Xstp High Availability - Nokia 7302 Manual

FD 100/320Gbps NT and FX NT IHub Services Guide
The T-LDP control plane behavior will be the same as the control word for VLL
services. This means that an ISAM PE will not be able to negotiate with the peer PE
whether the control word should be used. The C bit in the pseudowire FEC sent in
the label mapping message is set to a value of 1 when the control word is enabled.
The configuration for the two directions of the Ethernet pseudowire should match.
Each node will signal the C bit value as per the local mesh-sdp or spoke-sdp
configuration. A SR-Series node receiving a label mapping message with a C bit
different from the local configuration must withdraw its own label mapping message
if one was sent. The service will only come up if the same C bit value is signaled in
both directions.

High Availability Enhancement for Duplex NT is introduced for xSTP Protocols
(RSTP/MSTP) from Release 4.3.01.
When a switchover to the stand-by NT board occurs due to failure of the active NT
or a forced NT switchover from management, all the xSTP port states and port roles
remain intact and are not re-calculated again on the newly active NT. This prevents
any topology change in an already converged network during NT switchover.

5.4.8.1
A service ingress access QoS policy defines the match criteria used to determine the
Flow Class for each packet, entering via an SAP. The operator can configure ingress
access QoS policy for the service. By default each v-VPLS/VPLS service is
associated the default ingress access QoS policy: policy ID 1.
5.4.8.2
A service egress network QoS policy defines the match criteria used to determine the
mapping of Flow Class and profile indication to EXP bits. Marking of the EXP bits in
both labels (transport and VC) of the PW is performed. The operator can configure
egress network QoS policy for the service. By default each VPLS service is
associated the default egress network QoS policy: policy ID 1.
