Cluster-Mac - H3C s3600 series Command Manual

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
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.
Examples
# Switch from the management device to number-6 member device and then switch back to the
management device.
<aaa_0.Sysname> cluster switch-to 6
<aaa_6.Sysname> quit
<aaa_0.Sysname>

cluster-mac

Syntax
cluster-mac H-H-H
undo cluster-mac
View
Cluster view
Parameters
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 destination MAC address for HGMPv2 protocol
packets.
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.
Since some devices cannot forward the multicast packets with the destination MAC address of
0180-C200-000A, HGMPv2 packets cannot traverse these devices. For a cluster to work normally in
this case, you can modify the multicast destination MAC address of HGMPv2 protocol packets without
changing the current networking.
