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 PortChannel. The compatibility check is performed
before a port is added to the PortChannel.
The check ensures that the following parameters and settings match at both ends of a PortChannel:
•
•
•
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.

Suspended and Isolated States

If the operational parameters are incompatible, the compatibility check fails and the interface is placed
in a suspended or isolated state based on the configured mode:
•
•
See the

Adding an Interface to a PortChannel

To add an interface or range of interfaces to a PortChannel using Fabric Manager, follow these steps:
Expand ISLs and then select Port Channels in the Physical Attributes pane.
Step 1
You see the PortChannels configured in the Information pane (see
Cisco MDS 9000 Family CLI Configuration Guide
23-14
Capability parameters (type of interface, Gigabit Ethernet at both ends, or 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).
An interface enters the suspended state if the interface is configured in the ON mode.
An interface enters the isolated state if the interface is configured in the ACTIVE mode.
