Hello I think I find a bug in ACNS v5.3.3.8 and 5.4.1.9 too : By default the tcp server-mss should be 1460 but in fact it is the same than tcp client-mss, 1432. So to fix it you have to enter manually the comand 'tcp server-mss 1460' after each reboot of the unit. Do you have same problem or it is only my units ? Thanks
