Configuring SAN Port Channels
Table 14: Channel Group Configuration Differences
On Mode
No protocol is exchanged.
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 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.

Configuring SAN Port Channels
Active Mode
A port channel protocol negotiation is performed with
the peer ports.
Moves interfaces to the isolated 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.
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 global 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.
Configures the Active mode.
Reverts to the default On mode.
