DETAILED STEPS
Command or Action Purpose
Step 1
aps group number
Example:
RP/0/RSP0/CPU0:router(config)# aps group
1
Adds an APS group with a specified number and enters APS group
configuration mode.
• Use the aps group command in global configuration mode.
• To remove a group, use the no form of this command, as in: no
aps group number, where the value range is from 1 to 255.
Note To use the aps group command, you must be a member of
a user group associated with the proper task IDs for APS
commands.
Note The aps group command is used even when a single
protect group is configured.
Step 2
channel 0 local sonet interface
or
channel 0 remote ip-address
Example:
RP/0/RSP0/CPU0:router(config-aps)#
channel 0 local SONET 0/0/0/1
or
RP/0/RSP0/CPU0:router(config-aps)#
channel 0 remote 172.18.69.123
Creates a protect channel for the APS group, where 0 designates a
protect channel.
Note The protect channel must be assigned before the active
channel can be assigned.
Note To configure APS where both channels are on one router,
use the channel local command for both the protect and
active channels.
To configure APS using two different routers where the
active channel is on one router and the protect channel is on
another router, use the channel local command for either
the protect or the active channel, but use the channel
remote command for the other channel.
Step 3
channel 1 local sonet interface
or
channel 1 remote ip-address
Example:
RP/0/RSP0/CPU0:router(config-aps)#
channel 1 local SONET 0/0/0/2
or
RP/0/0/CPU0:router(config-aps)# channel 1
remote 172.18.69.123
Creates an active channel for the APS group, where 1 designates an
active channel.
Note The active channel must be assigned after the protect
channel is assigned.
Note To configure APS where both channels are on one router,
use the channel local command for both the protect and
active channels.
To configure APS using two different routers where the
active channel is on one router and the protect channel is on
another router, use the channel local command for either
the protect or the active channel, but use the channel
remote command for the other channel.
Step 4
signalling {sonet | sdh}
Example:
RP/0/RSP0/CPU0:router(config-aps)#
signalling sonet
Configures the K1K2 overhead byte used for automatic protection
switching (APS). The keyword options are:
• sonet—Sets signaling to SONET.
• sdh—Sets signaling to Synchronous Digital Hierarchy (SDH).
