About San Port Channel Deletion; Configuring Active Mode San Port Channel - Cisco AP775A - Nexus Converged Network Switch 5010 Configuration Manual

Configuring SAN Port Channels
On Mode
When you add or modify a port channel member port
configuration, you must explicitly disable (shut) and
enable (no shut) the port channel member ports at
either end.
Port initialization is not synchronized.
All misconfigurations are not detected as no protocol
is exchanged.
Transitions misconfigured ports to the suspended
state. You must explicitly disable (shut) and enable
(no shut) the member ports at either end.
This is the default mode.

About SAN Port Channel Deletion

When you delete the SAN port channel, the corresponding channel membership is also deleted. All interfaces
in the deleted SAN port channel convert to individual physical links. After the SAN port channel is removed,
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.
If you delete the SAN port channel for one port, then the individual ports within the deleted SAN port channel
retain the compatibility parameter settings (speed, mode, port VSAN, allowed VSAN, and port security). You
can explicitly change those settings as required.
• If you use the default On mode to avoid inconsistent states across switches and to maintain consistency
• If you use the Active mode, then the port channel ports automatically recover from the deletion.

across switches, then the ports shut down. You must explicitly enable those ports again.

Active Mode
When you add or modify a port channel interface, the
SAN port channel automatically recovers.
There is synchronized startup of all ports in a channel
across peer switches.
Consistently detect misconfigurations using a port
channel protocol.
Transitions misconfigured ports to the isolated state
to correct the misconfiguration. Once you correct the
misconfiguration, the protocol ensures automatic
recovery.
You must explicitly configure this mode.
Purpose
Enters configuration mode.
Configures the specified port channel using the
default On mode. The SAN port channel
number is in the range of 1 to 256.
