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:
l
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.
l
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.
Example
# Display the information about a stack on
the main switch.
<stack_0.H3C> display stacking

Parameter
number:
Number of the slave switch to switch to.
Description
Use the stacking command to switch
to a slave switch to configure it.
You can use this command to switch from
user view of the main switch to user view of a slave switch. To switch from a
slave switch back to the main switch, execute the quit command in user
view.
Remove the IP
address configured for the existing Layer 3 interface first if you want to
cancel the stack-related configuration, otherwise, IP address conflicts may
occur.
Example
# Switch from the main switch H3C to the slave
switch numbered 1 and then switch back to the main switch.
<stack_0.H3C> stacking 1
<stack_1.H3C>
<stack_1.H3C> quit

Description
Use the stacking enable command to
create a stack.
Use the undo stacking enable command
to remove a stack.
The stacking enable command triggers
a main switch to add the switches connected to its stack ports to the stack.
The undo stacking enable command can
only be executed on a main switch.
A slave switch quits the stack
automatically when it is disconnected from the stack.
Example
# Create a stack.

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:
l
After a stack is created, the main switch
automatically adds the switches connected to its stack ports to the stack.
l
A slave switch quits the stack automatically
when it is disconnected from the stack.
l
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.
l
Since both stack and cluster use the management
VLAN and only one VLAN interface is available on the S3100-SI switch, stack and
cluster must share the same management VLAN if you want to configure stack
within a cluster.
Example
# Configure the IP address pool for the
stack.

Parameter
aging-in-secs: Holdtime (in seconds) to be set of the NDP information sent by the
local switch. This argument ranges from 5 to 255.
The default holdtime is 180 seconds.
Description
Use the ndp timer aging command to
set the holdtime of the NDP information sent by the local switch, that is, to
specify how long a device will hold the NDP packets received from the local
device. After the aging timer expires, the device removes the received NDP
neighbor node information.
Use the undo timer aging command to
restore the default NDP information holdtime.
You can specify how long an adjacent device
will hold the NDP information sent by the local device. An adjacent device holds
the NDP information of the local switch according to the holdtime carried in the
NDP packets received from the local switch and removes the NDP information when
the aging timer expires.
Note that NDP information holdtime is
longer than the interval to send NDP packets. Otherwise, the neighbor
information table of an NDP port will become unstable.

Maximum hops for collecting topology information, ranging from 1 to 16. By
default, the value is 3.
Description
Use the ntdp hop command to set a
range (in terms of hop count) for topology information collection.
Use the undo ntdp hop command
to restore the default range for topology information collection.
With the ntdp hop command, you can specify
to collect the topology information of the devices within a specified range to
avoid infinitive collection. The limit is performed by controlling the permitted
hops from collection origination. For example, if you set the hop number limit to
2, only the switches less than 2 hops away from the switch starting the
topology collection are collected.
Note that this command is only applicable to
the topology-collecting device. A broader collection scope requires more memory
of the topology-collecting device.

# Set the hop count for topology
information collection to 5.

Parameter
Interval-in-minutes: Interval (in minutes) to collect topology information, ranging
from 0 to 65,535. This argument defaults to 0, which specifies not to collect
topology information.
Description
Use the ntdp timer command to
configure the interval to collect topology information.
Use the undo ntdp timer command to
restore the default interval.
B y default, the interval to collect
topology information is 1 minute.
A switch collects topology information once
in each period set by the ntdp timer command.
Note that the (disable) prompt in the timer
field of the display ntdp command means that the device is not the
member of the cluster and does not perform periodical topology collection.
Example
# Set the interval to collect topology information to 30 minutes.

Parameter
time: Delay
time (in milliseconds) for a switch to forward topology-collection request
packets. This argument ranges from 1 to 1,000 and defaults to 200.
Description
Use the ntdp timer hop-delay command
to set the delay time for a switch to forward topology-collection request
packets.
Use the undo ntdp timer hop-delay
command to restore the default delay time.
To avoid network congestion caused by large
amount of topology response packets received in short periods, a switch delays
for specific period before it forwards a received topology-collection request
packet through its first ports. You can use the ntdp timer hop-delay
command to set the delay time.
These two commands are intended for
switches that collect topology information. They actually set the hop-delay
value for topology-collection request packets sent by these switches. The hop-delay
value determines the delay time for a switch receiving topology-collection
request packets to forward them through its first port.
Example
# Set the delay time for the switch to forward topology-collection
request packets through the first port to 300 ms.

Parameter
time: Delay
time (in milliseconds) for a switch to forward a topology-collection request
packet through its successive ports. This argument ranges from 1 to 100 and
defaults to 20.
Description
Use the ntdp timer port-delay
command to set the delay time for a switch to forward a received
topology-collection request packet through its successive ports. A switch
forwards received topology request packets to all its ports in turn. After
forwarding a received topology-collection request packet through one port, the
switch delays for specific period before it forwards the packet through the
next port.
Use the undo ntdp timer port-delay
command to restore the default delay time.
To avoid network congestion caused by large
amount of topology response packets received in short periods, a switch delays
for specific period before it forwards a received topology-collection request
packet through the next port. You can use the ntdp timer port-delay

Parameter
member-number: Member number assigned to the candidate device to be added to a
cluster. This argument ranges from 1 to 255.
H-H-H: MAC
address of the candidate device (in hexadecimal).
password:
Password of the candidate device, a string comprising 1 to 256 characters. The
password is required when you add a candidate device to a cluster. However,
this argument is not needed if the candidate device is not configured with a
password.
Description
Use the add-member command to add a
candidate device to a cluster.
You can add a candidate device to a cluster
on the management device only.
If you do not specify the member number
when adding a cluster member, the management device assigns the least available
member number to it.
After a candidate device is added to a
cluster, its device password becomes the management device password.
Example
# Add a candidate device to the cluster, setting the member number to
6. (Assume that the MAC address and user password of the candidate device are 000f-e20f-35e7
and 123456.)
