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.

Archiving Software Images

Before upgrading your switch software, make sure that you have archived copies of the current Cisco

IOS release and the Cisco IOS release to which you are upgrading. You should keep these archived

images until you have upgraded all devices in the network to the new Cisco IOS image and until you

have verified that the new Cisco IOS image works properly in your network.

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

command:

Switch# ping

tftp-server-address

For more information about assigning an IP address and default gateway to the switch, see the software

configuration guide for this release.

Step 6 Download the image file from the TFTP server to the switch. If you are installing the same version of

software that is currently on the switch, overwrite the current image by entering this privileged EXEC

command:

Switch# archive download-sw /overwrite /reload

tftp:[[//

location

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.

New Software Features

There are no new software features in this release.

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

• “QoS” section on page 10

• “SPAN and RSPAN” section on page 10

• “Trunking” section on page 10

• “VLAN” section on page 11

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)

Release Notes for the Cisco Catalyst Blade Switch 3040 for FSC, Cisco IOS Release 12.2(35)SE

OL-12212-01

Limitations and Restrictions

• 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)

Ethernet

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)

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)

IP Telephony

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)
