Automatically Removing a Circuit
Using the automatic circuit removal feature, which comes enabled, network DLCIs
and PVCs can be automatically removed from the unit’s configuration when the
network service provider no longer supports them. Automatic deletion is based
upon information from a LMI full status response on an active frame relay link.
When this feature is set to:
n Enable – The following will be automatically removed from the unit’s
configuration:
— Unsupported network DLCIs and PVC connections that include
multiplexed network DLCIs.
— Standard network DLCIs that are Payload Managed or IP Enabled.
— Unsupported standard network DLCIs that are not configured as the
primary destination in a management PVC.
— Non-management PVCs in which unsupported standard network DLCIs
are included.
— DLCIs not included in three consecutive LMI full status response
messages.
— LMI status responses that indicate a Deleted status for the DLCI.
All configured options relating to the deleted circuits are also deleted and they
revert to their default settings.
A DLCI will not be deleted if the physical interface or frame relay link is down,
or if the DLCI is used for the TS Management Link.
n Disable – Unused network DLCIs, PVC connections, and management PVCs
must be manually removed.
If the model has ISDN backup capability, ISDN Link Profiles associated with
the deleted records and alternate destinations will be deleted, as well.
