HP UX Auto Port Aggregation (APA) Software manual Invoking lanadmin from the Command Line

-t-x-tportPPA anyLinkAggregatePPA

Displays the current port priority for the port with the specified portPPA number. For LACP_AUTO, this shows the priority value for the port. For HOT_STANDBY, this shows which port is used for traffic and which for standby. This option is not applicable to PAgP (FEC_AUTO).

-v-x-vlinkAggregatePPA

Displays the status for a given link aggregate with the specified linkAggregatePPA number. For example:

Link Aggregate PPA #	: 901
Number of Ports	: 3
Ports PPA	: 2 1	3
Link Aggregation State	: LINKAGG AUTO
Group Capability	: 901
Load Balance Mode	: MAC Address based (LB_MAC)

-y-x-ylinkaggregatePPA

Displays the Hot Standby status for the link aggregate with the specified linkAggregatePPA number.

vmtu [-x vmtu linkaggregatePPA]

Displays the TSO status for a given link aggregate with the specified linkAggregatePPA number. For example:

#lanadmin -x vmtu 903

Driver/Hardware does not support TCP Segmentation Offload

#

#lanadmin -x vmtu 905

Driver/Hardware supports TCP Segmentation Offload, Current VMTU = 32160

#

The following option is supported, but with a different meaning:

-aDisplays the current station address of link aggregate with the specified linkAggregatePPA number.

Invoking lanadmin from the Command Line

NOTE: Remember that the starting PPA number for link aggregates varies with the operating

system you have installed: for HP-UX 11.00, it is 100; and for 11i v1 and 11i v2, it is 900. The following example uses HP-UX 11i.

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

lanadmin -X-HlinkAggregatePPA

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. In this case, key is used instead of group_capability.
