Parameter
interface
port-list: Specifies a port list. The list can
contain consecutive or separated ports, or the combination of the both. You
need to provide the port-list argument in the form of interface-type
interface-number [ to interface-type interface-number ]
&<1-10>, where interface-type specifies the port type, and interface-number
specifies the port number (in the form of unit ID/slot number/port number). to

Description
In system view:
Use the ndp enable command to enable
NDP globally.
Use the undo ndp enable command to
disable NDP globally.
When you execute the ndp enable
command in system view without the interface keyword, NDP is enabled
globally; when you do this with the interface keyword, NDP is enabled on
specified ports.
In Ethernet port view:
Use the ndp enable command to enable
NDP on the current port.
Use the undo ndp enable command to
disable NDP on the port.
When using this command in Ethernet port
view, you are not allowed to input the interface keyword and NDP is
enabled on the current port only.
By default, NDP is enabled both globally and
on ports.
Note that, unless NDP is enabled globally,
it does not take effect on a port even when it is enabled on the port.

Parameter
aging-in-seconds: Holdtime of the NDP information sent by this device, ranging from
5 to 255 seconds.
Description
Use the ndp timer aging command to set
the holdtime of the NDP information sent by this switch. This command specifies
how long receiving devices should hold the NDP neighbor information received
from this device 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 this device. When an
adjacent device receives a NDP packet from this device, it learns how long it
should keep the NDP information of this device 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 to send NDP packets. Otherwise, NDP port neighbor
table will become unstable.

Parameter
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 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.
Example
# Start a topology collection process.

Parameter
hop-value: Maximum
hops to collect topology information, ranging from 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 this command is only applicable
to topology-collecting device, and a wider collection range requires more
memory of the topology-collecting device.
Example
# Set the topology collection range to 5

Parameter
interval-in-minutes: Interval (in minutes) to collect topology information, ranging
from 0 to 65,535. Value 0 of this argument specifies not to perform periodic
topology collection.
Description
Use the ntdp timer command to configure
the interval to collect topology information periodically.
Use the undo ntdp timer command to
restore the default interval.
By default, this interval is one minute.
After the interval is set to a non-zero
value, the switch will collect topology information periodically at this
interval.
Note that:
l
If the display ntdp command displays
"disable" in the Timer field, it means this device is not a management
device and will not perform periodic topology collection.
l
After a cluster is set up on an S3600 series
switch, the switch will collect the topology information of the network at the
topology collection interval you set and automatically add the candidate
devices it discovers into the cluster.
l
If you do not want the candidate switches to be
automatically added into the cluster, you can set the topology collection interval
to zero.

Parameter
time: Device
forward delay in milliseconds. This argument ranges from 1 to 1,000.
Description
Use the ntdp timer hop-delay command
to set the delay for collected devices to forward topology collection requests
through their first port.
Use the undo ntdp timer hop-delay
command to restore the default device forward delay.
By default, the device forward delay is 200
ms.
Network congestion may occur if large
amount of topology response packets reach the collecting device in a short period.
To avoid this case, each collected switch in the network delays for a period
before it forwards a received topology collection request through the first forwarding
port. You can use the ntdp timer hop-delay command to set the delay.
You can use the command on a collecting switch.
The delay value you set by the ntdp timer hop-delay command is carried
in the topology collection requests sent by the collecting switch, and is used
by collected devices to determine how long they should wait before they can forward
the received topology collection requests through their first port.
Example
# Set the delay for collected switches to forward topology collection
requests through their first port to 300 ms.

Description
Use the ntdp timer port-delay
command to set the delay for collected switches to forward topology collection
requests through the next port.
Use the undo ntdp timer port-delay
command to restore the default port forward delay.
By default, the port forward delay is 20
ms.
Network congestion may occur if large
amount of topology response packets reach the collecting device in a short
period. To avoid this case, after a collected switch forwards a received
topology collection request through a port, it delays for a period before it
forwards the request through the next port. You can use the ntdp timer
port-delay command to set the delay.
You can use the command on a collecting
switch. The delay value you set by the ntdp timer port-delay command is
carried in the topology collection requests sent by the collecting switch, and
is used by collected devices to determine how long they should wait before they
forward the received topology collection requests through the next port.

Parameter
member-number: Member number assigned to the candidate device to be added to the
cluster. This argument ranges from 1 to 255.
H-H-H: MAC
address of the candidate device to be added (in hexadecimal).
password: Password
of the candidate device, a string of 1 to 256 characters. Password
authentication is required when you add a candidate device to a cluster unless the
candidate device is not configured with a password (in this case, you need not
input this argument).
Description
Use the add-member command to add a
candidate device to the cluster.
You can only use this command on the management
device of a cluster.
If you do not specify the member number when
adding a new cluster member, the management device assigns the next available member
number to the new member.
After you add a candidate device to the cluster,
the password of the device automatically changes to the management device password.
Note that, after a cluster is set up on an
S3600 series switch, the switch will collect the topology information of the
network at the topology collection interval you set and automatically add the
candidate devices it discovers into the cluster. If you do not want the
candidate switches to be automatically added into the cluster, you can set the
topology collection interval to zero (by the ntdp timer command), which
specifies not to perform periodic topology collection.
Example
# Add a candidate device to the cluster, setting the member number to 6.

Description
Use the administrator-address command
to add a device to a cluster by setting the management device MAC address and
cluster name of a cluster on the device.
Use the undo administrator-address
command to remove a member device from the cluster.
The commands here are generally used for
debugging and restore purpose.
By default, a switch does not belong to any
cluster.
A cluster has one and only one management
device. After you set the MAC address of the management device on a member
device, the member device is still able to identify the management device after
system reboot.
It is recommended to use the delete-member

Parameter
recover: Recovers

Description
Use the auto-build command to start
an automatic cluster building process.
You can execute this command on a candidate
device as well as on a management device.
When you execute this command on a
candidate device, you are prompted to enter a cluster name to build a cluster. Then,
the system automatically collects candidate devices and adds them to the
cluster.
When you execute this command on a management
device, the system directly collects candidate devices ant automatically adds
them to the cluster.
The recover keyword is used to
recover a cluster. After you execute the auto-build recover command, the
system looks for the down members in the member list and add them to the
cluster again.
Note that, the collection of
candidate/member devices are based on NTDP. So you must first enable NTDP. In
addition, you can use the ntdp hop command in system view to change
the collection range.
When the system automatically adds a device
to the cluster, if the user password configured for the device is different
from that of the management device, the device will not be successfully added
to the cluster.
l
After a cluster is built automatically, ACL 3998
and ACL 3999 will be generated automatically.

Description
Use the build command to build a
cluster with a cluster name or change the cluster name.
Use the undo build command to remove
the cluster.
You can use this command on a candidate
device as well as on a management device.
Executing the build command on a
candidate device will change the device to a management device and assign a name
to the cluster created on the device.
Executing the build command on a
management device will change the cluster name of the management device.
The member number of a management device is
0.
Note that, after a cluster is set up on an
S3600 series switch, the switch will collect the topology information of the
network at the topology collection interval you set and automatically add the
candidate devices it discovers into the cluster. If you do not want the
candidate switches to be automatically added into the cluster, you can set the
topology collection interval to zero (by the ntdp timer command), which
specifies not to perform periodic topology collection.
To reduce the risk of being attacked by malicious users against
opened socket and enhance switch security, the S3600 series Ethernet switches
provide the following functions, so that a cluster socket is opened only when
it is needed:
l
Opening UDP port 40000 (used for cluster) only
when the cluster function is implemented,
l
Closing UDP port 40000 at the same time when the
cluster function is closed.
On the management device, the preceding functions are implemented as
follows:
l
When you create a cluster by using the build
or auto-build command, UDP port 40000 is opened at the same time.
l
When you remove a cluster by using the undo
build or undo cluster enable command, UDP port 40000 is closed at
the same time.
On member devices, the preceding functions are implemented as
follows:
l
When you execute the add-member command
on the management device to add a candidate device to a cluster, the candidate
device changes to a member device and its UDP port 40000 is opened at the same
time.
l
When you execute the auto-build command
on the management device to have the system automatically add candidate devices
to a cluster, the candidate devices change to member devices and their UDP port
40000 is opened at the same time.
l
When you execute the administrator-address
command on a device, the device's UDP port 40000 is opened at the same time.
l
When you execute the delete-member
command on the management device to remove a member device from a cluster, the
member device's UDP port 40000 is closed at the same time.
l
When you execute the undo build command
on the management device to remove a cluster, UDP port 40000 of all the member
devices in the cluster is closed at the same time.
l
When you execute the undo
administrator-address command on a member device, UDP port 40000 of the

None
Description
Use the cluster enable command to enable
the cluster function.
Use the undo cluster enable command
to disable the cluster function.
By default, the cluster function is enabled.
To create a cluster on a device with the build
command, you must first execute the cluster enable command.
You can use the two commands on any devices
that support the cluster function.
l
When you execute the undo cluster enable
command on a management device, the cluster and all its members are removed, the
device stops operating as a management device, and the cluster function is
disabled on the device.
l
When you execute the undo cluster enable
command on a member device, the device leaves the cluster, and the cluster
function is disabled on the device.
l
When you execute undo cluster enable
command on a device that does not belong to any cluster, the cluster function
is disabled on the device.

View

Parameter
member-number: Member number of a member device, ranging from 1 to 255.
mac-address H-H-H:
Specifies the MAC address of a member device.
administrator: Switches back from the member device to the management device.
Description
Use the cluster switch-to command to
switch between the management device and a member device for configuration and
management.
On the management device, you can switch to
the view of a member device to configure and manage the member device, and then
switch back to the management device.
Both switching directions (from the
management device to a member device, and from a member device to the
management device) will use Telnet connection. Switching is performed based on
the following rules:
l
Both switching directions will perform
authentication. In a switching process, the system will authenticate the
level-3 super password. If the super password on the device that requests the
switching is inconsistent with that on the requested device, the switching
fails. When a candidate device joins the cluster, its super password will
automatically synchronize to the supper password on the management device. It
is recommended not to change the super password of any cluster member or the
management device, so as to avoid switching failure resulting from
authentication failure.
l
After you switch from the management device to a
member device, the member device view will inherit the user privilege level of
the current management device view.
l
After you switch from a member device to the
management device, the privilege level on the management device view will be determined
by the configuration on the management device.
l
If all the Telnet resources on the requested
device are used up, the switching to the device will not succeed.
When you execute this command on the management
device with an inexistent member number or a MAC address that is not in the
member list, an error will occur. In this case, you can enter quit to end
the switching.
Example
# Switch from the management device to number-6 member device and then
switch back to the management device.
<aaa_0.H3C> cluster switch-to 6
<aaa_6.H3C> quit
<aaa_0.H3C>

Parameter
H-H-H:
Multicast MAC address to be set for the cluster, in hexadecimal format. This
argument can be one of the following addresses: 0180-C200-0000, 0180-C200-000A,
0180-C200-0020 to 0180-C200-002F.
Description
Use the cluster-mac command
to configure a multicast MAC address for the cluster.
Use the undo cluster-mac command to
restore the default multicast MAC address.
The default multicast MAC address is
0180-C200-000A.
Note that, you can only use this command on
a management device.
The management device in a cluster is able
to periodically broadcast HGMP V2 multicast MAC synchronization packets. After you
configure a multicast MAC address on the management device, all the member/candidate
devices of the cluster will synchronize to the same multicast MAC address by
receiving multicast MAC synchronization packets. This guarantees that the
member/candidate devices of the cluster can receive the multicast packets from
the management device.
Example
# Configure multicast MAC address
0180-C200-0028 for the cluster.
<aaa_0.H3C> system-view
System View: return to User View with
Ctrl+Z.

Parameter
time-interval: Interval to send HGMP V2 multicast MAC synchronization packets, ranging
from 0 to 30 minutes.
Description
Use the cluster-mac syn-interval
command to set the interval for the management device to send HGMP V2 multicast
MAC synchronization packets periodically. You can only use this command on a
management device.
By default, this interval is one minute.
If you set this interval to zero on a
management device, the management device will not send HGMP V2 multicast MAC
synchronization packets to other devices.
Example
# Set the interval for the management
device to send HGMP V2 multicast MAC synchronization packets to one minute.

Parameter
member-number: Member number of a member device, ranging from 1 to 255.
Description
Use the delete-member command to
remove a member device from the cluster.
You can only perform the operation on a management
device. Otherwise, error will occur.
Note that, after a cluster is set up on an
S3600 series switch, the switch will collect the topology information of the
network at the topology collection interval you set and automatically add the
candidate devices it discovers into the cluster. If you do not want the
candidate switches to be automatically added into the cluster, you can set the
topology collection interval to zero (by the ntdp timer command), which
specifies not to perform periodic topology collection.

# Remove number-2 member device from the cluster.
