In the above example, the TE port is carrying traffic for VSANs 1 and 333. This is an example of a
working TE port. There are no isolated VSANs in the list.
The following example shows the output of the show interface command, if one or more VSANs are
isolated:
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)
Trunk vsans (up)
Trunk vsans (isolated)
Trunk vsans (initializing)
In the above example, the TE port has one VSAN isolated. The reason for VSAN isolation can be
checked using the following command:
switch# sh interface fc2/14 trunk vsan 1
The command provides the same messages given by the show interface, in case of E port isolation. For
example:
switch# sh interface fc2/14 trunk vsan 1
fc2/15 is trunking
Vsan 1 is down (Isolation due to zone merge failure)
This output shows that VSAN 1 is isolated because of a zone merge error.
An alternative way to determine the cause of VSAN isolation, is to issue the following command:
switch#show port internal info interface fc2/14
The last few linst provide a description of the reason for VSAN isolation, for all the isolated VSANs.
switch# show port internal info int fc2/14
fc2/14 - if_index: 0x0109C000, phy_port_index: 0x3c
