Configuring the management switch

Enabling NDP globally and for specific ports
For NDP to work normally, you must enable NTDP both globally and on specific ports.
Follow these steps to enable NDP globally and for specific ports:
To do...
Enter system view
Enable NDP globally
Enable the
NDP feature for
the port(s)
NOTE:
HP recommends that you disable NDP on a port which connects with the devices that do not need to join
the cluster. This prevents the management switch from adding and collecting topology information from
devices which do not need to joint the cluster.
Configuring NDP parameters
A port enabled with NDP periodically sends NDP packets to its neighbors. If no NDP information from
the neighbor is received to rest the holdtime, the holdtime times out and the device removes the
corresponding entry from the NDP table.
Follow these steps to configure NDP parameters:
To do...
Enter system view
Configure the interval for sending
NDP packets
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.
Enabling NTDP globally and for specific ports
For NTDP to work normally, you must enable NTDP both globally and on specific ports.
