Port Trunking
Port Status and Configuration
Caution 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, ProCurve recommends that you first
disable the port or disconnect the link on that port.
Syntax: no interface <port-list> lacp
In this example, port C6 belongs to an operating, dynamic LACP trunk. To
remove port C6 from the dynamic trunk and return it to passive LACP, you
would do the following:
ProCurve>(config)# no interface c6 lacp
ProCurve>(config)# interface c6 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.
Trunk Group Operation Using LACP
The switch can automatically configure a dynamic LACP trunk group or you
can manually configure a static LACP trunk group.
Note LACP requires full-duplex (FDx) links of the same media type (10/100Base-T,
100FX, etc.) and the same speed, and enforces speed and duplex conformance
across a trunk group.
