VPLS Service Commands
7750 SR OS Services Guide Page 833
Description This command controls the period of time that the Registrar state machine will wait in the leave state
before transitioning to the MT state when it is removed. An instance of the timer is required for each
state machine that is in the leave state. The Leave Period Timer is set to the value leave-time when it
is started.
A registration is normally in “in” state where there is an MFIB entry and traffic is being forwarded.
When a “leave all” is performed (periodically around every 10-15 seconds per SAP/SDP binding -
see leave-all-time-below), a node sends a message to its peer indicating a leave all is occurring and
puts all of its registrations in leave state.
The peer refreshes its registrations based on the leave all PDU it receives and sends a PDU back to the
originating node with the state of all its declarations.
Refer to IEEE 802.1ak-2007 section 10.7.4.2.

Description This command controls the frequency with which the LeaveAll state machine generates LeaveAll
PDUs. The timer is required on a per-Port, per-MRP Participant basis. The Leave All Period Timer is
set to a random value, T, in the range LeaveAllTime<T<1.5*leave-all-time when it is started. Refer to
IEEE 802.1ak-2007 section 10.7.4.3.
Default 100
Parameters value — [60-300] tenths of a second
periodic-time
Syntax [no] periodic-time value

Description This command controls the frequency the PeriodicTramsmission state machine generates periodic
events if the Periodic Transmission Timer is enabled. The timer is required on a per-Port basis. The
Periodic Transmissing Timer is set to one second when it is started.
Default 10
Parameters value — [10-100] tenths of a second
