[mrtg] Cisco Subinterfaces

[Luis Alejandro Wong]

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.

 encapsulation frame-relay
