[mrtg] MRTG on Windows NT (trying to listen to Cat.4006 VLans)

[Emre Sümengen]

I am trying to listen the traffic on some VLans created on the Catalyst 4006 switch. I have found the following sample config that is said to work. It does not return any errors but Mrtg does not show any I/O either.
Target[4006_btm_vlan]:1.3.6.1.4.1.9.2.2.1.1.44.11&.1.3.6.1.4.1.9.2.2.1.1.45.11:public at switch_ip

Information about the current switch config is as follows;

4006_Switch#sh vlan id 11
VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------

Any suggestions how to configure MRTG for this VLan?
