Interfaces in a PortChannel Chapter 23 Configuring PortChannels Send documentation comments to [email protected] 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: • 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). 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: • 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. See the "Reason Codes" section on page 20-8. Adding an Interface to a PortChannel To add an interface or range of interfaces to a PortChannel using Fabric Manager, follow these steps: Step 1 Expand ISLs and then select Port Channels in the Physical Attributes pane. You see the PortChannels configured in the Information pane (see Figure 23-14). 23-14 Cisco MDS 9000 Family CLI Configuration Guide OL-16184-01, Cisco MDS SAN-OS Release 3.x
