Cisco – How to disable multicast on a single port

ciscomulticastswitch

We just finished deploying 2 SG300-28 switches in our network. We're building a voLANte video distribution network, so all ports were enabled to have multicasting support.

The problem we face is that our Crestron AV2 doesn't support Multicasting. Do any of you know how to disable multicasting on a single port?

Here's the running config if it matters

no spanning-tree
interface port-channel 1
description Default
exit
bridge multicast filtering
vlan database
default-vlan vlan 999
exit
vlan database
vlan 1 
exit
voice vlan oui-table add 0001e3 Siemens_AG_phone________
voice vlan oui-table add 00036b Cisco_phone_____________
voice vlan oui-table add 00096e Avaya___________________

voice vlan oui-table add 00d01e Pingtel_phone___________
voice vlan oui-table add 00e075 Polycom/Veritel_phone___
voice vlan oui-table add 00e0bb 3Com_phone______________

interface vlan 999
ip igmp query-interval 30 
ip igmp last-member-query-interval 100 
exit
interface range  gi1-28
bridge multicast unregistered filtering 
exit
ip igmp snooping vlan 999 querier 
ip igmp snooping vlan 999 querier address 192.168.1.254 
interface vlan 999
ip address 10.10.10.2 255.255.255.0 
exit
ip default-gateway 10.10.10.1
interface vlan 999
no ip address dhcp 
exit
no boot host auto-config
no bonjour enable
hostname switchb18a77
no snmp-server server

It appears to me as though this would be called "Unicast and Multicast Flood Blocking"

Best Answer

For future reference, I think the option you are looking for may be 'Unregistered Multicast' filtering on the SG300s. (I tried the previous answer's suggestion but that wasn't enough to help in itself for me)

I just had a Meraki router which was for some reason, subscribing to our Symantec Ghost Multicast sessions, not ideal! Setting Unregistered Multicast to Filtering for the port it was connected to sorted the issue and allowed us to get better Ghost performance too.
