as a result cluster handshake messages cannot be properly sent or received and
devices will repeatedly join or leave the cluster.
■ If the routing table of the administrative device is full upon establishment of a
cluster, all candidate devices will repeatedly join or leave the cluster.
■ If the routing table of the administrative device is full when a candidate device
of a cluster joins the cluster, this device will repeatedly join or leave the cluster.
Creating a cluster and configuring cluster parameters manually
n
For Switch 7750 Ethernet switches, VLAN1 serves as the cluster management
VLAN and the IP address of the Layer-3 virtual interface of the management VLAN
must be configured before a cluster is created. After the cluster is created, it is
prohibited to change the interface IP address of the management VLAN.
Table 570 Configure cluster parameters manually
Operation Command Description
Enter system view system-view -
Enter VLAN interface
view
interface Vlan-interface vlan-id Required
The Switch 7750 requires you to
configure the IP address of the
Layer 3 virtual interface of VLAN1
before you set up a cluster.
Otherwise, the cluster cannot be
set up.
Configure the IP
address of the VLAN
interface
ip address ip-address { mask |
mask-length }
Required
Enter cluster view cluster -
Configure an IP
address pool for the
cluster
ip-pool
administrator-ip-address { ip-mas
k | ip-mask-length }
Required
Build a cluster build name Required
The name argument specifies the
name to be assigned to the
cluster. If a cluster is already
established, you can use this
command to change the name of
the cluster.
Configure a multicast
MAC address for the
cluster
cluster-mac H-H-H Required
By default, the cluster multicast
MAC address is 0180-C200-000A.
Set the interval for the
management device
to send multicast
packets
cluster-mac syn-interval
time-interval
Optional
By default, the interval to send
multicast packets is one minutes.
Configure the
holdtime for a switch
holdtime seconds Optional
By default, the holdtime is 60
seconds
Set the interval to
send handshake
packets
timer interval Optional
By default, the interval to send
handshake packets is 10 seconds
