SG300 -- filter only IGMP packets for a vlan on a port.

[gwilson]

I have a cisco SG300 that is supporting a multicast tv network.  I'm currently managing the switch on a separate vlan from the tv network, but the interface for the actual iptv devices (SSVI) is unfortunately on the same vlan as the igmp streams.

So, what I'd like to do, is filter the IGMP packets from ever being forwarded on the port going to my management network and pass the http/https traffic.   The IGMP data volume is killing my network when I let it pass, so I have to toggle the membership for very short windows when I need to administer the iptv streams, which is several times a week.

Any ideas?

Can you help clarify the topology for me?

VLAN A has the IPTV streams happening on it.

VLAN B has the management network on it.

You'd like all traffic to stay isolated to VLAN A?

Can you also tell us what the multicast mode is if applicable? Are you running sparse, dense, or sparse-dense, and is this ASM or SSM/BiDir? If it's all layer 2 only, is there anything unusual configured?

I see where my original question could have been better worded.

Here's what I have:

VLAN A = Video Lan, utilizing multicast

VLAN B = Management Network

SG300-Ports 1-8 = VLAN A

SG300-Port 9 = Trunk to another SG300 supporting the the video network

SG300-Port 10 = Trunk to management network

The SVSI devices that make up the network provide their management on VLAN A, as well as the multicast.

What I'd like to have is:

SG300-Port 10 = Trunk (VLAN B, VLAN A [minus IGMP traffic])

I'm not sure which multicast mode the SVSI devices operate in -- I'll have to do some homework there.  However, the SG300 operates as a layer 2 switch.  I hope this helps.
