Port Trunking

Port Status and Configuration

 

Configuring a Static Trunk, Static FEC, or Static LACP Trunk Group.

 

For 2600, 2600-PWR, 4100gl, and 6108 switches:

 

Syntax:

trunk <port-list> < trk1 trk2 trk3 trk4 trk5 trk6 > < trunk fec lacp >

 

For 2800 switches:

 

Syntax:

trunk <port-list> < trk1 ... trk24 > < trunk fec lacp >

 

This example uses ports C4 - C6 to create a non-protocol static trunk group

 

with the group name of Trk2.

 

HPswitch(config)# trunk c4-c6 trk2 trunk

 

Removing Ports from a Static Trunk Group. This command removes

 

one or more ports from an existing Trkx trunk group.

Removing a port from a trunk can result in a loop and cause a broadcast storm.

 

When you remove a port from a trunk where STP is not in use, HP recommends

 

that you first disable the port or disconnect the link on that port.

 

Syntax:

no trunk < port-list >

 

 

This example removes ports C4 and C5 from an existing trunk group.

 

HPswitch(config)# no trunk c4-c5

Enabling a Dynamic LACP Trunk Group. In the default port configura­ tion, all ports on the switch are set to LACP Passive. However, to enable the switch to automatically form a trunk group that is dynamic on both ends of the link, the ports on one end of a set of links must be LACP Active. The ports on the other end can be either LACP Active or LACP Passive. This command enables the switch to automatically establish a dynamic LACP trunk group when the device ports on the other end of the link are configured for LACP Passive.
