Default Port Operation - HP Aruba JL253A Management And Configuration Manual

LACP port trunk
configuration

Default port operation

In the default configuration, LACP is disabled for all ports. If LACP is not configured as Active on at least one end
of a link, the port does not try to detect a trunk configuration and operates as a standard, untrunked port. The
following table lists the elements of per-port LACP operation. To display this data for a switch, execute the
following command in the CLI:
switch# show lacp
Chapter 5 Port Trunking
Operation
• The port on the other end of the trunk link is configured for a static LACP trunk.
• You want to configure non-default Spanning Tree or IGMP parameters on an
LACP trunk group.
• You want an LACP trunk group to operate in a VLAN other than the default
VLAN and GVRP is disabled. (See VLANs and dynamic LACP on page
148.)
• You want to use a monitor port on the switch to monitor an LACP trunk.
The trunk operates if the trunk group on the opposite device is running one of the
following trunking protocols:
• Active LACP
• Passive LACP
• Trunk
This option uses LACP for the port Type parameter and TrkX for the port Group
parameter, where X is an automatically assigned value in a range corresponding
to the maximum number of trunks the switch allows. (See Port trunk features
and operation for the maximum number of trunk groups allowed on the
switches.)
Displaying static LACP trunk data : To list the configuration and status for a
static LACP trunk, use the CLI show lacp command. To list a static LACP trunk
with its assigned ports, use the CLI show trunk command or display the menu
interface Port/Trunk Settings screen.Static LACP does not allow standby ports.
