Chapter 11 Troubleshooting VSANs, Domains, and FSPF VSAN Issues Send documentation comments to [email protected] Resolving an Isolated ISL Using Fabric Manager Trunking E ports (TE ports) are similar to E ports except that they carry traffic for multiple VSANs. E ports carry traffic for a single VSAN. Because TE ports carry traffic for multiple VSANs, ISL isolation can affect one or more VSANs. For this reason, on a TE port you must troubleshoot for ISL isolation on each VSAN. To resolve VSAN isolation on a TE port using Fabric Manager, follow these steps: Step 1 Step 2 Step 3 Step 4 Choose Switches > Interfaces > FC Physical and check the FailureCause column on the TE port to verify that you have a trunk problem. Choose Switches > Interfaces > FC Physical and select the Trunk Failures tab to determine the reason for the trunk problem. Correct the problem listed in the FailureCause column. See the "DPVM Config Database Not Activating" section on page 11-14 for domain misconfiguration problems. Choose Switches > Interfaces > FC Physical and use the PortVSAN field to correct the VSAN misconfiguration problems. Repeat this procedure for all isolated VSANs on this TE port. Resolving an Isolated ISL Using the CLI Trunking E ports (TE ports) are similar to E ports except that they carry traffic for multiple VSANs. E ports carry traffic for a single VSAN. Because TE ports carry traffic for multiple VSANs, ISL isolation can affect one or more VSANs. For this reason, on a TE port you must troubleshoot for ISL isolation on each VSAN. To resolve VSAN isolation on a TE port using the CLI, follow these steps: Step 1 Use the show interface command on the TE port to verify that you have an isolated VSAN. switch# show interface fc2/14 fc2/14 is trunking Hardware is Fibre Channel, WWN is 20:4e:00:05:30:00:63:9e Port mode is TE Speed is 2 Gbps vsan is 2 Beacon is turned off Trunk vsans (allowed active) (1-3,5) Trunk vsans (operational) (1-3,5) Trunk vsans (up) (2-3,5) Trunk vsans (isolated) (1) Trunk vsans (initializing) () 475 frames input, 8982 bytes, 0 discards 0 runts, 0 jabber, 0 too long, 0 too short 0 input errors, 0 CRC, 3 invalid transmission words 0 address id, 0 delimiter 0 EOF abort, 0 fragmented, 0 unknown class 514 frames output, 7509 bytes, 16777216 discards Received 30 OLS, 21 LRR, 18 NOS, 53 loop inits The example shows the output of the show interface command with one or more isolated VSANs.
