The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the Cisco NX-OS Fibre Channel, virtual Fibre Channel, and Fibre Channel over Ethernet (FCoE) commands that begin with P.
To force a shutdown of a tracked port, use the port-track force-shut command. To reenable the port tracking, use the no form of this command.
port-track force-shut
no port-track force-shut
This command has no arguments or keywords.
None
Interface configuration mode

4.0(0)N1(1a) |

Use the port-track force-shut command to keep the linked port down, even though the tracked port comes back up. You must explicitly bring the port up when required by using the no port-track force-shut command.
This example shows how to force the shutdown of an interface and the interfaces that it is tracking:
switch(config)# interface fc 2/2
switch(config-if)# no port-track force-shut
To enable port tracking for specific interfaces, use the port-track interface command. To disable this feature, use the no form of this command.
port-track interface {fc slot/port | san-port-channel port} [vsan vsan-id]
no port-track interface {fc slot/port | san-port-channel port} [vsan vsan-id]
None
Interface configuration mode

4.0(0)N1(1a) |
This command was introduced. |
When the port that an interface is tracking goes down, the interface also goes down. When the tracked port comes back up, the linked interface also comes back up. Use the port-track force-shut command to keep the linked interface down.
This example shows how to enable port tracking for specific interfaces:
switch(config)# interface fc 2/3
switch(config-if)# port-track interface san-port-channel 2
To purge persistent FCIDs, use the purge fcdomain fcid command.
purge fcdomain fcid vsan vsan-id
vsan vsan-id |
Indicates that FCIDs are to be purged for a VSAN ID. The range is from 1 to 4093. |
None
EXEC mode

4.0(0)N1(1a) |
This command was introduced. |
This example shows how to purge all dynamic, unused FCIDs in VSAN 4:
switch# purge fcdomain fcid vsan 4
This example shows how to purge all dynamic, unused FCIDs in VSANs 4, 5, and 6:
switch# purge fcdomain fcid vsan 4-6
