Services Overview
SDP (global) — when an SDP is shut down at the global service level, all bindings to that SDP are
put into the out-of-service state and the SDP itself is put into the administratively and operationally
down states. Packets that would normally be transmitted using this SDP binding will be discarded and
counted as dropped packets.
SDP (service level) — shutting down an SDP within a service only affects traffic on that service
from entering or being received from the SDP. The SDP itself may still be operationally up for other
services.
SDP Keepalives — enables SDP connectivity monitoring keepalive messages for the SDP ID.
Default state is disabled (shutdown), in which case the operational state of the SDP-ID is not affected
by the keepalive message state.
