1) is there any command to see the WWN of all the interfaces in the FC switch ? I am using sh int at the moment
Try command: show flogi database It lists the wwpn and fcid of each attached device on the MDs.
2) it is said that FCID is use to locate other switches/nodes in the fabric - what is the command to see which FCID is associated to which interface ? i use show fcdomain fcid persistent but i am not able to see the fcid of adjacent switch connected through trunk link and its connected devices even though i can see the device through show zone active
Try commands: "show topology" - it lists all TE/portchannels and switch names attached to opposite end of the cable.
"show fcs ie" - shows the MDS switch names and IP address for each VSAN
3) in show run i am seeing
what does dynamic means ?
Does that means any wwn that flogin into the switch will be display here ?
Dynamic means the MDS assigned the fcid when the device was plugged in. If persistent fcid is enabled, the device will maintain the dynamic fcid if moved to a different port interface. Static means the fcid was assigned by the SAN admin. Dynamic fcids not in use can be purged on a per VSAN basis with the purge command. More detail can be found in MDS configuration guide for the NX-OS you are using
