Chapter 28 Cluster Commands
Cluster Management function enables a network administrator to manage the scattered devices in
the network via a management device. After a commander switch is configured, management and
maintenance operations intended for the member devices in a cluster is implemented by the
commander device.
cluster ndp
Description
The cluster ndp command is used to configure NDP globally. To return to the
default configuration, please use no cluster ndp command. NDP (Neighbor
Discovery Protocol) is used to discover the information of the directly connected
neighbor devices to support cluster establishing. An NDP-enabled device sends
NDP packets regularly to neighbor devices as well as receives NDP packets
from neighbor devices. An NDP packet carries the aging time, which indicates
the period of the receiving devices to keep the NDP packet.
Syntax
cluster ndp
cluster ndp timer {[ hello hello-time] [aging aging-time ]}
no cluster ndp
no cluster ndp timer {[ hello hello-time ] [ aging aging-time ]}
Parameter
hello-time —— Hello Time, which is the interval to send NDP packets. Hello
Time ranges from 5 to 254 in seconds. By default, it is 60.
aging-time —— Aging Time, which is the period for the neighbor switch to keep
the NDP packets from this switch. Aging Time ranges from 5 to 255 in seconds.
By default, it is 180.
Command Mode
Global Configuration Mode
Example
Enable NDP function globally, and configure Aging Time as 120 seconds, Hello
Time as 50 seconds:
TL-SG3424(config)# cluster ndp
TL-SG3424(config)# cluster ndp timer hello 50 aging 120
