Global Service Command Reference
1. This condition should not occur.
hello-time
Syntax hello-time seconds
no hello-time
Context config>service>sdp>keep-alive
Description This command 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.
Parameters seconds — the time period in seconds between SDP keepalive messages, expressed as a decimal
hold-down-time
Syntax hold-down-time seconds
no hold-down-time
Context config>service>sdp>keep-alive
Description
This command 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.
