You can view specific information about existing SAN port channels at any time from EXEC mode. The following show commands provide further details on existing SAN port channels.
The show san-port-channel summary command displays a summary of SAN port channels within the switch. A one-line summary of each SAN port channel provides the administrative state, the operational state, the number of attached and active interfaces (up), and the first operational port (FOP), which is the primary operational interface selected in the SAN port channel to carry control-plane traffic (no load-balancing). The FOP is the first port that comes up in a SAN port channel and can change if the port goes down. The FOP is also identified by an asterisk ( * ).
To display VSAN configuration information, perform one of the following tasks:
Example of Verification Commands
The following example shows how to display a summary of SAN port channel information:
switch# show san-port-channel summary
------------------------------------------------------------------------------
Interface Total Ports Oper Ports First Oper Port
------------------------------------------------------------------------------
san-port-channel 7 2 0 --
san-port-channel 8 2 0 --
san-port-channel 9 2 2
The following example shows how to display SAN port channel consistency:
switch# show san-port-channel consistency
Database is consistent
The following example shows how to display details of the used and unused port channel numbers:
switch# show san-port-channel usage
Totally 3 port-channel numbers used
===================================
Used : 77 - 79
Unused: 1 - 76 , 80 - 256
Autocreated SAN port channels are indicated explicitly to help differentiate them from the manually created SAN port channels. The following example shows how to display an autocreated port channel:
switch# show interface fc2/1
fc2/1 is trunking
Hardware is Fibre Channel, FCOT is short wave laser
Port WWN is 20:0a:00:0b:5f:3b:fe:80
...
Receive data field Size is 2112
Beacon is turned off
Port-channel auto creation is enabled
Belongs to port-channel 123
