Hello, I need to change the name of the port SNMP String. 
With the command "configure ports 1:3 display-string tester" a string of port really changed, but when I look at the values SNMPWalk return: 
IF-MIB :: ifDescr.1003 = STRING: Stack Port 1: 3 
What is the command to change this string for example "Stack Port 1: 1" to "tester"
