Description
to SDP keepalive monitoring.
This parameter can be used to prevent the SDP operational state from "flapping" by rapidly
transitioning between the operationally up and operationally down states based on keepalive
messages.
When an SDP keepalive response is received that indicates an error condition or the max-drop-count
keepalive messages receive no reply, the sdp-id will immediately be brought operationally down. If a
keepalive response is received that indicates the error has cleared, the sdp-id will be eligible to be put
into the operationally up state only after the hold-down-time interval has expired.
The no form of this command reverts the hold-down-time seconds value to the default setting.
hold-down-time 10 — The SDP is operationally down for 10 seconds after an SDP keepalive error.
Default
