hello-time
Syntax hello-time seconds
no hello-time
Context config>service>sdp>keep-alive
Description Configures the time period between SDP keepalive messages on the SDP-ID for the SDP
connectivity monitoring messages.
The no form of this command reverts the hello-time seconds value to the default setting.
Default hello-time 10 — 10 seconds between keepalive messages
seconds — The time period in seconds between SDP keepalive messages, expressed as a decimal
integer.
Values 1 — 3600
hold-down-time
Syntax hold-down-time seconds
no hold-down-time
Context config>service>sdp>keep-alive
Description Configures the minimum time period the SDP will remain in the operationally down state in response
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.
Default hold-down-time 10 — The SDP is operationally down for 10 seconds after an SDP keepalive error.
Parameters seconds — The time in seconds, expressed as a decimal integer, the sdp-id will remain in the
operationally down state before it is eligible to enter the operationally up state. A value of 0
indicates that no hold-down-time will be enforced for sdp-id.
Values 0 — 3600
max-drop-count
Syntax max-drop-count count
no max-drop-count
