Limitations and Restrictions
Stacking
• 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)
• The error message %DOT1X_SWITCH-5-ERR_VLAN_NOT_FOUND might appear for a switch stack under
these conditions:
– IEEE 802.1 is enabled.
– A supplicant is authenticated on at least one port.
– A new member joins a switch stack.
You can use one of these workarounds:
– Enter the shutdown and the no shutdown interface configuration commands to reset the port.
– Remove and reconfigure the VLAN. (CSCsi26444)
• When you use the switch renumber global configuration command to renumber a member switch
in a switch stack and then reload the switch, the internal server-facing ports do not have the required
default of spanning-tree portfast enabled.
The workaround is to apply the switch provision configuration before you reboot the switch.
Enter both the switch current-stack-member-number renumber new-stack-member-number and the
switch stack-member-number provision type global configuration commands, and reload the
switch. (CSCsl63862)
• 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.
(CSCsz38090)
VLANs
• When the domain is authorized in the guest VLAN on a member switch port without link loss and
an Extensible Authentication Protocol over LAN (EAPOL) is sent to an IEEE 802.1x supplicant to
authenticate, the authentication fails. This problem happens intermittently with certain stacking
configurations and only occurs on the member switches.
The workaround is to enter the shut and no shut interface configuration commands on the port to
reset the authentication status. (CSCsf98557)
