Table 49: show aps Output Fields

Field Name

Field Description

Level of Output

Interface

Name of the SONET/SDH interface.

All levels

Group

Group name.

All levels

Circuit

Circuit type: Working or Protect.

All levels

Intf State

State of the circuit and interface in the format circuit-state, interface-state:

For circuit-state:

enabled

disabled

invalid

unknown

For interface-state:

degraded

down

invalid

nonexistent

unknown

up

All levels

Neighbor

Address and state of neighbor interface. If the working and protect interfaces are on the same router, the neighbor address is displayed as 0.0.0.0.

detail extensive

adj

State of the neighbor adjacency:

Down

Init

Invalid

Unknown

Up

detail extensive

neighbor interface

State of the neighbor interface: enabled or disabled.

detail extensive

dead

Number of seconds before the neighbor is declared dead

detail extensive

Channel state

Circuit that has been selected: Working or Protect.

detail extensive

Local-mode

Mode in which the local router is configured to interoperate with SONET line-terminating equipment (LTE): unidirectional or bidirectional. The parenthetical value represents the mode type in the K2 byte.

extensive

neighbor-mode

Mode in which the neighboring device is operating: unidirectional or bidirectional. The parenthetical value represents the mode type in the K2 byte.

extensive

Protect circuit is on

Interface name of the APS protect circuit, displayed when both the working circuit and protect circuit are on the same router.

detail extensive

Working circuit is on

Interface name of the APS working circuit, displayed when both the working circuit and protect circuit are on the same router.

detail extensive

Req K1

Value of the SONET/SDH K1 byte requested to be transmitted by this circuit.

extensive

rcv K1

Value of the SONET/SDH K1 byte received on this interface. (Valid only on the protect circuit.)

extensive

xmit K1

Value of the SONET/SDH K1 byte being transmitted on this interface. (Valid only on the protect circuit.)

extensive

nbr K1

Value of the SONET/SDH K1 byte requested to be transmitted by the neighbor.

extensive

nbr paired req

Nonzero if the neighbor is requesting a particular K1 value because of a change in the paired circuit.

extensive

Revert time

Configured time to wait after the working circuit has become functional before making the working circuit active again.

extensive

neighbor revert time

Configured time, on the neighbor interface, to wait after the working circuit has again become functional before making the working circuit active again.

extensive

Hello due in

Time until the next hello packet is sent.
