DLCI Priority
Possible Settings: Low, Medium, High
Default Setting: High
Specifies the relative priority for data received on the DLCI from an attached device (also
known as quality of service). All data on Port 1 is cut-through, as long as there is no
higher-priority data queued from another user port. The DLCI priority set for an interface
applies to data coming into that interface. For example, the priority set for DLCIs on Port 1
applies to data coming into Port 1 from the attached equipment (such as a router).
NOTE: For units with multiple user data ports, since pipelining occurs on Port-1, it is
recommended that higher priority data be connected to Port-1 .
Display Conditions – This option is not available for the network interface or, if the
model has ISDN backup capability, an ISDN DBM interface.
Low – Data configured for the DLCI has low priority.
Medium – Data configured for the DLCI has medium priority.
High – Data configured for the DLCI has high priority.
Outbound Management Priority
Possible Settings: Low, Medium, High
Default Setting: Medium
Specifies the relative priority for management traffic sent on management PVCs on this
DLCI to the network.
Display Conditions – This option is not available on a user data port or a virtual router
port.
Low – Management data configured for the DLCI has low priority.
Medium – Management data configured for the DLCI has medium priority.
High – Management data configured for the DLCI has high priority.
Backup Group
Possible Settings: A, B, C, . . . Z, None
Default Setting: None
Assigns DLCIs to a backup group so backup does not take place unless all DLCIs in the
group are no longer operational or latency has been exceeded. Backup is terminated
when one DLCI in the group is operational again. This feature reduces backup charges
when redundant PVCs have been configured.
Display Conditions – This option is not available on a user data port, a virtual router
port, or an ISDN DBM interface.
A – Z – Specifies the designation for this group of DLCIs. Only DLCIs in a PVC will be
considered part of a Backup Group.
None – No Backup Groups have been set up.
