Each command is listed, in detail, in the following sections.
create igmp_snooping multicast_vlan
Purpose
Used to create a multicast VLAN.
Syntax
create igmp_snooping multicast_vlan <vlan_name 32> <vlanid 2-4094> {
remap_priority [ <value 0-7> | none ] { replace_priority } }
Description
The create igmp_snooping command creates a multicast VLAN and implements relevant
parameters as specified. More than one multicast VLANs can be configured. The maximum
number of configurable VLANs is project dependent.
Newly created IGMP snooping must use a unique VLAN ID and name, i.e. they cannot use
the VLAN ID or name of any existing 802.1q VLAN.
Also keep in mind the following conditions:
Multicast VLANs cannot be configured or displayed using 802.1Q VLAN commands.
An IP interface cannot be bound to a multicast VLAN.
The multicast VLAN snooping function co-exists with the 802.1q VLAN snooping function.
Parameters
vlan_name
- The name of the multicast VLAN to be created. Each multicast VLAN is given a
name that can be up to 32 characters.
vlanid
- The VLAN ID of the multicast VLAN to be created. The range is 2 - 4094.
remap_priority
- The remap priority (0 to 7) to be associated with the data traffic to be
forwarded on the multicast VLAN. If none is specified, the packet’s original priority will be
used. The default setting is none.
replace_priority
- Specify that packet’s priority will be changed by the switch, based on the
remap priority. This flag will only take effect when the remap priority is set.
Restrictions
Only Administrator and Operator-level users can issue this command.
