Manually Collecting Topology Information; Enabling The Cluster Function - HP 5500 EI Series Configuration Manual

The delay settings are conveyed in topology requests sent to the requested switches. They help
avoid concurrent responses to an NTDP topology-collection request causing congestion and deny
of service on the management switch.
To configure NTDP parameters:
Step
1. Enter system view.
2. Configure the maximum hops for topology
collection.
3. Configure the interval for collecting topology
information.
4. Configure the delay for the first
NTDP-enabled port to forward a
topology-collection request.
5. Configure the delay for other NTDP-enabled
ports to forward a topology-collection
request.

Manually collecting topology information

The management switch collects topology information periodically after a cluster is created. In addition,
you can manually start topology information collection on the management switch or NTDP-enabled
switch, thus managing and monitoring switches in real time, regardless of whether a cluster is created.
To configure to manually collect topology information:
Task
