HP UX Auto Port Aggregation (APA) Software manual Lloadbalancealgorithm linkAggregatePPA

-k-X-kportPPA admin_key anyLinkAggregatePPA

Sets the Administrative Key for an LACP_AUTO port or LACP_AUTO link aggregate. Applies to LACP_AUTO only. An Administrative Key and Operational Key are associated with each port. The Operational Key is used for forming aggregations in autonegotiation. The Administrative Key can be set at anytime. At the port level, the Operational Key only copies the Administrative Key value when the LACP protocol is not running. At the link aggregate level, the Operational Key only copies the Administrative Key when the link aggregate is not configured (no ports have joined the link aggregate).

For example: An LACP_AUTO port is in an aggregation. The admin_key and oper_key are 1234. Use lanadmin -X -k admin_key anyLinkAggregatePPA to modify the admin_key to 5432. The oper_key is not changed immediately. You must stop LACP_AUTO for the port and then restart it for both keys to have the new value of 5432.

-l-X-lload_balance_algorithm linkAggregatePPA

Sets the load-balancing algorithm for a link aggregate with the specified linkAggregatePPA number.

The following choices are valid for load_balance_algorithm:

•LB_MAC

•LB_IP

•LB_PORT

For a description of these parameters, see the load distribution algorithms in “Link Aggregate Advanced Parameters” (page 34).

-o-X-olinkAggregatePPA

Clears data flows for a link aggregate specified by linkAggregatePPA. This rebalances the link aggregate outbound traffic across the ports in the link aggregate.

-p-X-pportPPA config_mode anyLinkAggregatePPA

Sets mode for a port with the specified portPPA number. The following values are valid:

•LACP_AUTO

•FEC_AUTO

•MANUAL

•LAN_MONITOR

For a description of these parameters, see the mode descriptions in “Preparing for Configuration” (page 31).

-s-X-sportPPA system_priority anyLinkAggregatePPA

Sets the system priority for an LACP_AUTO port. The default value is 0. This has no affect on a MANUAL or FEC_AUTO port.

-t-X-tportPPA port_priority anyLinkAggregatePPA

Sets the port_priority for the port with the specified PPA Number. For LACP_AUTO, this sets the priority value for the port. The lanapplyconf command assigns port priority according to settings in lanconfig.ascii. You can change the priority of primary and standby ports, but the primary port must have a higher priority. By default a primary port is 5; standby is 3. This option is not applicable to PAgP. If the port is not in a standalone state, attempting to set the port priority will fail. Check the port status using the lanadmin -x-pcommand.

The valid values for port_priority are integral numbers starting at 0.

For HOT_STANDBY: The bigger the number, the higher the priority.

For LACP ports: The smaller the number, the higher the priority.
