Interfaces in a SAN Port Channel

You can add or remove a physical Fibre Channel interface (or a range of interfaces) to an existing SAN port
channel. The compatible parameters on the configuration are mapped to the SAN port channel. Adding an
interface to a SAN port channel increases the channel size and bandwidth of the SAN port channel. Removing
an interface from a SAN port channel decreases the channel size and bandwidth of the SAN port channel.
Virtual Fibre Channel interfaces cannot be added to SAN port channels.
Note

About Interface Addition to a SAN Port Channel

You can add a physical interface (or a range of interfaces) to an existing SAN port channel. The compatible
parameters on the configuration are mapped to the SAN port channel. Adding an interface to a SAN port
channel increases the channel size and bandwidth of the SAN port channel.
After the members are 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.

Compatibility Check

A compatibility check ensures that the same parameter settings are used in all physical ports in the channel.
Otherwise, they cannot become part of a SAN port channel. The compatibility check is performed before a
port is added to the SAN port channel.
The check ensures that the following parameters and settings match at both ends of a SAN port channel:
• Capability parameters (type of interface, Fibre Channel at both ends).
• Administrative compatibility parameters (speed, mode, port VSAN, allowed VSAN, and port security).
• Operational parameters (speed and remote switch's WWN).
A port addition procedure fails if the capability and administrative parameters in the remote switch are
incompatible with the capability and administrative parameters in the local switch. If the compatibility check
is successful, the interfaces are operational and the corresponding compatibility parameter settings apply to
these interfaces.
