S Undesirable peer connection that creates a wrapped ring.
3 Reject A-M Tree connection with possible redundancy.
4 Reject B-A Normal trunk ring-to-peer connection.
5 Reject B-B Undesirable peer connection that creates twisted primary and secondary rings.
6 Reject B-S Undesirable peer connection that creates a wrapped ring.
7 Reject B-M Tree connection with possible redundancy.
8 Reject S-A Undesirable peer connection that creates a wrapped ring.
9 Reject S-B Undesirable peer connection that creates a wrapped ring.
10 Reject S-S Connection that creates a single ring of two slave stations.
11 Reject S-M Normal tree connection.
12 Reject M-A Tree connection that provides possible redundancy.
13 Reject M-B Tree connection that provides possible redundancy.
14 Reject M-S Normal tree connection.
15 (MSB)2 Reject M-M An illegal connection that creates a "tree of rings" topology.

1 LSB = least significant bit.
2 MSB = most significant bit.

The value displayed in the connection policy field is a four-digit hexadecimal number in which each digit corresponds to four of the bit positions in the table. The interpretation of the number 8000 is shown in Figure A-8.


Figure A-8:

Interpreting the Conn-Pol Hexadecimal Number

For example, assume the Conn-Pol value for the concentrator is 8000. Reading the hexadecimal numbers from right to left, note that bits 0 though 3 are not set, bits 4 through 7 are not set, bits 8 through 11 are not set, and bits 12 through 14 are not set; however, bit 15 is set. Look at Table A-5 to see what policy corresponds to bit 15. In this case, an M-M port connection is rejected.

test trap

The test trap command sends an SNMP trap message to the trap receivers. Following is a sample display:

Console> (enable) test trap

Usage: test trap <trap_num> [specific_num] Console> (enable) test trap 1 SNMP trap message sent. Console> (enable)

See also clear trap and set trap.

traffic Command

The traffic command sends continuous traffic on the ring, as follows:

Console> (enable) traffic Usage: traffic <FC> <DA> <SA> random <LEN> <PKTS> traffic <FC> <DA> <SA> percent <CENT> (FC is any valid FDDI Frame Class in hex format. DA and SA are hex MAC addresses in FDDI format separated by :, ex: a:0:45:21:2:6 LEN = length of packet, PKTS = Number of packets) Console> (enable) traffic 41 00:40:0b:80:e0:48 00:40:b0:80:e0:c8                 random 64 100 Generating Random data at maximum rate....Done Console> (enable) traffic 41 00:40:0b:80:e0:48 00:40:b0:80:e0:c8                 percent 60 Generating Traffic at 60% = Packet rate of 1666 packets/sec = Inter-packet gap time of 239 usec = Wait loop count of 225 HIT ANY KEY TO STOP TRAFFIC GENERATION ..Percentage traffic stopped Console> (enable)

The traffic command sets the concentrator in traffic generation mode. You can specify the number, type, and content of packets to be generated. The traffic is generated by the primary MAC only.


Note While traffic is generated as a result of a traffic command, the concentrator may not respond to admin. interface or Workgroup Director commands. These modes should return once the concentrator is reset.

The following options are available with the traffic command:

Refer to the sample network in Figure A-14 when you read the following examples of the traffic command.

To generate packets with random data, use the following command:

traffic 51 00:02:D0:02:00:35 00:02:D0:01:00:08 random 100 10000

This command generates 10,000 frames of 100 bytes, each containing random data. The traffic generation ceases either after all the frames have been generated or if the ring goes down for any reason.

The LEN parameter in the previous command (100) example can be any valid FDDI frame length. Note that the length you specify includes the frame class and address fields. The data bytes in the frames are all set to zero and packets are generated by the MAC at the fastest possible rate.

To generate traffic at a fixed rate, use the following command:

traffic 51 00:02:D0:02:00:35 00:02:D0:01:00:08 percent 78

This command generates 78 percent traffic on the ring. Each frame contains the same random data and is 4,492 bytes in length. For every new percent traffic command, new random data is generated. The mode of traffic generation stops either if the ring goes down or if any key on the keyboard is pressed. Note that there may be a slight deviation from the exact percentage.


Figure A-14:

Example Connection for the traffic Command

Always reset the concentrator following traffic generation. This will ensure proper behavior of the node.

upload Command

The upload command uploads the Flash memory image file from the concentrator to a network host to create a backup file. The file must be created in advance and saved in the tftpboot directory.

The upload command performs the same function as the copy flash tftp command.

Following is a sample display: Console> (enable) upload Usage: upload <host> <file> (host is ipalias or IP address: a.b.c.d file must already exist in tftp directory.) Console> (enable) upload oscar c1400_conc3.net Upload flash image to file c1400_conc3.net on host oscar (y/n) [n]? y Uploading image to c1400_conc3.net on 198.133.219.40 / Done. Finished Network Upload. (446468 bytes) Console> (enable)

See also copy tftp flash Command.

write Command

The write command writes the concentrator configuration either to an existing file in a network host tftpboot directory or to the terminal screen display.

The ASCII configuration file uploaded by the write terminal command can be used to configure the same concentrator or edited to configure another WS-C1400 concentrator. (See the section "configure Command" earlier in this appendix.) The uploaded file is the same output as the files generated by the show config and write terminal commands, with the following exceptions:

The blank line is needed to display the confirmation prompt with the no default. When these commands are called from a Telnet session, they will not be executed because they may disconnect the Telnet session. We recommend you execute the configure command from the EIA/TIA-232 connection, not from a Telnet session.

The write terminal command functions the same as the show config command.

Following is a sample display:

Console> (enable) write ?

Usage: write network write terminal write <host> <file> Console> (enable) write cres 06.29.config Write file 06.29.config on host cres (y/n) [n]? y Uploading configuration to 06.29.config on cres Done. Finished Network Upload (5135 bytes) Console> (enable)

See also configure Command.
