Enabling The Logging Of Neighbor State Changes - HP 5500 EI series Configuration Manual

Step
3. Configure a system ID to host
name mapping for a remote
IS.
Configuring dynamic system ID to host name mapping
Static system ID to host name mapping requires you to manually configure a mapping for each router in
the network. When a new router is added to the network or a mapping must be modified, you must
configure all routers manually.
When you use dynamic system ID to host name mapping, you only need to configure a host name for
each router in the network. Each router advertises the host name in a dynamic host name CLV to other
routers so all routers in the network can have all mappings.
To help check the origin of LSPs in the LSDB, you can configure a name for the DIS in a broadcast
network.
To configure dynamic system ID to host name mapping:
Step
1. Enter system view.
Enter IS-IS view.
2.
3. Specify a host name
for the IS and enable
dynamic system ID to
host name mapping.
4. Return to system view.
5. Enter interface view.
6. Configure a DIS name.

Enabling the logging of neighbor state changes

With this feature enabled, the router delivers logs about neighbor state changes to its information center.
The information center processes the logs according to user-defined output rules (whether to output logs
and where to output). For more information about the information center, see Network Management and
Monitoring Configuration Guide.
To enable the logging of neighbor state changes:
Step
1. Enter system view.
