I was troubleshooting some MTU issues on a Cisco 3750 Switch with Advanced IP Services Software. I came across a discussion, for a known bug issue that in order for system MTU to work we have to "downgrade" to IP BASE.
I'm interested in that also. We've had an issue this week with Dell servers running TOE (TCP Offload Engine.) This increases the size of the frame to 128000 Bytes which is fragmented into a lot of frames. On a remote site, connected with 3750's over a LES1000, we get a huge amount of retransmissions, which then reorders and resends the entire 128K frame again making it prolifically slow. It's ok across the local LAN and also from other sites. Trying to find out why this happens here? These switches are 3750 and using Advanced Services???
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...
