Upgrading the Switch Software
Upgrading the Switch Software
These are the procedures for downloading software. Before downloading software, read this section for
important information:
• “Finding the Software Version and Feature Set” section on page 4
• “Deciding Which Files to Use” section on page 4
• “Upgrading a Switch by Using the Device Manager” section on page 5
• “Upgrading a Switch by Using the CLI” section on page 5
• “Recovering from a Software Failure” section on page 6
Finding the Software Version and Feature Set
The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release.
A subdirectory contains the files needed for web management. The image is stored on the system board
flash device (flash:).
You can use the show version privileged EXEC command to see the software version that is running on
your switch. The second line of the display shows the version.
You can also use the dir filesystem: privileged EXEC command to see the directory names of other
software images that you might have stored in flash memory.
Deciding Which Files to Use
The upgrade procedures in these release notes describe how to perform the upgrade by using a combined
tar file. This filecontainsthe Cisco IOS image file and the filesneeded for the embedded device manager.
You must use the combined tar file to upgrade the switch through the device manager. To upgrade the
switch through the CLI, use the tar file and the archive download-sw privileged EXEC command.
Table 3 lists the filenames for this software release.

Upgrading the Switch Software
Cisco routinely removes old Cisco IOS versions from Cisco.com. See Product Bulletin 2863 for more
information:
http://www.cisco.com/en/US/products/sw/iosswrel/ps5187/prod_bulletin0900aecd80281c0e.html
You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a
host by using the copy flash: tftp: privileged EXEC command.
Note Although you can copy any file on the flash memory to the TFTP server, it is time consuming to copy
all of the HTML files in the tar file. We recommend that you download the tar file from Cisco.com and
archive it on an internal host in your network.
You can also configure the switch as a TFTP server to copy files from one switch to another without
using an external TFTP server by using the tftp-server global configuration command. For more
information about the tftp-server command, see the “Basic File Transfer Services Commands” section
of the Cisco IOS Configuration Fundamentals Command Reference, Release 12.2 at this URL:

Upgrading a Switch by Using the Device Manager
You can upgrade switch software by using the device manager. For detailed instructions, click Help.
Note When using the device manager to upgrade your switch, do not use or close your browser session after
the upgrade process begins. Wait until after the upgrade process completes.
Upgrading a Switch by Using the CLI
This procedure is for copying the combined tar file to the switch. You copy the file to the switch from a
TFTP server and extract the files. You can download an image file and replace or keep the current image.
To download software, follow these steps:
Step 1 Use Table 3 on page 4 to identify the file that you want to download.
Step 2 Download the software image file. If you have a SmartNet support contract, go to this URL, and log in
to download the appropriate files:
http://www.cisco.com/kobayashi/sw-center/sw-lan.shtml
Step 3 Copy the image to the appropriate TFTP directory on the workstation, and make sure that the TFTP
server is properly configured.
For more information, see Appendix B in the software configuration guide for this release.
Step 4 Log into the switch through the console port or a Telnet session.

Installation Notes
Step 5 (Optional) Ensure that you have IP connectivity to the TFTP server by entering this privileged EXEC
Step 6 Download the image file from the TFTP server to the switch. If you are installing the same version of
command:
Switch# ping
For more information about assigning an IP address and default gateway to the switch, see the software
configuration guide for this release.
software that is currently on the switch, overwrite the current image by entering this privileged EXEC
command:
Switch# archive download-sw /overwrite /reload
tftp:[[//
The /overwrite option overwrites the software image in flash memory with the downloaded one.
The /reload option reloads the system after downloading the image unless the configuration has been
changed and not saved.
For //location, specify the IP address of the TFTP server.
For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory
and image names are case sensitive.
This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite
the image on the switch:
Switch# archive download-sw /overwrite
tftp://198.30.20.19/c3750-ipservices-tar.122-35.SE.tar
tftp-server-address
location]/directory]/image-name
.tar
You can also download the image file from the TFTP server to the switch and keep the current image by
replacing the /overwrite option with the /leave-old-sw option.
Recovering from a Software Failure
For additional recovery procedures, see the “Troubleshooting” chapter in the software configuration
guide for this release.
Installation Notes
You can assign IP information to your switch by using these methods:
• The Express Setup program or the HP Onboard Administrator program described in the getting
started guide.
• The CLI-based setup program, as described in the hardware installation guide.
• The DHCP-based autoconfiguration, as described in the software configuration guide.
• Manually assigning an IP address, as described in the software configuration guide.

Limitations and Restrictions
You should review this section before you begin working with the switch. These are known limitations
that will not be fixed, and there is not always a workaround. Some features might not work as
documented, and some features could be affected by recent changes to the switch hardware or software.
This section contains these limitations:
• “Cisco IOS Limitations” section on page 7
• “Device Manager Limitations” section on page 11
Cisco IOS Limitations
These limitations apply to the switch:
• “Configuration” section on page 7
• “Ethernet” section on page 8
• “IP” section on page 8
• “IP Telephony” section on page 8
• “MAC Addressing Multicasting” section on page 9
• “MAC Addressing Multicasting” section on page 9
• “QoS” section on page 10
• “SPAN and RSPAN” section on page 10
• “Trunking” section on page 10
• “VLAN” section on page 11
Limitations and Restrictions
Configuration
These are the configuration limitations:
• A static IP address might be removed when the previously acquired DHCP IP address lease expires.
This problem occurs under these conditions:
–
When the switch is booted without a configuration (no config.text file in flash memory).
–
When the switch is connected to a DHCP server that is configured to give an address to it (the
dynamic IP address is assigned to VLAN 1).
–
When an IP address is configured on VLAN 1 before the dynamic address lease assigned to
VLAN 1 expires.
The workaround is to reconfigure the static IP address. (CSCea71176 and CSCdz11708)
• When connected to some third-party devices that send early preambles, a switch port operating at
100 Mbps full duplex or 100 Mbps half duplex might bounce the line protocol up and down. The
problem is observed only when the switch is receiving frames.
The workaround is to configure the port for 10 Mbps and half duplex or to connect a hub or a
nonaffected device to the switch. (CSCed39091)

Limitations and Restrictions
Ethernet
• When port security is enabled on an interface in restricted mode and the switchport block unicast
interface command has been entered on that interface, MAC addresses are incorrectly forwarded
when they should be blocked
The workaround is to enter the no switchport block unicast interface configuration command on
that specific interface. (CSCee93822)
• A traceback error occurs if a crypto key is generated after an SSL client session.
There is no workaround. This is a cosmetic error and does not affect the functionality of the switch.
(CSCef59331)
This is the Ethernet limitation:
• Traffic on EtherChannel ports is not perfectly load-balanced. Egress traffic on EtherChannel ports
are distributed to member ports on load balance configuration and traffic characteristics like MAC
or IP address. More than one traffic stream might map to same member ports, based on hashing
results calculated by the ASIC.
If this happens, traffic distribution is uneven on EtherChannel ports.
Changing the load balance distribution method or changing the number of ports in the EtherChannel
can resolve this problem. Use any of these workarounds to improve EtherChannel load balancing:
–
for random source-ip and dest-ip traffic, configure load balance method as src-dst-ip
–
for incrementing source-ip traffic, configure load balance method as src-ip
–
for incrementing dest-ip traffic, configure load balance method as dst-ip
–
Configure the number of ports in the EtherChannel so that the number is equal to a power of 2
(for example, 2, 4, or 8)
For example, with load balance configured as dst-ip with 150 distinct incrementing destination IP
addresses, and the number of ports in the EtherChannel set to either 2, 4, or 8, load distribution is
optimal. (CSCeh81991)
IP
IP Telephony
Release Notes for the Cisco Catalyst Blade Switch 3040 for FSC, Cisco IOS Release 12.2(35)SE
8
This is the IP limitation:
When the rate of received DHCP requests exceeds 2,000 packets per minute for a long time, the response
time might be slow when you are using the console. The workaround is to use rate limiting on DHCP
traffic to prevent a denial of service attack from occurring. (CSCeb59166)
This is the IP telephony limitation:
After you change the access VLAN on a port that has IEEE 802.1x enabled, the IP phone address is
removed. Because learning is restricted on IEEE 802.1x-capable ports, it takes approximately 30
seconds before the address is relearned. No workaround is necessary. This limitation is unlikely to affect
the Cisco Catalyst Blade Switch 3040 for FSC because IP phones are not usually connected to the switch
uplink ports. (CSCea85312)
