Cisco Nexus 5000 Series - Configuring Active Mode SAN Port Channel

A F port channel is supported only in Active Mode.Note
The table below compares On and Active modes.

Active ModeOn Mode
A port channel protocol negotiation is performed with
the peer ports.
No protocol is exchanged.
Moves interfaces to the isolated state if its operational
values are incompatible with the SAN port channel.
Moves interfaces to the suspended state if its
operational values are incompatible with the SAN
port channel.
When you add or modify a port channel interface, the
SAN port channel automatically recovers.
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.
There is synchronized startup of all ports in a channel
across peer switches.
Port initialization is not synchronized.
Consistently detect misconfigurations using a port
channel protocol.
All misconfigurations are not detected as no protocol
is exchanged.
Transitions misconfigured ports to the isolated state
to correct the misconfiguration. Once you correct the
misconfiguration, the protocol ensures automatic
recovery.
Transitions misconfigured ports to the suspended
state. You must explicitly disable (shut) and enable
(no shut) the member ports at either end.
You must explicitly configure this mode.This is the default mode.
