Usage
Information
This command provisions the port extender for automatic link aggregation group (LAG) port channel
creation on the connected ports. The LAG member ports must be operationally up and have a default port
configuration with no Layer 2 and Layer 3 configuration. The port interfaces must be of the same type.
You can configure up to 16 switch ports in the auto-LAG.
Use cascade interface interface slot/port-range peer in the Configuration Terminal
Batch Mode to provision the port extender in a dual-homing setup. It is recommended to configure the
port extender through batch mode only in a dual-homing setup. If the peer is not connected during the
configuration, ensure that you import the configuration from the peer once it is up. See import peer-
config on page 1364.
● The slot/port-range specifies a line card and either a single port number, a port range, or a
combination of both for auto-LAG configuration. The range of slot numbers is from 0 to 9 for linecard
slots. The range of port numbers is from 0 to 23.
