Chapter 14 Configuring SAN Port Channels
Interfaces in a SAN Port Channel
Step 5 Check the Delete Port Channel If Empty check box to delete this port channel.
Step 6 Click Finish to save any modifications or click Cancel to discard any changes.
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.
Note Virtual Fibre Channel interfaces cannot be added to SAN port channels.
This section describes interface configuration for a SAN port channel and includes the following topics:
• About Interface Addition to a SAN Port Channel, page 14-12
• Adding an Interface to a SAN Port Channel, page 14-13
• Forcing an Interface Addition, page 14-14
• About Interface Deletion from a SAN Port Channel, page 14-14

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).
