Required your valued clarification on a basic and a stupid question I have. I hope you dont mind to reply.
I have installed an etheral in one of my LAN broadcast domain where I am getting around 40 to 70 percent UDP traffic of my total subnet traffic.
Need your esteemed advice on this.. I personaly guess its normal. Does it ? I have mostly use of internet. I have a SNMP server in this subnet, HSRP is also configured for this subnet. Please advice. When I figure out this traffic it explains me about the listed protocols that works on UDP.
For the past two weeks we had the case where, a server was broadcasting UDPs We just found the source problem) and our CAT4506 was pegged at 95% (show processes CPU) Cat4k Mgmt LoPri was 85.29% ! The SysAdmmin says we need to close or filter UDP Destination Port 6669 on our Cat3560 (first level Switch) or or Router (4506)
Thank we mployed this on the 4506, we are now down to 10 to 17% !
It was very hard intially to find the source of the problem. I wished I had some software to alert me. As it happened someone remembered complaint from a particular server from months agao, and it was the same problem here.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
