Parameters

Name	Meaning
OID	ID of a MIB object.
APMAC	MAC address of an AP.
RADIOID	Radio ID.
WLANID	WLAN ID.
APName	AP name.
MaxUserNum	Maximum number of multicast group memberships on a VAP.

Impact on the System

New users cannot join multicast groups.

Possible Causes

The number of multicast users on the VAP exceeds the maximum number of multicast group memberships configured for the VAP.

Procedure

Run the display traffic-profile { all | name profile-name } command to check whether the maximum number of multicast group memberships on the VAP is properly configured.
- If so, the actual multicast traffic is too large, and it is normal that users are prevented from joining multicast groups. No action is required and proceed to Step 5.
- If not, go to Step 2.
Run the igmp-snooping max-user max-user command to set a large value for the maximum number of multicast group memberships on the VAP.
Check whether the alarm persists.
- If so, go to Step 4.
- If not, go to Step 5.
Collect trap, log, and configuration information, and contact technical support personnel.
End.
