Invoking lanadmin from the Command Line

To obtain additional information on options for the lanadmin command, enter the following command:

lanadmin -X -H linkAggregatePPA

Where linkAggregatePPA can be any valid link aggregate PPA value.

To form a link aggregate of ports automatically using the Cisco Fast EtherChannel protocol on that port, set the port configuration mode to FEC_AUTO. For example, if port 2 must be trunked automatically, enter the following command:

lanadmin -X -p 2 FEC_AUTO 900

900 is the PPA of the first link aggregate. When the protocol completes successfully, HP APA determines the link aggregate into which port 2 best fits and adds the port to an aggregate based on the group_capability of ports and link aggregate. Ports in the same link aggregate must be connected to the same host and in the same trunk.

To form a link aggregate of ports automatically using the LACP protocol, use LACP_AUTO in place of FEC_AUTO and key instead of group_capability in the previous example.

To manually configure ports with PPAs 6, 7, 8, and 9 into a link aggregate lan901, enter the following command:

lanadmin -X -a 6 7 8 9 901

	CAUTION: Be careful when using the -a suboption. This might lead to an invalid link aggregate. This command gives you full control over forming any link aggregate that you want. This example configures ports with PPAs 6, 7, 8, and 9 into a single link aggregate, even if they are connected to different switches, which is an invalid configuration, and could lead to problems.

Before you can remove a port from an automatically formed link aggregate, you must turn off Cisco's Fast EtherChannel or LACP protocol on that port. If a port with a PPA number of 2 belongs to link aggregate lan900 (PPA number of 900), enter one of the following two commands:

lanadmin -X -d 2 900

or

lanadmin -X -p 2 MANUAL 900

To deconfigure FEC_AUTO (or LACP_AUTO) mode link aggregate 903, which has ports with PPAs 6, 7, 8, and 9, enter the following commands in succession:

# lanadmin -X -p 6 MANUAL 903
# lanadmin -X -p 7 MANUAL 903
# lanadmin -X -p 8 MANUAL 903
# lanadmin -X -p 9 MANUAL 903

Alternatively, the following single command achieves the same result:

lanadmin -X -d 6 7 8 9 903

To fully deconfigure a link aggregate, enter the following command:

lanadmin -X -c 903

	IMPORTANT: Failure to fully deconfigure a link aggregate can result in some properties being retained in the link aggregate. Subsequently, when you add new ports onto the link aggregate, they might not aggregate properly.

To delete a single port (for example, 8) from link aggregate 901, enter the following command:

lanadmin -X -d 8 901

To delete ports 6 and 9, enter:

lanadmin -X -d 6 9 901

To deconfigure the link aggregate 901 completely, enter:

lanadmin -X -c 901

This deletes the remaining port, 7, from link aggregate 901 and clears all the properties from the link aggregate; it becomes clean.

	IMPORTANT: After you delete all the ports from link aggregate 901, (after using, for example, lanadmin -X -d 7 901), use the -c suboption. Otherwise, some properties are retained in link aggregate 901. Subsequently, when you add new ports to link aggregate 901, they inherit old properties of the link aggregate and might not aggregate properly.
