[mrtg] Re: Catalyst 6509 - Gigabit traffic monitoring

Hello All,

According to our knowledge you got the problem that the MSFC card will only
show the call setup and that the traffic itself is 'bridged' (it uses
MLS=Multi Layer Switching). So you won't be able to view the required data.
We're still looking for alternatives.

Hi,
I must use SNMP version 2 for Gigabit Interfaces.
This is My piece of config from Catalyst 4000:
Target[router1.xxx.cz_2_4]: #2/4:public at router1.xxx.cz:::::2

> Target[10.40.0.1_6]: 6:public at 10.40.0.1:

For generating configuration I use cfgmaker with these additional options:
--ifref=name    --snmp-options=:::::2

Best Regards,

Pavel Ruzicka
