Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)

After the members are forcefully added, regardless of the mode (Active and On) used, the ports at either end
are gracefully brought down, indicating that no frames are lost when the interface is going down.
To force the addition of a port to a SAN port channel, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configuration terminal
Step 1
Enters configuration mode for the specified
interface.
switch(config)# interface type slot/port
Step 2
Forces the addition of the interface into the
specified channel group. The E port is shut down.
switch(config-if)# channel-group
channel-number force
Step 3
About Interface Deletion from a SAN Port Channel
When a physical interface is deleted from the SAN port channel, the channel membership is automatically
updated. If the deleted interface is the last operational interface, then the port channel status is changed to a
down state. Deleting an interface from a SAN port channel decreases the channel size and bandwidth of the
SAN port channel.
• If you use the default On mode to avoid inconsistent states across switches and to maintain consistency
across switches, then the ports shut down. You must explicitly enable those ports again.
• If you use the Active mode, then the port channel ports automatically recover from the deletion.
After the members are deleted, regardless of the mode (Active and On) used, the ports at either end are
gracefully brought down, indicating that no frames are lost when the interface is going down.
Deleting an Interface from a SAN Port Channel
To delete a physical interface (or a range of physical interfaces) from a SAN port channel, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode for the specified
interface.
switch(config)# interface type slot/port
Step 1
Deletes the physical Fibre Channel interface from
the specified channel group.
switch(config-if)# no channel-group
channel-number
Step 2
SAN Port Channel Protocol
The switch software provides robust error detection and synchronization capabilities. You can manually
configure channel groups, or they can be automatically created. In both cases, the channel groups have the
same capability and configurational parameters. Any change in configuration applied to the associated SAN
port channel interface is propagated to all members of the channel group.
