decimal values. In version 2.x.x, TCP/UDP port value entries are in decimal value. However - if the user upgrades the
switch firmware from version 1.x.x to version 2.x.x, the value will be retained as hexadecimal value.
ACLs access rules priority did not work in firmware version 1.x.x. In firmware version 2.x.x, the priority is supported and it
is not allowed two identical access rules priority from different access profiles. If the user download configuration file from
version 1.x.x which including ACLs which has more than one rule, it might not work and there will be an error message.
The user can delete and create the ACLs again if he encountered a problem.
Tacacs/Radius backwards compatibility issue - In firmware version 1.x.x, it is possible to configure up to 4 Tacacs /Radius
servers. In firmware version 2.x.x, it is possible to configure up to 3 servers from each type. In addition to that it was not
required to configure priority to Tacacs servers in 1.x.x while in 2.x.x it is required. If the user configured 4 servers in
version 1.x.x and try to download the configuration to firmware 2.x.x, he will get an error message, the same event will
happened because of the Tacacs priority.
