Enabling Ntdp Globally And For Specific Ports; Configuring Ntdp Parameters - HP 5500 EI Series Configuration Manual

Step
1. Enter system view.
2. Configure the interval for sending
NDP packets.
3. Configure the period for the
receiving switch to keep the NDP
packets.

Enabling NTDP globally and for specific ports

For NTDP to work normally, you must enable NTDP both globally and on specific ports.
To enable NTDP globally and for specific ports:
Step
1. Enter system view.
2. Enable NTDP globally.
3. Enter Ethernet interface view
or Layer 2 aggregate
interface view.
4. Enable NTDP on the port.

Configuring NTDP parameters

NTDP parameter configuration includes the following:
Limiting the maximum number of hops (devices) from which topology data is collected.
•
Setting the topology data collection interval.
•
• Setting the following topology request forwarding delays for requested switches' NTDP-enabled
ports:
Forwarding delay for the first NTDP-enabled port—After receiving a topology request, the
requested switch forwards the request out of the first NTDP-enabled port when this forwarding
delay expires rather than immediately.
Forwarding delay for other NTDP-enabled ports—After the first NTDP-enabled port forwards
the request, all other NTDP-enabled ports forward the request in turn at this delay interval.
