Hi,A weird one - all our UCM servers actually have the wrong subnet and default gateway. Original the UCM servers were in a class C subnet which was subsequently subnetted to a /26 range but neither the subnet and gateway were changed to reflect the ...
We are planning to upgrade our Cisco UCM from 11.0 to 12.5. We do have a number of Voice Gateways whose IOS version is below the minimum on the Cisco compatibility matrix (https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/unified/comm...
I really hope someone can point me in the right direction over this one – in one form or another it’s quite longstanding and causing me quite a headache. We are having problems with poor video conferencing performance in various parts of the network...
I've never had to consider this before - but we are migrating remote sites from one network provider to another whilst retaining the same IP address schemes on the sites. We now have the situation where the new providers work around for handling the...
Hi,This is a long one - so bear with me.... This issue has been bugging me for a while now. We have a pair of Cisco 5520 Wifi controllers in a SSO configuration (just upgraded both to 8.5.151.0) and approx 300 APs (mainly a mixture of 3702 & 3802's) ...

Hi, Thanks for the responses - is there a simple explanation with what the qos queue-softmax-multiplier 1200 setting does? On a test switch with a port just setup with auto qos it looks like: BLANKSWITCH#sho pl ha fe sw 1 q q con interface gi1/0/3As...
Thanks for the responses - I will read and digest them in more detail later. We actually gave it a go earlier with our supplier.Our first thing was a suggestion a colleague made of changing the old suppliers ospf cost to something higher (ip ospf cos...
Right - success! Simply adding "no ip redirects" to the VLAN IP interface on the core-vss 6800 switch cured the problem (I also added to the sw-man switch VLAN interface for good measure whilst I was doing it). So far all tests I run from sw-test ha...
Hi,Sorry for the delay as today is my first day back after the Christmas break. I've looked at the solution posted by vb10 and it really does look like that is the root cause. I see that the fact that its the VLAN interface for inbound and outbound i...
