Determining Circuit Numbers
Whenever you create a new circuit via the Technician Interface or the
Configuration Manager tool, the router operating system software (GAME) maps
the circuit name you assign (such as E21) to a circuit number (such as 4) in the
router’s active MIB.
When you use the Technician Interface
ip
command to display data pertaining
only to a specific circuit on a router, you must enter the circuit number after the
-c
option flag for that command.
Example:
The following
ip
command displays all IP routes accessible via circuit 4 on the
router. The command shows the contents of the cache for an unnumbered IP
interface on circuit 4.
ip cache 0.0.0.0 -c4
You can determine the circuit number from the router’s active MIB by using the
Technician Interface
get
command in a variety of ways.
Example
The following command retrieves the circuit number (attribute 6) for every entry
in the FDDI Line_Table:
$ g wfFddiEntry.6.*
wfFddiEntry.wfFDDICct.5.1 = 1
The table has a single line entry.
Example
The following command retrieves the circuit number (attribute 6) for every entry
in the CSMACD Line_Table:
$ g wfCSMACDEntry.6.*
wfCSMACDEntry.wfCSMACDCct.2.1 = 3
wfCSMACDEntry.wfCSMACDCct.2.3 = 2
