Enabling Ntdp Globally And For Specific Ports - H3C S5510 Series Operation Manual

Operation Manual – Cluster Management
H3C S3610&S5510 Series Ethernet Switches
Configure the interval to
send NDP packets
Caution:
The time for the receiving device to hold NDP packets cannot be shorter than the
interval to send NDP packets; otherwise, the NDP table may become instable.

1.3.3 Enabling NTDP Globally and for Specific Ports

Follow these steps to enable NTDP globally and for specific ports:
Enter system view
Enable NTDP globally
Enable NTDP for the port
Caution:
For NTDP to work normally, you must enable NTDP both globally and on the
specified port.
The NTDP function is mutually exclusive with the BPDU TUNNEL function under a
port and you cannot enable them at the same time. For the detailed description of
the BPDU TUNNEL function, refer to BPDU TUNNEL part of the manual.
If the subtending port or the port connecting the management device to a
member/candidate device is a port of a member in an aggregation group, you must
enable NDP on all member ports of the aggregation group at the same time.
Otherwise, NDP will work abnormally.
You are recommended to 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.
