PortChannel Configuration Chapter 23 Configuring PortChannels Send documentation comments to [email protected] Table 23-1 Channel Group Configuration Differences (continued) ON Mode ACTIVE Mode When you add or modify a PortChannel member port configuration, you must explicitly disable (shut) and enable (no shut) the PortChannel member ports at either end. When you add or modify a PortChannel interface, the PortChannel automatically recovers. Port initialization is not synchronized. There is synchronized startup of all ports in a channel across peer switches. All misconfigurations are not detected as no protocol is exchanged. Consistently detect misconfigurations using a PortChannel protocol. Transitions misconfigured ports to the suspended state. You must explicitly disable (shut) and enable (no shut) the member ports at either end. Transitions misconfigured ports to the isolated state to correct the misconfiguration. Once you correct the misconfiguration, the protocol ensures automatic recovery. This is the default mode. You must explicitly configure this mode. To configure active mode using Fabric Manager, follow these steps: Step 1 Step 2 Step 3 Expand ISLs and then select Port Channels in the Physical Attributes pane. You see the PortChannels configured in the Information pane. Click the Protocols tab and, from the Mode drop-down menu, select the appropriate mode for the Port Channel. Click the Apply Changes icon to save any modifications. About PortChannel Deletion When you delete the PortChannel, the corresponding channel membership is also deleted. All interfaces in the deleted PortChannel convert to individual physical links. After the PortChannel is removed, 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 (see the "Graceful Shutdown" section on page 20-11). If you delete the PortChannel for one port, then the individual ports within the deleted PortChannel retain the compatibility parameter settings (speed, mode, port VSAN, allowed VSAN, and port security). You can explicitly change those settings as required. • If you use the default ON mode to avoid inconsistent states across switches and to maintain consistency across switches, then the ports shut down. You must explicitly enable those ports again. • If you use the ACTIVE mode, then the PortChannel ports automatically recover from the deletion.
