igmp v2 packets generated by extreme summit x460-24t switch

hi,

In extreme switch i have configured vlan 104 on ports 19 and 20 with lacp.

This is the setting

configure vlan vlan104 tag 104
enable sharing 19 grouping 19-20 algorithm address-based L2
configure vlan vlan104 add ports 19, 21-24 tagged
configure vlan vlan104 ipaddress 172.16.3.1 255.255.255.0
enable ipforwarding vlan vlan104
configure vlan vlan104 dhcp-address-range 172.16.3.2 - 172.16.3.200
configure vlan vlan104 dhcp-options default-gateway 172.16.3.1
configure vlan vlan104 dhcp-options dns-server 196.1.105.47
enable dhcp ports 19, 21-24 vlan vlan104

this is current situation

I notice that switch periodically generated IGMP v2 packets membership query and report packets.
How can I avoid their generation ?
Also there is an EDP packet which has no mac or ip address . What is its purpose ?

Thanks.

I tried 'disable igmp' and it worked.
Thanks.

You can try disabling igmp on the vlan in question with the "disable igmp <vlan>' command.

Below is more information regarding EDP which can also be disabled on a per port basis with "disable edp port <port>":
