2.3.4 Checking the Configuration

Prerequisite
The configuration of multicast VLAN replication is complete.
Procedure
l
----End
Example
Run the display multicast-vlan vlan [ vlan-id ] command to view information about a multicast
VLAN.
<Quidway> display multicast-vlan vlan 3
Multicast-vlan
User-vlan Number
IGMP snooping state
MLD
User-vlan
Issue 01 (2011-07-15)
NOTE
On the S2700EI, a user-side interface must be added to the multicast VLAN and user VLAN in the same
mode.
CAUTION
If the network-side interface is added to a user VLAN, a traffic policy needs to be configured
on the network-side interface to prevent the IGMP Query packets destined for the user
VLAN from being sent to the CPU because the IGMP Query packets will overload the
S2700 CPU. For example, if VLAN 1000 is the multicast VLAN and GE0/0/1 is the
network-side interface, run the following commands:
<Quidway> system-view
[Quidway] acl 3000
[Quidway-acl-adv-3000] rule 5 permit igmp
[Quidway-acl-adv-3000] quit
[Quidway] traffic classifier other_vlan operator and
[Quidway-classifier-other_vlan] if-match acl 3000
[Quidway-classifier-other_vlan] quit
[Quidway-classifier-mvlan] if-match vlan-id 1000
[Quidway-classifier-mvlan] if-match acl 3000
[Quidway-behavior-other_vlan] deny
