66-3 config mld_snooping multicast_vlan
Description
This command is used to add member ports and source ports to a list of multicast VLAN member
ports. Member ports automatically become untagged members of the multicast VLAN and source
ports automatically become tagged members of the multicast VLAN. If the port list of an existing
multicast VLAN is changed without specifying add or delete, the newly added port list replaces the
existing port list. A member port list cannot overlap with a source port list of the same multicast
VLAN. However, member ports of one multicast VLAN are allowed to overlap with member ports
on a different multicast VLAN.
A multicast VLAN must first be created using the create mld_snooping multicast_vlan command
before it can be configured.
Format
config mld_snooping multicast_vlan <vlan_name 32> {[add | delete] [member_port
<portlist> | [source_port <portlist> | untag_source_port <portlist>] | tag_member_port
<portlist>] | state [enable | disable] | replace_source_ipv6 [<ipv6addr> | none] |
remap_priority [<value 0-7> | none] {replace_priority} | cvid [<vlanid 1-4094> | null]}(1)
Parameters
<vlan_name 32> - Enter the name of the multicast VLAN. The VLAN name can be up to 32
characters long.
add - Specify to add member ports to the multicast VLAN.
delete - Specify to delete member ports to the multicast VLAN.
member_port - A member port or range of member ports to be added to the multicast VLAN.
The specified range of ports will become untagged members of the multicast VLAN.
<portlist> - Enter the list of port to be configured here.
tag_member_port - Specify that the port or range of ports will become tagged members of the
multicast VLAN.
<portlist> - Enter the list of port to be configured here.
source_port - Specify the port or range of ports to be added to the multicast VLAN.
<portlist> - Enter the list of port to be configured here.
untag_source_port - Specify the source port or range of source ports as untagged members of
the multicast VLAN. The PVID of the untagged source port is automatically changed to the
multicast VLAN. Source ports must be either tagged or untagged for any single multicast
VLAN, i.e. both types cannot be members of the same multicast VLAN.
<portlist> - Enter the list of port to be configured here.
state - Used to specify if the multicast VLAN for a chosen VLAN should be enabled or disabled.
enable - Specify to enable the multicast VLAN for a chosen VLAN.
disable - Specify to disable the multicast VLAN for a chosen VLAN.
replace_source_ipv6 - Before forwarding the report packet sent by the host, the source IP
address in the join packet must be replaced by this IP address. If none is specified, the source
IP address will not be replaced.
<ipv6addr> - Enter the replace source IPv6 address here.
none - Specify to remain the original source IP address.
remap_priority - The remap priority value to be associated with the data traffic to be forwarded
on the multicast VLAN. The default setting is none.
<value 0-7> - Enter the remap priority value here. This value must be between 0 and 7.
none - Specify to use the packet's original priority.
replace_priority - (Optional) The packet priority is changed to the remap_priority, but only if the
remap_priority is set.
cvid - Specify the customer VALN ID carrying in MLD query when Q-in-Q function is enabled.
