[c-nsp] IGMP snooping/multicast on cisco SGE2010p

[Craig]

Hi. I have a cisco sge2010p small business switch I'm trying to get working
with IGMP (for Windows Deployment Services imaging on 2008r2). This is a
simple single-segment lan; no multicast router. This is the only switch. I
cannot get the switch to stop sending the multicast to all ports (effectively
a broadcast storm). The switch is brand new and updated 2 weeks ago to latest
firmware. I have tried using the switch's querier and also windows' rras IGMP
but neither fixes the broadcast storm kills everything.

In the below configuration, I set the vlan ports to igmp filtering (looks like
i skipped port 24 by mistake). When set to filtering the multicast sessions
cant even get started. When in forwarding mode you get the flood.

Any help would be very very much greatly appreciated.



Cisco-sw1# sh run
bridge multicast filtering
ip igmp snooping
interface vlan 1
ip igmp snooping
exit
interface range ethernet 1/g(1-23,25-47)
bridge multicast unregistered filtering

ip igmp snooping querier enable

interface vlan 1
ip address dhcp
exit

Cisco-sw1# sh ip igmp snooping int 1
