Sorry, but need clarification. Is the debug and output of the local router provided where the sources are and not on the receiver end? If that is the case, the similar information from the receiver side would be helpful.   ... View more

You are making sense and some good troubleshooting on your part. Suggest re-ordering your access list so that the 239.255.255.255 is not denied by the first instance: ! Access-list 10 Permit 239.255.255.255 Permit 239.192.0.0 0.1.255.255 !   ... View more

"spanning-tree bpdufilter enable" disables spanning tree bpdus on an interface. Essentially disabling STP. Which could be an issue if connected to other switches. "spanning-tree portfast edge" allows for the immediate forwarding of packets until STP can run, mainly for purposes of DHCP and access ports. I don't understand your response though. However, if you have portfast on an interface and are concerned about possible BPDUs, then you enable BPDU guard either globally or on an interface basis. ... View more

Hello, Not sure the reasoning behind the way you have things configured, but you have spanning tree turned off on all the interfaces with the "spanning-tree bpdufilter enable" command and from what I can tell the "no ip igmp snooping tcn flood" allows flooding of all multicast packets anytime there's a topology change (for example a port going up and down). So every time you reboot a server or add a new connection, causing a port to go up or down, you're flooding all the ports with multicast traffic and basically creating a broadcast storm. Not to mention any broadcasts that probably compound the issue.   Unless there is a compelling reason, suggest removing the "no ip igmp snooping tcn flood" to see if that improves things, and then the "spanning-tree bpdufilter enable" if possible. Also, if this switch is connected to other network switches, removal of the bpdufilter may require a closer look.   Hope this helps. Hope this helps. ... View more

This sounds more like a STP issue more than anything else. Could you post the switch config and perhaps "sh spanning-tree root"? ... View more

Just out of curiosity, is there a TTL setting associated with the 239.255.255.255 group? If so, and it is set to 0 or 1 then that may be your problem. Set it to something equivalent to the maximum number of hops in your network  and add a couple more just for kicks. Hope this helps. ... View more

I agree with OMZ in that I don't think the IGMP configuration is needed  on the routed interfaces on both the router and switch.  ... View more

Hello,  I did a test and think the password "default" has a space at the end which may be considered a character. So try typing the password followed by a space "default " then hit enter.   Hope this helps ... View more

Have you tried flipping the transmit and receive on one of the fiber jumpers? ... View more

Bit confused, but I assume the translation-profile would include the rule for the translation. Also, I think if applied to the pool it may be "outgoing" and not incoming. I was able to apply the config to one of my routers, but unfortunately can't test it out. ... View more

Not sure if this will work, but have you tried applying the translation profile to the "voice-register pool"? I assume it would only apply in SRST mode. ... View more
