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 10 — 650
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 1 — 100
sd-time — Specifies an integer to define the signal degrade hold-down time in milliseconds.
