Configuring The Management Device; Enabling Ndp Globally And For Specific Ports; Configuring Ndp Parameters - HP 5820X Switch Configuration Manual

Configuring the management device

Enabling NDP globally and for specific ports

For NDP to work normally, you must enable NTDP both globally and on specific ports.
To enable NDP globally and for specific ports:
To do...
1. Enter system view.
2. Enable NDP globally.
3. Enable the
NDP
feature for
the ports.
NOTE:
HP recommends that you disable NDP on the port which connects with the devices that do not need to
join the cluster, preventing the management device from adding the device which needs not to join the
cluster and collecting the topology information of this device.

Configuring NDP parameters

A port enabled with NDP periodically sends NDP packets to its neighbors. If no NDP information from
the neighbor is received when the holdtime times out, the device removes the corresponding entry from
the NDP table.
To configure NDP parameters:
To do...
1. Enter system view.
2. Configure the interval for
sending NDP packets.
3. Configure the period for the
receiving device to keep the
NDP packets.
CAUTION:
The time for the receiving device to hold NDP packets cannot be shorter than the interval for sending
NDP packets; otherwise, the NDP table may become instable.
Use the command...
