Operation Manual – Cluster Management
H3C S5500-EI Series Ethernet Switches
Caution:
You can only specify a management VLAN before establishing a cluster. After a
device has been added to the cluster, you cannot modify the management VLAN.
To change the management VLAN after the cluster is established, you should
remove the cluster on the management device, re-specify the management VLAN
and reestablish a cluster.
For the purpose of security, you are not recommended to configure the VLAN ID of
the management VLAN as the default VLAN ID of the port connecting the
management device to its member devices.
Only when the default VLAN ID of all subtending ports and the port connecting the
management device to its member device is that of the management VLAN, can the
packets without a tag from the management VLAN pass the ports. Otherwise, you
must configure the packets from the management VLAN to pass these ports. For
the configuration procedure, refer to VLAN Configuration in the Access Volume.
You must configure the IP address pool before establishing a cluster and configure
it on the management device only. If a cluster has already been established, you are
not allowed to change the IP address pool.
I. Manually establishing a cluster
Follow these steps to manually establish a cluster:
Enter system view
Specify the
management VLAN
Enter cluster view
Configure the private
IP address range for
member devices on a
device which is to be
configured as the
management device
To do... Use the command...
system-view
management-vlan vlan-id
cluster
ip-pool
administrator-ip-address
{ mask | mask-length }

Remarks
—
Optional
By default, VLAN 1 is the
management VLAN.
—
Required
For a cluster to work
normally, the IP addresses
of the VLAN interfaces of the
management device and
member devices must not be
in the same network
segment as that of the
cluster address pool.
