Port Trunking
Trunk Group Operation Using LACP
The switch will not allow you to configure LACP on a port on which port
security is enabled. For example:
ProCurve(config)# int a17 lacp passive
Error configuring port A17: LACP and port security cannot
be run together.
ProCurve(config)#
To restore LACP to the port, you must remove port security and re-enable
LACP active or passive.
Changing Trunking Methods.
To convert a trunk from static to dynamic,
you must first eliminate the static trunk.
Static LACP Trunks.
Where a port is configured for LACP (Active or
Passive), but does not belong to an existing trunk group, you can add that port
to a static trunk. Doing so disables dynamic LACP on that port, which means
you must manually configure both ends of the trunk.
Dynamic LACP Trunks.
You can configure a port for LACP-active or LACP-
passive, but on a dynamic LACP trunk you cannot configure the other options
that you can on static trunks. If you want to manually configure a trunk, use
the
trunk command. (Refer to “Using the CLI To Configure a Static or Dynamic
VLANs and Dynamic LACP.
A dynamic LACP trunk operates only in the
default VLAN (unless you have enabled GVRP on the switch and use
Forbid to
prevent the ports from joining the default VLAN).
■
If you want to use LACP for a trunk on a non-default VLAN and GVRP is
disabled, configure the trunk as a static trunk.
