Modifications Since Release 11.2(8.1)SA6
Modifications Since Release 11.2(8.1)SA6
This section describes new features and caveats that have been resolved since IOS
Release 11.2(8.1)SA6.
•
LED indications for power-on self-test (POST) failures are now different than in IOS Release
11.2(8.1)SA6. If a port fails a test, the port LED and the system LED turn amber and remain amber.
In previous releases, only LEDs of failed linked ports remained amber.
•
The CLI show post command has been added. You can use this command to determine if a switch
or port has passed POST.
•
When a 4-MB Catalyst 2900 XL switch is added to a cluster, reloading the switch by a soft reset or
power recycling no longer brings down the switch. (CSCdm94877)
•
When a port is changed from a multi-VLAN port to an access port, there is no longer a possible
loss of connectivity. (CSCdm72514)
•
The privileged EXEC mode config clock summer-time recurring command no longer resets the
switch. (CSCdm94936)
•
When using the GigaStack GBIC with a 3500 XL switch or 2900 XL modular switch and IOS
Release 11.2(8.1)SA6, you could experience a problem with traffic flow in one direction when you
insert a cable. This potential problem has been resolved. (CSCdm40538)
•
The configure overwrite-network command no longer overwrites the configuration file with
gibberish. (CSCdm24149)
•
When upgrading a switch from the CVSM System page, the switch no longer renames the existing
filename when Retain Current IOS Image File Name field is selected. (CSCdm32685)
•
All GBIC ports in a Gigastack are now able to transmit and receive packets after a reset.
(CSCdp40480)
•
Unpredictable delays no longer occur during STP root election in redundant networks.
(CSCdp45829)
•
When Cisco Group Management Protocol (CGMP) is enabled, the Catalyst 2900 XL and Catalyst
3500 XL switches now correctly forward IGMP host inquiries. When CGMP is disabled, ports are
no longer flooded. (CSCdp24818, CSCdp20721)

Limitations and Restrictions
Limitations and Restrictions
This section should be reviewed before you begin working with the switches. Some features might not
work as documented, and some features could be affected by recent changes to the switch hardware or
software.
Connecting to the 600W Cisco Redundant Power System
The following restrictions apply to using the 600W Cisco Redundant Power System (RPS) with a
Catalyst 2900 XL switch:
•
Do not connect a switch power cord to an AC outlet if the switch is also connected to a powered-up
RPS.
•
The switches do not support the fully-redundant configuration described in the Cisco RPS
Hardware Installation Guide. The redundant with reboot configuration is not recommended with
Catalyst 2900 XL switches.
The Cisco RPS can provide a quasi-redundant power source for four external devices that use up to
150W DC each. You can use a one-to-one cable (one connector at each cable end) to connect four
external devices to the four DC output power modules. The power source is quasi-redundant because
there are two AC input power modules for the Cisco RPS and one DC output power module for each
external device. The AC input to the Cisco RPS is fully redundant, but the DC output to the external
devices is not.
Hot-Swapping Not Supported for ATM and Gigabit Ethernet Modules
A Catalyst 2900 XL switch must be turned off before you can insert one of the following modules:
•
Catalyst 2900 series XL 1000BaseX modules
•
Catalyst 2900 series XL ATM modules
Port Configuration Conflicts
Certain combinations of port features create configuration conflicts (see Table 4). For example, the
network port floods all unknown unicast and multicast packets to a port; therefore, port security, which
limits traffic on a port, cannot be enabled on the network port. If you try to enable incompatible features,
CVSM issues a warning message and prevents you from making the change. Reload the page to refresh
CVSM. In Table 4, No means that the two referenced features are not compatible.

IEEE 802.1Q Configuration Considerations
IEEE 802.Q trunks impose some limitations on the trunking strategy for a network. The following
restrictions apply to IEEE 802.1Q trunks:
•
Make sure the native VLAN for an IEEE 802.1Q trunk is the same on both ends of the trunk link.
If the native VLAN on one end of the trunk is different from the native VLAN on the other end,
spanning-tree loops might result.
•
Disabling STP on the native VLAN of an IEEE 802.1Q trunk without disabling STP on every
VLAN in the network can potentially cause STP loops. We recommend that you either leave STP
enabled on the native VLAN of an IEEE 802.1Q trunk or disable STP on every VLAN in the
network. Make sure your network is loop-free before disabling STP.
Spanning-Tree Maximum Age Command
The range of seconds for the span-tree max-age command is now 6 to 200 seconds. If you use this
command in a previous release to set a value greater than this new range and then upgrade your software
to IOS Release 11.2(8.1)SA6 or later, the switch sets this value to the default: 20 seconds for IEEE STP,
15 seconds for DEC STP, and 10 seconds for IBM STP.
Compatibility with the CiscoWorks2000 RME Suite
When using the Software Image Management (SWIM) application in the Resource Manager Essentials
(RME) suite of CiscoWorks2000 product family to perform automated system software and boot loader
upgrades, Catalyst 2900 series XL switches require IOS Release ll.2(8)SA4 or later and RME version
2.1 or 2.2.

Upgrading to a New Software Release
Upgrading to a New Software Release
This section describes the procedure for upgrading your switch software by using the IOS
command-line interface (CLI).
If you are running IOS Release 11.2(8)SA3 or later, we recommend that you upgrade the switch by
using the web-based CVSM. Instructions for upgrading through CVSM are in the Catalyst 2900 Series
XL Installation and Configuration Guide, or, for this IOS release, the Cisco IOS Desktop Switching
Software Configuration Guide.
Note
You cannot use the web-based interface to upgrade a switch running IOS Release
11.2(8)SA2 or previous releases. Use the CLI to perform the upgrade in such cases.
The CLI upgrade procedure consists of the following major steps:
Step 1
Downloading the combined .tar file from CCO. This file contains the IOS image and the HTML files.
The tar command extracts the IOS image and the HTML files from the combined .tar file during the
TFTP copy to the switch.
Step 2
If necessary, downloading the TFTP server application to copy the switch software from your PC to
the switch.
Step 3
Using the CLI or CVSM to upgrade your switch to the new software.
Which Files to Use
Review Table 5 and Table 6 before you download the software. Table 5 describes the file extensions and
what they mean for the upgrade procedure. In general, it is easier to upgrade the switch software by
using a combined .tar file that contains the HTML files and the IOS image. The upgrade procedures in
these release notes describe how to use a combined .tar file, and you must use a combined .tar file to
upgrade a switch through the switch HTML interfaces.
Table 6 lists the file names for the 4-MB original edition software. Original edition software is
Enterprise Edition Software that runs on the following 4-MB switch models: WS-C2908-XL,
WS-C2924-XL, WS-C2924C-XL, or WS-C2916M-XL. Original edition software does not support
TACACS+, STP UplinkFast, or NTP. This software enables the switch to act as a cluster member switch
only, not a commander switch.
Table 5
Possible Extensions for IOS Software Files
Extension Description
.tar
.bin
A compacted file from which you can extract files by using the tar command. There are two types of .tar files:
•
A combined .tar file that contains both the IOS image file and the HTML files. You can upgrade the switch
software with this file from the CLI or from the CVSM System page.
•
An HTML .tar file that has the letters HTML in its name and contains just the HTML files for an IOS release.
You can upgrade the switch software from the CLI with this HTML file and the IOS image file.
The IOS image file that you can copy to the switch through TFTP.

Downloading the New Software
Follow these steps to download a new version of IOS 11.2(8.6)SA6 software and, if necessary, the TFTP
server application.
Step 1
Use Table 5 to Table 6 to identify the files that you want to download.
Note
Step 2
We recommend that you download the combined .tar file that contains the image
file and the HTML files. The procedures in these release notes are for upgrading
a switch by using a combined .tar file, and the web-based CVSM interface is
designed to upgrade a switch by using this combined file.
Download files from the following locations:
•
Registered users:
Enter the following URL in your browser Go To or Location field:
http://www.cisco.com/cgi-bin/tablebuild.pl/cat2900XL
•
Nonregistered users:
http://www.cisco.com/pcgi-bin/tablebuild.pl/cat2900XL
Step 3
Download the IOS file or files.
Step 4
Download the TFTP server from this URL, if necessary. The readme.txt file describes how to
download the TFTP server.
After you have downloaded the correct file to your PC or workstation, you can use the CLI to perform
a TFTP transfer of the file or files to the switch.
Upgrading 4-MB Catalyst 2900 Series XL Switches
This procedure is for upgrading the 4-MB switches that run IOS Release 11.2(8.2)SA6 original edition
software. The 4-MB models that run the original edition software are WS-C2908-XL, WS-C2924-XL,
WS-C2924C-XL, and WS-C2916M-XL. You upgrade the switches by extracting the IOS image file and
the HTML files from a combined .tar file. You copy the files to the switch from a TFTP server and
extract the files by entering the tar command.

Upgrading to a New Software Release
Note
If you want to copy the IOS image file or HTML files separately to the switch, follow the
upgrade procedure in the release notes that came with your switch, or refer to CCO for the
Catalyst 2900 series XL release notes for IOS Release 11.2(8)SA4.
If you are unsure whether your switch has 4 MB or 8 MB of memory, you can verify memory capacity
at Step 4.
Follow these steps to upgrade the switch software by using the tar command and a TFTP transfer:
Step 1
If your PC or workstation cannot act as a TFTP server, copy the file to a TFTP server to which you
have access.
Step 2
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

Step 24
After the switch reboots, you can use Telnet to go back into the switch and enter the show version
command in privileged EXEC mode to verify the upgrade procedure.
Current Caveats
This section describes possible unexpected activity by IOS Release 11.2(8.6)SA6.
•
When you try to access a switch by entering the IP address in the location field while using CVSM,
the switch displays the Cisco Access page for the new switch. However, you cannot access CVSM
for the new switch from this page. The switch refreshes the Cisco Access page without displaying
the switch home page.
The workaround is to start a new browser session and enter the IP address of the new switch in the
Location field of the new browser session. (CSCdm27401)
•
If you use Telnet or a browser to access a member switch without an IP address from the CVSM
CDP page, the switch starts a session with the command switch.
The workaround for Telnet is to first display the cluster-member number by entering the privileged
EXEC command show cluster member. Note the number of the member you want to access, and
then Telnet to the switch by entering the following command: rcommand switch_number.
The workaround for the browser is to start Cluster Management from the switch home page and
start Cluster Manager. Right-click on the chassis of the switch that you want to access, and select
Switch Manager. (CSCdm34868)
•
The Device Report and Bandwidth Graph menu items for candidate switches without IP addresses
do not work.
The workaround is to add candidates to the cluster and then right-click the device and select Device
Report or Bandwidth Graph from the pop-up menu. (CSCdm31724)
•
The Link Graph between members and non-members does not work.
The workaround is to display the Device Report for the member switch, select Port Information
from the drop-down menu in the right corner of the page, and click the appropriate port. Click
Graph. (CSCdm32226)
•
Device reports and graphs give “SNMP Unavailable” messages.
First make sure that the switch is reachable via the network and that the SNMP agent is enabled.
Also verify that you are using the correct community string. There should be only one read-only
SNMP community string. If you change the community string while using cluster manager or
CVSM, you must reload your browser to display the changes. (CSCdm32367)
•
Links between members sometimes do not display in Cluster Builder or Cluster View.
The workaround is to display the Device Links Report from the Cluster Builder window.

•
In Internet Explorer 5.0, the tab key does not work properly. It does not highlight the editable fields
as it should.
Use the mouse to click on the field, or use Netscape 4.5, Netscape 4.5.1, or Internet Explorer 4.01.
(CSCdm24761)
•
If you enter the interface configuration mode no ip address command to remove the IP address
from a member switch, it disables the switch IP protocol stack.
The workaround is to enter the Exec mode clear ip address vlan 1 command instead.
(CSCdm39373)
•
Network Address Translation (NAT) commands are added to the configuration file of a command
switch when a cluster is created.
No workaround is necessary, but the commands should not be removed. (CSCdm39380)
