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.
Related commands: cluster-mac syn-interval.
Examples
# Configure multicast MAC address 0180-C200-0028 for HGMPv2 protocol packets.

Syntax
cluster-mac syn-interval time-interval
View
Cluster view
Parameters
time-interval: Interval to send 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.
HGMPv2 multicast MAC synchronization packets are used for synchronizing the HGMPv2 multicast
MAC address configuration (configured through the cluster-mac command) between devices in a
cluster, so that HGMPv2 protocol packets can be forwarded normally within the cluster. HGMPv2
multicast MAC synchronization packets are Layer 2 multicast packets.
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.
Related commands: cluster-mac.
Examples
# Set the interval for the management device to send HGMP V2 multicast MAC synchronization packets
to one minute.
