P Commands

This chapter describes the Cisco NX-OS Fibre Channel, virtual Fibre Channel, and Fibre Channel over Ethernet (FCoE) commands that begin with P.

port-track force-shut

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

Syntax Description

This command was introduced.


Usage Guidelines

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.

Examples

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
