Hi,Im in the process of upgrading out routers, and ive upgraded a couple of them to 15.6-3.M7 without issue. (c2900-universalk9-mz.SPA.156-3.M7)However my first attempt with 15.6-3.M7 went horribly wrong. As there is very little to go on, i guess thi...

I feel this probably has a obvious easy answer, but struggling a bit. PBX is 172.31.213.130 The public IPs are completely public and cinnected to our ISP.At a branch office they are setting up a PBX box that we have assigned to a vlan. But cant get p...

Hi, We have a bunch of 2911 and 4331 (and a few 2800 left) routers in branch offices around the world. Is there a way to get these routers to log when port errors occur? Like any input/output interface errors, especially CRC/FCS? Or is the only optio...

Thanks.But that does not solve the crashes and lack of LAN connectivity. I would think 44mb should be plenty, at least it has on other routers we've upgraded. Deleting the old image is something we do after about a week of stable operation on the new...

Thanks,Well its not really straight forward for me to test other versions. I do know 15.6-3.M7 worked ok on other routers (same hardware) with similar config. This one is slightly different than other branch routers as it has a SD-wan connection to H...

We simply removed the "match protocol sip" and let it default to "match protocol udp" for outgoing. There are apparently quite a few problems with inspecting SIP with ZBFW
