hold-time
Syntax

no hold-time
Context
config>port>aps
Description
This command specifies how much time can pass, in 100s of milliseconds, without receiving an advertise
packet from the neighbor before the multi-chassis signaling link is considered not operational.
The hold-time is usually 3 times the value of the advertise-interval. The value of the advertise-interval is
valid only for a multi-chassis APS as indicated by the value of neighbor IP address if it is not set to 0.0.0.0.
Parameters
hold-time — Specifies how long to wait for an APS advertisement packet before the peer in a Multi-Chassis
APS group is considered operationally down.
Values
hold-time-aps
Syntax
hold-time-aps [lsignal-failure sf-time] [lsignal-degrade sd-time]
no hold-time-aps
Context
config>port>aps
Description
This command configures hold-down timers to debounce signal failure conditions (lais, b2err-sf) and signal
degrade conditions (b2err-sd) for Uni 1+1 Sig+Data APS switching mode (switching mode uni-1plus1).
The no version of this command resets hol a specified string expression from an app-filter definition.
Default
0 (disabled)
Parameters
sf-time — Specifies an integer to define the signal failure hold-down time in milliseconds.
Values
sd-time — Specifies an integer to define the signal degrade hold-down time in milliseconds.
Values
neighbor
Syntax
neighbor ip-address
no neighbor
Context
config>port>aps
Description
This command specifies the neighbor's IP address only on a multi-chassis APS where the working and
protect circuits are configured on different routers. When the value the neighbor IP address is set to 0.0.0.0,
this implies that the APS group is configured as a single-chassis APS group.
