Optimizing Port Usage Through Traffic Control and Port Trunking

Port Trunking

 

Removing Ports from a Dynamic LACP Trunk Group. To remove a port

 

from dynamic LACP trunk operation, you must turn off LACP on the port. (On

 

a port in an operating, dynamic LACP trunk, you cannot change between LACP

 

dynamic and LACP passive without first removing LACP operation from the

 

port.)

 

 

C a u t i o n

Unless STP is running on your network, removing a port from a trunk can

 

result in a loop. To help prevent a broadcast storm when you remove a port

 

from a trunk where STP is not in use, HP recommends that you first disconnect

 

the link on that port.

 

Syntax: no interface <port-list>lacp

 

 

In this example, port 1 belongs to an operating, dynamic LACP trunk. To

 

remove port 1 from the dynamic trunk and return it to passive LACP, you would

 

do the following:

 

HP2512>(config)# no interface 1 lacp

 

HP2512>(config)# interface 1 lacp passive

 

Note that in the above example, if the port on the other end of the link is

 

configured for active LACP or static LACP, the trunked link will be re-

 

established almost immediately.

Web: Viewing Existing Port Trunk Groups

While the web browser interface does not enable you to configure a port trunk group, it does provide a view of an existing trunk group.

To view any port trunk groups:

Click on the Status tab.

Click on [Port Status].
