Chapter 23 Configuring PortChannels Interfaces in a PortChannel Send documentation comments to [email protected] Step 3 Step 4 Step 5 Step 6 Click Next. You see an editable list of associated ISLs and available ISLs for this PortChannel. Click each associated ISL and click the left arrow to remove all ISLs from the PortChannel. Check the Delete Port Channel If Empty check box to delete this PortChannel. Click Finish to save any modifications or click Cancel to discard any changes. Interfaces in a PortChannel You can add or remove a physical interface (or a range of interfaces) to an existing PortChannel. The compatible parameters on the configuration are mapped to the PortChannel. Adding an interface to a PortChannel increases the channel size and bandwidth of the PortChannel. Removing an interface from a PortChannel decreases the channel size and bandwidth of the PortChannel. This section describes interface configuration for a PortChannel and includes the following topics: • About Interface Addition to a PortChannel, page 23-17 • Adding an Interface to a PortChannel, page 23-18 • Forcing an Interface Addition, page 23-19 • About PortChannel Deletion, page 23-16 • Deleting an Interface from a PortChannel, page 23-20 About Interface Addition to a PortChannel You can add a physical interface (or a range of interfaces) to an existing PortChannel. The compatible parameters on the configuration are mapped to the PortChannel. Adding an interface to a PortChannel increases the channel size and bandwidth of the PortChannel. A port can be configured as a member of a static PortChannel only if the following configurations are the same in the port and the PortChannel: • Speed • Mode • Rate mode • Port VSAN • Trunking mode • Allowed VSAN list or VF-ID list 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 (see the "Generation 1 PortChannel Restrictions" section on page 23-7 and "Graceful Shutdown" section on page 20-11). 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. OL-17256-03, Cisco MDS NX-OS Release 4.x Cisco MDS 9000 Family Fabric Manager Configuration Guide 23-17
