the exchange of an additional, Cisco-specific LACP type length value (TLV) that
contains the ordering information.
-
Not
operational—A consistent set of link ordering numbers (LONs) has not been
received by a higher priority partner, or the LONs to be made active are not

Switchover
type:
|
Method of
performing an mLACP switchover on the bundle with the following possible
values:
-
Brute
force— Trigger the failover by marking member(s) as Not Aggregatable instead of
using dynamic priority management. This is the only possible method of control
when the dual-homed device (DHD) is the higher-priority system. Only applies to
mLACP bundles.
-
Non-revertive—This is the default. Dynamic priority management
is used, where the bundle does not fail back to the originally active point of
attachment (PoA) except when a subsequent failure occurs.
-
Revertive—Dynamic priority management is used, but the
higher-priority device (based on the configured port priorities for the bundle)
is always Active unless it has encountered a failure. This means that if a
failure is encountered triggering a switchover, once the failure condition is
cleared the initially-active links become active again.
The
switchover type can be changed from the default behavior using the
mlacp switchover
type command,
|
Recovery
delay:
|
Number of
seconds (s) to delay becoming the active mLACP device after recovering from a
failure, using the
mlacp switchover recovery
delay command.
"None"
is displayed when the
mlacp switchover recovery
delay command is not configured.
|
Maximize
threshold:
|
Threshold
value below which mLACP switchovers are triggered to allow the bundle to reach
the configured maximum number of active links or bandwidth (using the
mlacp switchover
maximize command), with the following possible values:
-
x links—Number of
active links used as the maximum threshold target to be maintained as a trigger
for an mLACP switchover on a bundle.
-
y kbps—Bandwidth in
kilobits per second used as the target threshold to be maintained as a trigger
for an mLACP switchover on a bundle.
-
Not
configured—The
mlacp switchover
maximize command is not configured. mLACP switchovers are based on
the minimum active links or bandwidth for the bundle.
|
IPv4 BFD:
|
Displays
whether or not IPv4-based bidirectional forwarding (BFD) is operating on the
bundle interface, with the following possible values:
-
Operational—All required configuration has been committed for
IPv4 BFD, and it is in use on the bundle.
-
Not
operational—IPv4 BFD is not working because some mandatory configuration is
missing on the bundle or on the active members of the bundle.
-
Not
configured—None of the mandatory configuration for IPv4 BFD has been committed
on the bundle, and the BFD sub-fields are not displayed.
|
State:
|
When BFD is
enabled, displays the state of BFD sessions on the bundle from the sessions
running on bundle members that is communicated to interested protocols, with
the following possible values:
-
Down—The
configured minimim threshold for active links or bandwidth for BFD bundle
members is not available so BFD sessions are down.
-
Off—BFD
is not configured on bundle members.
-
Up—BFD
sessions on bundle members are up because the minimum threshold for the number
of active links or bandwidth is met.

|
Displays
status of the BFD start timer that is configured using the
bfd address-family ipv4
timers start command, with the following possible values:
-
x s—Number of
seconds (from 60 to 3600) after startup of a BFD member link session to wait
for the expected notification from the BFD peer to be received, so that the
session can be declared up. If the SCN is not received after that period of
time, the BFD session is declared down.
-
Off—The
start timer is not configured, and a BFD session is only declared Down upon
notification from the BFD server.
|
Neighbor-unconfigured timer:
|
Displays
status of the BFD start timer that is configured using the
bfd address-family ipv4
timers nbr-unconfig command, with the following possible values:
-
x s—Number of
seconds (from 60 to 3600) to wait after receipt of notification that the BFD
configuration has been removed by a BFD neighbor, so that any configuration
inconsistency between the BFD peers can be fixed. If the BFD configuration
issue is not resolved before the specified timer is reached, the BFD session is
declared down.
-
Off—The
neighbor-unconfigured timer is not configured, and a BFD session is only
declared Down upon notification from the BFD server.

specifies the maximum number of echo packets that can be missed before a BFD
session is declared Down.
|
Destination
address:
|
Destination
IP address for BFD sessions on bundle member links that is configured using the
bfd address-family ipv4
destination command.
"Not
configured" is displayed when no destination IP address is configured.

-
Active—Link can send and receive traffic.
-
BFD
Running—Link is inactive because BFD is down or has not been fully negotiated.

transition to Active state without further exchange of LACP protocol data units
(PDUs).
