Port Trunking

 

Port Status and Configuration

 

 

N o t e

Dynamic LACP trunks operate only in the default VLAN (unless GVRP is

 

enabled and Forbid is used to prevent the trunked ports from joining the default

 

VLAN). Thus, if an LACP dynamic trunk forms using ports that are not in the

 

default VLAN, the trunk will automatically move to the default VLAN unless

 

GVRP operation is configured to prevent this from occurring. In some cases,

 

this can create a traffic loop in your network. For more on this topic, refer to

 

“VLANs and Dynamic LACP” on page 12-24.

 

In most cases, trunks configured for LACP operate as described in table 12-4

 

 

on the next page.
