Displaying LACP information for a specified LAG name or LAG ID
5
Defaulted (Def) Defaulted partner information is the set of LACP partner information (the
system priority, key, port priority, and state of the partner) that is used when
the information is not obtained from the partner through LACPDUs. This
occurs when LACPDUs are not properly received on time. When “Def” is
displayed, the actor’s receive state machine is using the defaulted partner
information that is configured administratively. If “No” is displayed, the actor’s
receive state machine is using the partner operational parameters that is
received in a LACPDU.
Expired (Exp) Indicates the state of the actor receive machine. If the LACP receive machine
does not receive any LACPDUs within the timeout period configured on a port,
the LACP receive machine goes into an EXPIRED state. The EXPIRED state
indicates that the LAG has stopped operating. When the actor receive
machine starts receiving LACPDUs from the port at the other end of the link, it
will begin operating again. When “Exp” is displayed, the actor receive machine
is in the EXPIRED state. When “No” is displayed, the actor receive machine is
operating and is not in the EXPIRED state.
Operating (Ope) Indicates the operating status of the port. The port status can be one of the
following:
•
Ope (operating) - The port is operating normally.
•
Ina (inactive) - The port is inactive because the port on the other side of
the link is down or has stopped transmitting LACP packets.
•
Blo (blocked) - The port is blocked because the adjacent port of the LAG
is not configured with link aggregation. To unblock the port and bring it to
an operational state, enable link aggregation on the adjacent port and
ensure that the ports have the same key.
Port Number (Port Num) The port number of the LAG.
Actor System MAC The system MAC address of the actor. The system priority and system MAC
address together form the system identifier.
Partner System MAC The system MAC address of the partner. The system priority and system MAC
address together form the system identifier.
LACP RX Count The number of LACP packets received on a port.
LACP TX Count The number of LACP packets sent on a port.
LACP Err Count LACP is under the category of slow protocols. Slow protocol packets are
received with an illegal subtype and a reserved subtype. LACP uses subtype 1,
and the marker protocol uses subtype 2. Subtype values from 3 to 10 are
reserved for future use. Subtype values 0 and 11 through 255 are considered
illegal subtype values.
Marker RX Count The number of marker packets received on a port. When a link is no longer
aggregated with the port on the other end of the link, the marker protocol is
used to verify that the conversation between the actor and the partner was
successful on both ends. The actor and the partner exchange Marker PDUs
and Marker Response PDUs to confirm the process.
