Scheduling subnetwork discovery
The management system allows searching for and scheduling subnetwork discovery
using the Scheduled Tasks function.
Auto-discovery of VCGs
The
Connection Auto Discovery command-line tool is used to auto discover virtual
concatenation groups (VCGs), along with their server connections, in the network. The
Connection Auto Discovery command-line tool allows the management system to
discover the connections used for Ethernet transport even if they are provisioned with a
tool other than Lucent OMS.
For more information about the
Connection Auto Discovery command-line tool, see the
Lucent OMS Administration Guide.
Auto-discovery of CMISE NEs
CMISE NEs may be automatically discovered when a CMISE NE is reported as a
neighbor of a TL1 NE in the TL1 response used by the management system for
subnetwork discovery. Through this TL1 response, the management system cannot
determine that the reported NE is a CMISE NE, therefore the management system
assumes that the NE has a TL1 interface and attempts to log into it by sending TL1
commands. Since the CMISE NE does not understand TL1 commands, the
management system never successfully logs into the CMISE NE and the NE remains
an unknown NE in the management system database for an indefinite period of time.
Use the following procedures to prevent the management system from auto-discovery
of CMISE NEs.
•
If CMISE NEs are connected to a TL1 NE with DCC connectivity and will be
managed by the management system, these CMISE NEs should be manually added
to the management system before running subnetwork discovery. This will ensure
that the management system does not attempt to add these CMISE NEs since the
management system will recognize the NE name as belonging to a managed
CMISE NE.
•
If these CMISE NEs will not be managed by the management system, turn off
DCC connectivity between any TL1 NEs neighbors of these CMISE NEs before
running subnetwork discovery. This ensures that the TL1 NEs managed by the
management system, do not report the CMISE NEs as neighbors in the TL1
response.
If the management system does auto-discover a CMISE NE, the CMISE NE will
appear as an unknown NE and will remain as an unknown NE indefinitely since the
management system will never be able to log into the CMISE to discover its NE type.
If this occurs, and the CMISE NE will be managed by the management system, delete
the unknown NE representing the CMISE NE and add it to the management system as
a managed CMISE NE. If the CMISE NE will not be managed by the management
system, modify the NE type from unknown to either non-managed NE or
unmanageable device so that the management system will not auto-discover the
CMISE NE at a later time.
