MDS-9132T - PWWN and FCID

Hi all

 

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

 

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

 

3) in show run i am seeing

fcdomain fcid database
  vsan 1 wwn 50:06:0e:80:12:54:09:00 fcid 0x9e0000 dynamic
  vsan 110 wwn 50:06:0e:80:12:54:09:00 fcid 0x890000 dynamic
  vsan 110 wwn 50:06:0e:80:12:54:09:10 fcid 0x890020 dynamic
  vsan 110 wwn 50:06:0e:80:12:54:09:21 fcid 0x890040 dynamic
  vsan 110 wwn 21:00:f4:e9:d4:0e:03:a0 fcid 0x890001 dynamic

what does dynamic means ?

Does that means any wwn that flogin into the switch will be display here ?

 

Thank you

Try command:  show flogi database     It lists the wwpn and fcid of each attached device on the MDs.

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

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
