RBridge ID is duplicated
Switches with the same RBridge ID cannot coexist in the same VCS Fabric cluster. Any attempt to add
a switch with the same RBridge ID as an existing cluster switch will fail. The ISL between the two
switches will not be formed; it will be segmented.
1. On the new switch, enter the show vcs command to determine the RBridge ID.
switch2# show vcs
Config Mode : Local-Only
VCS ID : 1
Total Number of Nodes : 1
Rbridge-Id WWN Management IP Status HostName
-------------------------------------------------------------------
22 >10:00:00:05:33:13:B3:5A* 10.24.84.41 Online
2. On any switch in the functioning VCS Fabric cluster, enter the show vcs command to display the
RBridge IDs for all the switches in the cluster.
switch1# show vcs
Config Mode : Local-Only
VCS ID : 1
Total Number of Nodes : 2
Rbridge-Id WWN Management IP Status HostName
-------------------------------------------------------------------
60 10:00:00:05:33:5F:EA:A4 10.24.81.65 Online switch1
66 >10:00:00:05:33:67:26:78* 10.24.81.66 Online switch 2
3. If the new switch has the same RBridge ID as any switch in the existing cluster, on the new switch,
in privileged EXEC mode, enter the vcs rbridge-id command to change the RBridge ID to a unique
value.
switch2# vcs rbridge-id 77
SNMP MIBs report incorrect values
If SNMP MIBs report incorrect values, complete the following steps.
1. Ensure you are using a supported MIB browser.
2. Ensure that the issue is seen consistently.
3. Ensure that the SNMP configuration is correct.
4. If the MIB browser is supported, the SNMP configuration is correct, and you still see the issue
consistently, contact your switch support provider.
SNMP traps are missing
If SNMP traps are missing, complete the following procedure.
1. Ensure that the correct SNMP configuration is enabled. Refer to SNMP configuration on page 139
for details.
2. Ensure that the SNMP host is reachable.
3. If the problem still persists, contact your switch support provider.
As a workaround, set a trap configuration for syslog messages.
Telnet operation into the switch fails
Assuming a correct IP address and correct login credentials, failure to access the switch using Telnet
could be for one of the following reasons:
