Mld-Snooping Group-Policy - 3Com S7906E Command Reference Manual

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:
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.
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).
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).
