Hi,
Currently we are experiencing excessive traffic fragmentation between the Foreign and Anchor WLC's.
Due to the fragmentation the firewalls are having a high CPU load and are facing performance issues.
Because of this I've changed the TCP MSS to 1363 but this only takes care of the CAPWAP overhead (AP <-> WLC).
What is the overhead of the EOIP tunnel between the foreign and anchor WLC and are there ways to decrease the MTU size so that there will be no (or less) fragmentation ?
Grtz.
