config igmp_snooping multicast_vlan
Purpose
Used to configure the parameter of the specific multicast VLAN.
Syntax
config igmp_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_ip <ipaddr> | remap_priority
[<value 0-7> | none] { replace_priority}}(1)
Description
This command allows you to add a member port, a tagged member port, a untagged source
port and a source port to the port list. The member port and the untagged source port will
automatically become the untagged members of the multicast VLAN, the tagged member
port and the source port will automatically become the tagged members of the multicast
VLAN. To change the port list, the Switch will add or delete the port list that user entered,
and update the previous port list.
The member port list and source port list cannot overlap. However, the member port of one
multicast VLAN can overlap with another multicast VLAN. In different multicast VLAN, the
source port and untagged source port can not overlap, the member port and source port can
not overlap too.
Before configuring the multicast VLAN member port by using this command, the multicast
VLAN must be created first.
Parameters
<vlan_name32>
−
The name of the VLAN to be created. Each multicast VLAN is given a
name that can be up to 32 characters.
member_port
– Adds a range of member ports to the multicast VLAN. They will become the
untagged member port of the IGMP multicast VLAN.
source_port
– Adds a range of source ports to the multicast VLAN.
untag_source_port
– Adds a range of untagged source ports to the multicast VLAN.
tag_member_port
– Specifies the tagged member port of the IGMP multicast VLAN.
state
– enable or disable multicast VLAN for the chosen VLAN.
replace_source_ip
– With the IGMP snooping function, the IGMP report packet sent by the
host will be forwarded to the source port. Before the forwarding of the packet, the source IP
address in the join packet needs to be replaced by this IPv4 address.
remap_priority
– Associates the remap priority value (
0
to
7
) with the data traffic and is
forwarded on the multicast VLAN. If
none
is specified, the packet’s original priority will be
used.The default setting is
none
.
Restrictions
Only Administrator and Operator and Power-User-level users can issue this command.
Example usage:
To configure an IGMP snoop multicast VLAN:
DES-3528:admin# config igmp_snooping multicast_vlan v1 add member_port 1,3 state
enable
Command: config igmp_snooping multicast_vlan v1 add member_port 1,3 state enable
Success.
DES-3528:admin#
show igmp_snooping multicast_vlan_group
Purpose
Used to display the multicast groups configured for the specified multicast VLAN.
Syntax
show igmp_snooping multicast_vlan_group {< vlan_name 32> }
Description
This command is used to display the multicast groups configured for the specified multicast
VLAN.
Parameters
vlan_name
−
The name of the multicast VLAN to be configured, each multicast VLAN is
given a name that can be up to 32 characters.
Restrictions
None.
