[mrtg] Re: Cisco Subinterfaces

[Stieers, Ken]

Frame relay sub interfaces are accessed using the following OIDs (taken from
mibhelp.txt in the /doc directory of the standard MRTG distribution):

frInOctets => '1.3.6.1.2.1.10.32.2.1.9'
frOutOctets => '1.3.6.1.2.1.10.32.2.1.7'

which when used in the form:

frInOctets.pp.dd&frOutOctets.pp.dd:community at cisco.router
where pp is the physical port that the frame relay pvc is
defined on and dd is the DLCI of the pvc gets you the in
and out octets for just that pvc.

IIRC frame relay is defined in RFC1315.MIB, so you could use the LoadMibs
option and use the symbolic name (frInOctets, etc.)


HTH, 

Ken

Subject: [mrtg] Cisco Subinterfaces


I installed MRTG successfully to monitor our network routers . I ran into a
situation in which I have a Cisco 4700 router which has sub interfaces on
two of the Serial Ports (0 and 1). This subinterfaces go from Serial0 to
Serial 0.5 and from Serial1 to Serial1.5. This subinterfaces are done
because the remote sites are coming in through a framerelay pipe. When I run
cfgmaker, the output file does not show this subinterfaces. It gives me the
configuration for the Serial Port as 1 entity. Does anyone have any
suggestions? Here's a copy of the configuration.
