22.2.3 Ethernet LOS criteria
Ethernet LOS Criteria feature adds the following condition types to the Core
protection switching criteria:
Note: The following are the default Core protection switching criteria:
•Core Card Missing
•Core Card Fail
Card Not Ready and Flash Card Realignment In Progress conditions represent inhibition of
the Core protection switching with respect to Operator Commands and the additional criteria
listed above.
22.2.4 Static LAG criteria
Static LAG Criteria feature is only available when the spare Core unit has been
installed.
By enabling Static LAG Criteria feature, the Ethernet ports of the Core unit in standby
are in the ON state (same as the ports of the Active Core unit), but the Ethernet traffic
is not forwarded. This behavior reduces the out of service time of user traffic passing
through the User Ethernet interfaces when Core protection switching occurs.
Static LAG Criteria must be provisioned "Disabled" when the NE is connected to
equipment performing Link Aggregation and not supporting the Active/Standby
management of aggregated links.
22.2.5 System priority parameter
The System Priority Parameter is the System Priority (2 bytes) associated to the NE.
This parameter, together with the System ID (the NE MAC address), determines the
System Aggregation Priority (8 bytes). The range for the System Priority parameter
is: 0 to 65,535 (default: 32,768).
