HP 445942-001 manual Link Aggregation Control Protocol configuration, Lacp Port configuration

Configuration Commands

Link Aggregation Control Protocol configuration

The following table describes the LACP Configuration commands.

Table 115 LACP Configuration commands

CommandDescription

lacp system-priority {<1-65535>}

lacp timeout {shortlong}

Defines the priority value (1 through 65535) for the switch. Lower numbers provide higher priority. The default value is 32768.

Command mode: Global configuration

Defines the timeout period before invalidating LACP data from a remote partner. Choose short (3 seconds) or long (90 seconds). The default value is long.

NOTE: HP recommends that you use a timeout value of long, to reduce LACPDU processing. If your switch’s CPU utilization rate remains at 100% for periods of 90 seconds or more, consider using static trunks instead of LACP.

LACP Port configuration

The following table describes the LACP Port Configuration commands. Table 116 LACP Port Configuration commands

CommandDescription

lacp mode {offactivepassive}

Set the LACP mode for this port, as follows:

•off—Turn LACP off for this port. You can use this port to manually configure a static trunk. The default value is off.

•active—Turn LACP on and set this port to active. Active ports initiate LACPDUs.

•passive—Turn LACP on and set this port to passive. Passive ports do not initiate LACPDUs, but respond to LACPDUs from active ports.

Command mode: Global configuration

lacp priority {<1-65535>}	Sets the priority value for the selected port. Lower numbers provide higher
	priority. Default is 128.
	Command mode: Global configuration
lacp key {<1-65535>}	Set the admin key for this port. Only ports with the same admin key and oper
	key (operational state generated internally) can form a LACP trunk group.
	Command mode: Global configuration
show interface port	Displays the current LACP configuration for this port.
