Mapping SNMP interface index to interface name

Joe,

 

The BIG-IP that I have has the following mapping:

 

 

SNMP index Interface name

 

16 10/100 ports 1 - 16 "1.1" - "1.16"

 

2 Gigabit ports 17 - 18 "2.1" - "2.2"

 

1 Mgmt port 19 "3.1"

 

 

Is there a some pattern to naming & numbering of these interfaces that I can take advantage of??

 

For example, in the above mapping, couldn't we tell 17 had to map to "2.1" as there is no "1.17"??

 

Thanks,

 

Karthic.
