Check the spanning tree configuration. Blocking ports should be understood and when they show in this
entry it should be the number expected. Otherwise it could be that an unintentional cable loop has
been created that will need to be resolved. Type :
show spanning-tree summary
“show spanning-tree summary” command
Figure 16.
Next, verify that negotiations have happened properly between the FCF and end devices, in this case
the Cisco Nexus 5020 is the FCF. Type :
show flogi database
“show flogi database” command
Figure 17.
At this point the VFC and FC interfaces should be populated in the FLOGI database. This command is
showing the devices that have done a valid FLOGI (fabric login) to the Cisco Nexus switch. The VFC
should show the expected port and node WWN of the CNA being used in the server.
The following command will show the status of the zones that have been put into place. Type:
show
zoneset active
.
This command will show the current activated zoneset and all the participating zones
with their individual members.
