Introduction

The Catalyst 2900 series switches now offer a 1000BaseX module in addition to the switched 10BaseT/100BaseTX and 100BaseFX modules. The 1000BaseX module allows you to install either a short-wavelength (SX) or long-wavelength (LX/LH) Gigabit Interface Converter (GBIC). These modules can add port density and fiber-optic connectivity or high-speed uplink to a Catalyst 2900 series XL network. The 10BaseT/100BaseTX module autonegotiates the duplex and speed settings of each port to match that of the attached device. The 1000BaseX module autonegotiates the duplex mode only.

Features

The following features are supported on the 1000BaseX module:

•VLAN integration

The module supports VTP and Media Access Control (MAC) address-based dynamic VLANs.

The module supports IEEE 802.1Q and Inter-Switch Link (ISL) tagging. See the Catalyst 2900 Series XL Command Reference publication and Catalyst 2900 Series XL Enterprise Edition Software Configuration Guide for VLAN configuration information.

•Per-VLAN spanning tree plus (PVST+)

An independent spanning tree instance runs on each VLAN. See the Catalyst 2900 Series XL Command Reference publication and Catalyst 2900 Series XL Enterprise Edition Software Configuration Guide for spanning-tree configuration information.

•Trunking (IEEE 802.1Q and ISL)

The module supports setting a trunk to IEEE 802.1Q or ISL mode. Enter the set trunk command to configure trunk ports and to add VLANs to the allowed VLAN list for existing trunks. See the set trunk command description in the Catalyst 2900 Series XL Command Reference publication.

•Port Security

See the Catalyst 2900 Series XL Enterprise Edition Software Configuration Guide for information about configuring port security on a port or range of ports.

•Autonegotiation
Caution   Autonegotiation with Gigabit Ethernet behaves differently than autonegotiation with Ethernet or FastEthernet. To avoid link configuration problems, refer to the Catalyst 2900 Series XL Enterprise Edition Software Configuration Guide for information about autonegotiation.

•Gigabit EtherChannel

Configure Gigabit EtherChannel by entering the set port channel command.

Important Notes

Switch Software Requirement

To use the Gigabit Ethernet module (WS-X2931-XL) with a Catalyst 2900 series XL switch, ensure that the switch is running IOS version SA5 or later. For information on upgrading the switch software, see "Upgrading Your Catalyst 2900 Series XL Switch Software."

Hot Swapping

Hot swapping is not supported in this release. When inserting a module in or removing a module from a switch, power off the switch. If you insert or remove a module while the switch is powered on, restart the switch using the reload command.

Caveat

This section contains a list of known problems and suggested workarounds.

Gigabit Interface Converter Data Integrity

Some Gigabit Interface Converters (GBICs) contain faulty data. Therefore, the GBIC information is not reliable. The software cannot detect that this is erroneous information, so it passes along the faulty data. If you select a cable based on this erroneous information, the module link will not come up. To work around this problem, select a cable based on the GBIC type printed on the label.

Upgrading Your Catalyst 2900 Series XL Switch Software

This section describes the procedure for upgrading your Catalyst 2900 series XL switch software by using the IOS command-line interface (CLI). To perform the steps in this section, you must have a TFTP server and a management station (such as a PC) with a CD-ROM drive. You must also access the switch management console by either of these two methods:

•Using a terminal emulation program (such as ProComm or HyperTerminal) and the supplied RJ-45-to-RJ rollover cable and adapters

•Using Telnet if an IP address is assigned to the switch

Downloading Files from CCO

Follow these steps to download the new software and TFTP server application:

Step 1 Display the Cisco home page by pointing your browser to one of the following URLs:

http://www.cisco.com

http://www-china.cisco.com

http://www-europe.cisco.com.

Step 2 Log into CCO. You might need to register the first time you log in.

Step 3 To locate the software files from the home page, access the FTP site at ftp://anonymous@ftpeng.cisco.com/ftp/dsbu/beta/SA5/.

Step 4 Follow the instructions on the page to download the IOS image.

Step 5 Follow the instructions on the page to download and configure the TFTP server.

Displaying the IP Address of the TFTP Server

Before you can download new software to your module, you need to enter the IP address of your PC or workstation on the System Management page. If you are running the Cisco TFTP server, the PC IP address is displayed on the application title bar.

If you do not know the IP address, follow these steps to display it:

• For a Windows NT system, enter the command ipconfig at the DOS prompt.

• For a Windows 95 system, enter the command winipcfg from the Windows Start > Run menu.

• From a UNIX workstation, enter ifconfig -a or look at the /etc/hosts file.

Upgrading Switch Software by Using the Command-line Interface

You can use the CLI to perform a TFTP transfer of the files to the switch.

The procedure that follows includes the commands to address the following issues:

•To avoid a conflict with users accessing the manager software pages during the software upgrade, delete the existing HTML files and disable access to the HTML pages before you upgrade the software.

•Because the switch Flash memory can hold only one software image file, you need to change the name of the current image file to the name of the new file you are copying. You then replace the old file with the new file when you copy it into Flash memory.

Follow these steps to upgrade the switch software by using a TFTP transfer:

Step 1 If your PC or workstation cannot act as a TFTP server, copy the files to a TFTP server to which you have access.

Step 2 You can access the CLI by starting a Telnet session or by connecting to the console port via the RS-232 connector.

To start a Telnet session on your PC or workstation, enter the following command: 

server% telnet switch_ip_address

Step 3 Enter privileged EXEC mode: 

switch> enable 
switch#

Step 4 Display the name of the current (default) image file. The following example shows the current name in italic: 

switch# show boot 
BOOT path-list:    flash:current_image 
Config file:       flash:config.text 
Enable Break:      1 
Manual Boot:       no

Step 5 If there is no file defined in the BOOT path-list, enter dir flash: to display the contents of Flash memory. The file named c2900XL-h-mz_current_version is your current image file.

Step 6 Rename the current image file to the name of the new image. This does not affect the operation of the switch. 

switch# rename flash:current_image flash:new_image 
Source filename [current_image]?  
Destination filename [new_image]?

Step 7 Display the contents of Flash memory to verify the renaming of the file: 

switch# dir flash: 
Directory of flash: 
-rwx      910426 Mar 06 1993 23:47:28  new_image

-rwx       80971   Sep 14 1998 03:10:38  c2900XL-diag-mz-112.0.0.11-SA2 
-rwx        4800   Mar 01 1993 00:04:14  html 
-rwx         159   Jan 01 1970 00:00:34  env_vars 
-rwx        1121   Mar 01 1993 18:46:01  config.text

Step 8 Delete the diagnostics file to make room for the new image.

The diagnostics file has a name in the following format: c2900XL-diag-mz-version_name. The string version_name depends on the switch and software you are running.

Display the diagnostics file: 

switch# dir flash:c2900XL-diag-mz* 
Directory of flash:

-rwx 80971 Sep 14 1998 03:10:38 c2900XL-diag-mz-112.0.0.11-SA2

Delete the diagnostics file: 

Switch# del flash:c2900XL-diag-mz-112.0.0.11-SA2

Delete filename [c2900XL-diag-mz-112.0.0.11-SA2]?

Delete flash:c2900XL-diag-mz-112.0.0.11-SA2? [confirm]

Switch#

Step 9 Enter terminal configuration mode: 

switch# configure terminal 
Enter configuration commands, one per line. End with CNTL/Z.

Step 10 Disable access to the switch HTML pages: 

switch(config)# no IP http server

Step 11 Change the name of the default image file: 

switch(config)# boot system flash:new_image

Step 12 Return to privileged EXEC mode: 

switch(config)# ^Z

Step 13 Verify that the name of the default image file is correct: 

switch# show boot 
BOOT path-list:    flash:new_image 
Config file:       flash:config.text 
Enable Break:      1 
Manual Boot:       no 
HELPER path-list:  
NVRAM/Config file 
buffer size: 32768

Step 14 Use the name of the new image file when you copy it from the TFTP server to the Flash memory: 

switch# copy tftp://server_ip_address//path/new_image flash:new_image 
Source IP address or hostname [server_ip_address]?  
Source filename [path/filename]?  
Destination filename [flash:new_image]?  
Loading /path/filename.bin from server_ip_address (via!) 
[OK - 843975 bytes]

Step 15 Remove the manager software HTML files: 

switch# del flash:html/*

Press the Enter key to confirm the deletion of each file. Do not press any other keys during this process.

Step 16 If you are running IOS Release 11.2(8)SA3 or later, remove the files in the Snmp directory: 

switch# del flash:html/Snmp/*

Press the Enter key to confirm the deletion of each file. Do not press any other keys during this process.

Step 17 If you are running IOS Release 11.2(8)SA2 or earlier, create a directory on the switch Flash memory to be used for the HTML files: 

switch# mkdir flash:html/Snmp

Make sure the "S" in "Snmp" is uppercase.

Step 18 Enter the following command to copy the HTML file from the TFTP server to the switch Flash memory: 

switch# tar /x tftp://server_ip_address//path/filename.tar flash:html

Loading /path/filename.tar from server_ip_address (via!) 
extracting advanced.gif (2648 bytes) 
extracting amber.gif (530 bytes)! 
extracting bar.gif (4156 bytes)! 
extracting cool.gif (530 bytes) 
extracting daytona.gif (1470 bytes) 
extracting duplgnd.gif (639 bytes)! 
. . .

Depending on the TFTP server being used, you might need to enter only one slash (/) after the server_ip_address in the tar command.

Step 19 Enter terminal configuration mode: 

switch# configure terminal 
Enter configuration commands, one per line. End with CNTL/Z.

Step 20 Reenable access to the switch HTTP pages: 

switch(config)# IP http server

Step 21 Return to privileged EXEC mode: 

switch(config)# ^Z

Step 22 Reload the new software with the following command: 

switch# reload 
System configuration has been modified. Save? [yes/no]:y 
Proceed with reload? [confirm]

Step 23 Press Return to confirm the reload.

Your Telnet session ends when the switch resets.
