Re-initialize delay interval
In the default configuration, a port receiving
a disable
command followed immediately by a txonly
, rxonly
, or tx_rx
command delays re-initializing for two seconds, during which LLDP
operation remains disabled. If an active port is subjected to frequent
toggling between the LLDP disabled and enabled states, LLDP advertisements
are more frequently transmitted to the neighbor device. Also, the
neighbor table in the adjacent device changes more frequently as it
deletes, then replaces LLDP data for the affected port which, in turn,
generates SNMP traps (if trap receivers and SNMP notification are
configured.) All of this can unnecessarily increase network traffic.
Extending the re-initialization-delay interval delays the ability
of the port to re-initialize and generate LLDP traffic following an
LLDP disable/enable cycle.
