Release Notes for Cisco Catalyst Blade Switch 3120 for HP, Cisco IOS Release 12.2(50)SE and Later

OL-18270-03

Limitations and Restrictions

Stacking

These are the switch stack limitations:

• When using the logging console global configuration command, low-level messages appear on both

the stack master and the stack member consoles.

The workaround is to use the logging monitor global configuration command to set the severity

level to block the low-level messages on the stack member consoles. (CSCsd79037)

• If a new member switch joins a switch stack within 30 seconds of a command to copy the switch

configuration to the running configuration of the stack master, the new member might not get the

latest running configuration and might not operate properly.

The workaround is to reboot the new member switch. Use the remote command all show run

privileged EXEC command to compare the running configurations of the stack members.

(CSCsf31301)

• When the flash memory of a stack member is almost full, it might take longer to start up than other

member switches. This might cause that switch to miss the stack-master election window. As a

result, the switch might fail to become the stack master even though it has the highest priority.

The workaround is to delete files in the flash memory to create more free space. (CSCsg30073)

• If you enter the show tech-support privileged EXEC command after you enter the remote

command {all | stack-member-number} privileged EXEC command, the complete output does not

appear.

The workaround is to use the session stack-member-number privileged EXEC command.

Device Manager Limitations

These are the device manager limitations:

• When you are prompted to accept the security certificate and you click No, you only see a blank

screen, and the device manager does not start.

The workaround is to click Yes when you are prompted to accept the certificate. (CSCef45718)

• If you launch the device manager from a Firefox web browser, an invalid certificate alert appears.

If you launch the device manager from an Internet Explorer 7.0 browser, a certificate error appears.

The workaround when using Firefox is to either temporarily or permanently accept the certificate.

If you temporarily accept the certificate, close and then reopen the Firefox browser window. If you

permanently accept the certificate, delete the certificate, and then close and restart Firefox:

–

If you are using Firefox version 1.5, choose Tools > Options > Advanced > Security >

View Certificates > Web Sites, select the certificate, and click Delete.

–

If you are using Firefox version 2.0, choose Tools > Options > Advanced > Encryption > View

Certificates > Web Sites, select the certificate, and click Delete.

The workaround when using Internet Explorer is to click Click here for Options in the warning

message, and click Display Blocked Content. Close the browser window, and launch a new session.
