Quick question for you....over the weekend we did a hot cut from one location to another it went ok but later found out that if we send anything over 1475 the packets will not be sent, we double checked the routers and mine are set to 1500 the providers are set to 1700 but if we send anything more than 1475 it fails any ideas...also if I set my router to 1400 what is the possibilities of locking myself out of the router?
I've also experienced problems with the IOS prefragmentation not correctly dynamically fragmenting packets utilizing the MSS as part of the decision. I highly recommend setting the TCP MSS to 40 bytes your MTU.
The problems I've had manifest themselves as application issues. Users complain of slowness, and pieces of some applications simply don't work. I had a web page which failed to load all of the images. Once I did a bit of research and set the MSS everything worked.
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...
