Parameter
members: Displays the information about the members of a stack. Do not specify this
keyword when you execute this command on a slave switch.
Description
Use the display stacking command to display the information about the main switch or
the slave switches of a stack.
When you execute this command on a main switch, the information displayed depends
on the members keyword as follows:
z If the members keyword is not specified, the output information indicates that the
local switch is the main switch. Besides, the number of the switches contained in
the stack is also displayed.
z If the members keyword is specified, the information about the members of the
stack is displayed, including the stack numbers of the main/slave switches, stack
name, stack device name, MAC address and status.
When you execute this command on a slave switch, the information displayed indicates
that the local switch is a slave switch. Besides, the information such as the stack
number of the local switch, and the MAC address of the main switch in the stack is also
displayed.

1.1.5 stacking ip-pool
Syntax
stacking ip-pool from-ip-address ip-address-number [ ip-mask ]
undo stacking ip-pool
View
System view
Parameter
from-ip-address: Start address of the stack IP address pool.
ip-address-number: Number of the IP addresses in the stack IP address pool. A stack
IP address pool contains 16 addresses by default.
ip-mask: Mask of the stack IP address.
Description
Use the stacking ip-pool command to create a stack IP address pool.
Use the undo stacking ip-pool command to restore the default stack IP address pool.
You need to create an IP address pool for a stack before creating the stack. When
adding a switch to a stack, the main switch picks an IP address from the IP address
pool and assigns the IP address to it.
The stacking ip-pool command can only be executed on switches that do not belong
to any stack. That is, the IP address pool of an existing stack cannot be modified.
To add a switch to a stack successfully, make sure the value of the ip-address-number
argument is larger than the number of switches currently contained in the stack.
Make sure the IP addresses in the IP address pool of a stack are successive so that
they can be assigned successively. For example, the IP addresses in an IP address
pool with its start IP address something like 223.255.255.254 are not successive. In this
case, errors may occur when adding a switch to the stack.
IP addresses in the IP address pool of a stack must be of the same network segment.
For example, the 1.1.255.254 is not a qualified start address for a stack IP address
pool.
Note the following when performing stack-related configurations on the main switch of a
stack:
Command Manual (For Soliton) – Stack-Cluster

z After a stack is created, the main switch automatically adds the switches
connected to its stack ports to the stack.
z A slave switch quits the stack automatically when it is disconnected from the stack.
z If the IP address of the management VLAN interface of the main switch (or a slave
switch) is not of the same network segment as that of the stack address pool, the
main switch (or the slave switch) automatically removes the existing IP address
and picks a new one from the stack address pool as its IP address.
z Since both stack and cluster use the management VLAN and only one VLAN
interface is available on the S3100 switch, stack and cluster must share the same
management VLAN if you want to configure stack within a cluster.

# Configure the IP address pool for the stack.

undo ndp timer aging
View
System view
Parameters
aging-in-seconds: Holdtime of the NDP information, ranging from 5 to 255 seconds.
Description
Use the ndp timer aging command to set the holdtime of the NDP information. This
command specifies how long an adjacent device should hold the NDP neighbor
information received from the local switch before discarding the information.
Use the undo timer aging command to restore the default holdtime of NDP
information.
By default, the holdtime of NDP information is 180 seconds.
You can specify how long the adjacent devices should hold the NDP information
received from the local switch. When an adjacent device receives an NDP packet from
the local switch, it learns how long it should keep the NDP information of the switch
according to the holdtime carried in the NDP packet, and discards the NDP information
when the holdtime expires.
Note that NDP information holdtime should be longer than the interval between sending
NDP packets. Otherwise, a neighbor entry will be generated and age out frequently,
resulting in instability of the NDP port neighbor table.

Parameters
timer-in-seconds: Interval between sending NDP packets, ranging from 5 to 254
seconds.
Description
Use the ndp timer hello command to set the interval between sending NDP packets.
Use the undo ndp timer hello command to restore the default interval.
By default, this interval is 60 seconds.
A switch should update the NDP information of its neighbors regularly, so that the
switch can get the updated information of the neighbors in time. You can use the ndp
timer hello command to specify the interval at which the switch sends hello packets to
its neighbors for NDP information update.
Note that NDP information holdtime should be longer than the interval between sending
NDP packets. Otherwise, a neighbor entry will be generated and age out frequently,
resulting in instability of the NDP port neighbor table.
Examples
# Set the interval between sending NDP packets to 80 seconds.

2.2.4 ntdp explore
Syntax
ntdp explore
View
User view
Parameters
None
Description
Use the ntdp explore command to manually start a topology collection process.
NTDP is able to periodically collect topology information. In addition, you can use this
command to manually start a topology collection process at any moment. If you do this,
NTDP collects NDP information from all devices in a specific network range (which can
be set through the ntdp hop command) as well as the connection information of all its
neighbors. Through this information, the management device or the network
management software knows the topology in the network range, and thus it can
manage and monitor the devices in the range.
Examples
# Start a topology collection process.
<Sysname> ntdp explore

Commands
2-12
Parameters
hop-value: Maximum hops to collect topology information, namely, the topology
collection range, in the range of 1 to 16.
Description
Use the ntdp hop command to set the topology collection range.
Use the undo ntdp hop command to restore the default topology collection range.
By default, the topology collection range is three hops.
With the ntdp hop command, you can specify to collect topology information from the
devices within a specified range to avoid infinite collection. That is, you can limit the
range of topology collection by setting the maximum hops from the collecting device to
the collected devices. For example, if you set the maximum hops to two, the switch
initiating the topology collection collects topology information from the switches within
two hops.
Note that:
z The topology collection range set by this command is applicable to both the
periodic and manual topology collection.
z This command is only applicable to topology-collecting device, and a wider
collection range requires more memory of the topology-collecting device.
Examples
# Set the topology collection range to 5 hops.
<aaa_0.Sysname> system-view
System View: return to User View with Ctrl+Z.
[aaa_0.Sysname] ntdp hop 5
2.2.6 ntdp timer
Syntax
ntdp timer interval-in-minutes
undo ntdp timer
View
System view
Parameters
interval-in-minutes: Interval (in minutes) to collect topology information, ranging from 0
to 65,535. A value of 0 disables topology information collection.
