Hello,
On my Cisco 6500 i am getting error message :
039454: May 4 12:40:31.985 IDT: %MCAST-SP-3-QUERY_INT_MISMATCH: Snooping Querier received a non-matching query interval (125000 msec),
from querier address (192.168.254.254) on VLAN(85).Configured query-interval (60000 msec) .
information from sniffer :
13:28:04.562411 b2:c3:88:76:11:cc > 01:00:5e:00:00:01, ethertype IPv4 (0x0800), length 60: 192.168.254.254 > 224.0.0.1: igmp query v3 [max resp time 10s]
interface : Gi3/4
How can i create access list that prevent connection to the destination mac address : 01:00:5e:00:00:01 (igmp connection as u can see in the sniffer output).
thanks.

Hi,
thanks for the reply.
the multicast traffic came from this port :
interface GigabitEthernet3/4
switchport
switchport access vlan 85
switchport mode access
logging event link-status
spanning-tree bpdufilter enable
what i need to do ?
thanks !

Theres a couple of things you can try depending what your IOS supports
Whats connected to that port ,just wondering as see bpdufilter on it
1 switchport block multicast under the interface
2 IGMP filter block the actual multicast address on the port from communicating with igmp snooping examples in doc below

3 Use a mac access-list

4 Turn off multicast traffic on the edge device if its not required and causing issues
