View
Ethernet interface view, Layer 2 aggregate interface view, port group view
Default Level
2: System level
Parameters
limit: Maximum number of IPv6 multicast groups that can be joined on a port. The value is in the range
1 to 512.
vlan vlan-list: Defines one or multiple VLANs. You can provide up to 10 VLAN lists, by each of which
you can specify an individual VLAN in the form of vlan-id, or a VLAN range in the form of start-vlan-id to
end-vlan-id, where the end VLAN ID must be greater than the start VLAN ID. The effective range of a
VLAN ID is 1 to 4094.
Description
Use the mld-snooping group-limit command to configure the maximum number of IPv6 multicast
groups that can be joined on a port.
Use the undo mld-snooping group-limit command to restore the default setting.
By default, maximum number of IPv6 multicast groups that can be joined on a port is 512.
Note that:
z
You can also use the mld group-limit command to limit the number of IPv6 multicast groups that
can be joined on an port. If you configure a limit of the number of groups for ports in a VLAN while
you have configured a limit of the number of groups for the VLAN interface, or vice versa, this may
cause inconsistencies between Layer 2 and Layer 3 table entries. Therefore, it is recommended to
configure a limit of the number of groups only on the VLAN interface.
z
If you do not specify any VLAN when using this command in Ethernet porti view or Layer 2
aggregate port view, the command will take effect for all VLANs the port belongs to; if you specify a
VLAN or multiple VLANs, the command will take effect only if the port belongs to the specified
VLAN(s).
z
If you do not specify any VLAN when using this command in port group view, the command will
take effect on all the ports in this group; if you specify a VLAN or multiple VLANs, the command will
take effect only on those ports in this group that belong to the specified VLAN(s).
