Can someone help me understand this better., I'm clearly missing something. Why is the default MSS (536) so much smaller than the default MTU (1500)? I would expect them to have a difference of the 40 bytes to account for IP and TCP headers? What am ...
I currently have cisco 3560's sitting behind sonicwalls and all VPN'ing back to my main office in a hub and spoke layout. This same setup is used in about 20 offices, all having between 1-4 POE 3560 switches with IP Phones (7961s) followed by Worksta...
I have a few dozen switches (3560's) that I am logging into to make some changes such as passwords, logging etc. I would then like to copy the new config to my tftp server. I am pasting all the command in while in global config mode, but then I have ...
Thanks Joe. I went back and looked. The question was about minimizing fragmentation and was specific to traffic originating from the router having a default MSS of 536 as you have said( considering the 40 for headers). For anybody trying to follow al...
Thank you Joseph, that helps get me a little closer to understanding. The background on this question is that I’m studying for my CCNP. In the Boson practice test there’s a question about sending a ping at 1500 Bytes with the DF but set through a GRE...
I’m asking a specific question. The default MSS on a Cisco router is 536 Bytes according to Cisco documentation. The default MTU is 1500. Why the huge discrepancy? I’ve read everything you’re posting, the answer isn’t there.
