[mrtg] Re: Referencing interfaces on Cisco's

[Jason Frisvold]

I understand that they are numbered as the interfaces are created, but how
do I determine which interface was created first on a given router?  I'm not
a perl guru, so I have no idea how cfgmaker does this?

On our Bay routers, everything from ANs to BCNs, the interfaces get numbered
as they're created, so 1:public at bcn2 is the first interface we added to that
router when building its initial config, and 4:public at bcn2 is the fourth.

The problem I see with that is that I need this to be automated...  That's
going to require a lot of extra code that I don't want to write..

Jason
Just do an snmpwalk on the interfaces of your router.
You'll get something like this:

interfaces.ifTable.ifEntry.ifDescr.1 = "FastEthernet0/0"
interfaces.ifTable.ifEntry.ifDescr.2 = "Serial1/0"
interfaces.ifTable.ifEntry.ifDescr.3 = "Serial1/1"
interfaces.ifTable.ifEntry.ifDescr.4 = "Serial1/2"
interfaces.ifTable.ifEntry.ifDescr.5 = "Serial1/3"
interfaces.ifTable.ifEntry.ifDescr.6 = "Ethernet2/0"
interfaces.ifTable.ifEntry.ifDescr.7 = "Ethernet2/1"
interfaces.ifTable.ifEntry.ifDescr.8 = "Ethernet2/2"

i.e. interface 1 is FastEtheret0/0 etc.

Cheers
Luke
