Optimizing Port Usage Through Traffic Control and Port Trunking

Port Trunking

LACP Port Trunk Operation

Configuration

Static LACP

The trunk operates if the trunk group on the opposite device is running one of the following trunking

 

protocols:

 

Active LACP

 

Passive LACP

 

Trunk

 

FEC

 

This option uses Trk1 for the port Group parameter and LACP for the port Type parameter.

 

Displaying Static LACP Trunk Data: To list the configuration and status for a static LACP trunk, use the

 

CLI show lacp command. To list a static LACP trunk with its assigned ports, use the CLI show trunk

 

command or display the menu interface Port/Trunk Settings screen.

 

Static LACP does not allow standby ports.

 

 

 

 

Default Port Operation

 

In the default configuration, all ports are configured for passive LACP. How-

 

ever, if LACP is not configured, the port will not try to detect a trunk config-

 

uration and will operate as a standard, untrunked port. The following table

 

describes the elements of per-port LACP operation. To display this data for a

 

particular switch, execute the following command in the CLI:

 

HP2512> show lacp

 

Table 6-7. LACP Port Status Data

 

 

Status Name

Meaning

 

 

Port Numb

Shows the physical port number for each port configured for LACP operation (1, 2, 3 . . .). Unlisted port

 

numbers indicate that the missing ports are assigned to a static Trunk group, an FEC trunk group, or are

 

not configured for any trunking.

LACP Enabled

Active: The port automatically sends LACP protocol packets.

 

Passive: The port does not automatically send LACP protocol packets, and responds only if it receives

 

LACP protocol packets from the opposite device.

 

A link having either two active LACP ports or one active port and one passive port can perform dynamic

 

LACP trunking. A link having two passive LACP ports will not perform LACP trunking because both ports

 

are waiting for an LACP protocol packet from the opposite device.

 

Note: In the default switch configuration, all ports are configured for passive LACP operation.

Trunk Group

Trk1: This port has been manually configured into a static LACP trunk.

 

Trunk Group Same as Port Number: The port is configured for LACP, but is not a member of a port trunk.
