i am a newbie of MDS.
now I have questions about port-channel.
currently we configure port-channel on the MDS(MDS9513), which contains 4 members....and We also have 3 other port-channel
lasfswcor02# sh interface port-channel 53
port-channel 53 is up
Port description is "uslas-c6296fi-01-b"
Hardware is Fibre Channel
Port WWN is 24:35:00:05:73:e2:5e:40
Admin port mode is F, trunk mode is on
snmp link state traps are enabled
Port mode is F
Port vsan is 520

my questions are as below:
1) how do you know which server is using which port-channel ?
2) how do you know how much traffic / or utilization each port is using?
3) how do you see if the port-group is saturated?
Really appreciate your help
thanks in advance!!!!!

I assume you meant which inteface in the port channel?
They are load balanced, so each server might at any time be using any of the interfaces.
That is one of the benefits of using a port-channel. If these were individual interfaces not
in a port channel, the servers would be distributed round robin. The server would be tied to that
interface, ( which you could see in the show flogi database on the MDS ) and could only use
the bandwidth of that one interface. Also, if that interface goes down, then the server would have
to log back into the fabric over another interface to the MDS.
Use Fabric Manager, Device Manager, Cisco Prime Data Center Network Manager or show interface CLI command.
Use Fabric Manager, Device Manager, or Cisco Prime Data Center Network Manager.
