| Interface Configuration
Trunk Configuration
– 138 –
◆ Ports are only allowed to join the same Link Aggregation Group (LAG) if (1) the
LACP port system priority matches, (2) the LACP port admin key matches, and
(3) the LAG admin key matches (if configured). However, if the LAG admin key is
set, then the port admin key must be set to the same value for a port to be
allowed to join that group.
Note:
If the LACP admin key is not set when a channel group is formed (i.e., it has a
null value of 0), the operational value of this key is set to the same value as the port
admin key used by the interfaces that joined the group (see the “show lacp
internal” command in the CLI Reference Guide).
Parameters
These parameters are displayed:
Configure Aggregator
◆ Admin Key – LACP administration key is used to identify a specific link
aggregation group (LAG) during local LACP setup on the switch.
(Range: 0-65535)
If the port channel admin key is not set when a channel group is formed (i.e., it
has the null value of 0), this key is set to the same value as the port admin key
(see Configure Aggregation Port - Actor/Partner) used by the interfaces that
joined the group. Note that when the LAG is no longer used, the port channel
admin key is reset to 0.
If the port channel admin key is set to a non-default value, the operational key
is based upon LACP PDUs received from the partner, and the channel admin
key is reset to the default value. The trunk identifier will also be changed by this
process.
◆ Timeout Mode – The timeout to wait for the next LACP data unit (LACPDU):
■
Long Timeout – Specifies a slow timeout of 90 seconds. (This is the default
setting.)
■
Short Timeout – Specifies a fast timeout of 3 seconds.
The timeout is set in the LACP timeout bit of the Actor State field in
transmitted LACPDUs. When the partner switch receives an LACPDU set
with a short timeout from the actor switch, the partner adjusts the transmit
LACPDU interval to 1 second. When it receives an LACPDU set with a long
timeout from the actor, it adjusts the transmit LACPDU interval to 30
seconds.
If the actor does not receive an LACPDU from its partner before the
configured timeout expires, the partner port information will be deleted
from the LACP group.
When a dynamic port-channel member leaves a port-channel, the default
timeout value will be restored on that port.
