Important Notes
•
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)

In a mixed stack which consists of Catalyst 3750 switches along with Catalyst 3750-E switches,
when the stack ring is congested with approximately 40 Gb/s of traffic, some of the local traffic from
one port to another on a Catalyst 3750-E member might be dropped.

The workaround is to avoid traffic congestion on the stack ring. (CSCsd87538)

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.

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.
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)

In a mixed stack of Catalyst 3750 switches and Catalyst 3750-E switches, when the stack reloads,
the Catalyst 3750-E might not become stack master, even it has a higher switch priority set.
the Catalyst 3750-E might not become stack master, even it has a higher switch priority set.
The workaround is to check the flash. If it contains many files, remove the unnecessary ones. Check
the lost and found directory in flash and if there are many files, delete them. To check the number
of files use the fsck flash: command. (CSCsi69447)

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 launch.
