Hi Trungleon,

 

When using multiple ports are trunk/etherchannel the duplex has to be fixed in case of cisco switch or else this type of behaviour shows up I am sure you are aware of it .... but with your comment that the setup is working fine with TMOS 10.2.2 this comment rules out. This problem needs to be addressed properly what exactly is giong on... TMOS 11.1 has problems I will agree to it. If you wish to continue with ver. 11.1 I prefer you better open a case with F5 Support.
