on the management device (this is not true when you add the candidate device to the cluster using

the administrator-address command). 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.

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.

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.

If all the Telnet resources on the requested device are used up, the switching to the device will not

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

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.

Use the cluster-mac command to configure a multicast destination MAC address for HGMPv2 protocol

Use the undo cluster-mac command to restore the default multicast destination MAC address of

HGMPv2 protocol packets.

The default multicast destination MAC address of HGMPv2 protocol packets is 0180-C200-000A.

Note that you can only use this command on a management device.

With the destination MAC address of HGMPv2 protocol packets configured on the management device,

through the multicast MAC synchronization packets, the member devices can learn the multicast MAC

address of HGMPv2 protocol packets and use it to send NDP multicast packets, NTDP multicast

packets, and cluster packets.
