The interface description in SNMP should be the unique name of the interface as used in the configuration. The Dell switch seems to use the same name for every port. This makes locating the index of a port by its interface name quite difficult without using the MAC address as a go-between.

 

Here is an excerpt of snmpwalk output from a Cisco 3560 running a 12.2 IOS:

 

.1.3.6.1.2.1.2.2.1.2.10101 = STRING: GigabitEthernet0/1
.1.3.6.1.2.1.2.2.1.2.10102 = STRING: GigabitEthernet0/2
.1.3.6.1.2.1.2.2.1.2.10103 = STRING: GigabitEthernet0/3

 

Here is the same command run against a Dell 3524 running 1.0.1.6 Firmware:

 

.1.3.6.1.2.1.2.2.1.2.1 = STRING: Ethernet Interface
.1.3.6.1.2.1.2.2.1.2.2 = STRING: Ethernet Interface
.1.3.6.1.2.1.2.2.1.2.3 = STRING: Ethernet Interface

 

These interface names are not configurable anywhere on the command line that I can find. This is something that should be addressed in a firmware update. If I am missing something, please let me know.

 

Thanks,
