This sort of switch does support SNMP, so it should work.  You should check
–

1.       Is SNMP community configured correctly on the switch?  You are
using ‘public’ for cfgmaker, is this also defined on the switch?

2.       Is the ACL on the switch configured correctly to allow access from
this IP address with this community?

3.       Are there any firewalls in the way preventing UDP 161 from reaching
the switch?

4.       Do you have a route to the switch at all (try doing a ping to
verify)?

5.       Do you have a firewall on the MRTG server which is blocking the
SNMP reply packets?

6.       Are you using the correct SNMP version – should you use SNMPv2c
instead (your example below is using v1) or SNMPv3?

7.       Is the switch or network so heavily congested that it is slow
replying?  Try increasing timeout and/or retries count using the other
fields in the --snmp-options parameter.

Cfgmaker can not connect to the Switch with Cat OS.  

All other switch with IOS is working.

Betreff: RE: Hilfe

Create a configuration file for MRTG using cfgmaker.  You can use pretty
much the same method to monitor any SNMP switch or router, not just Cisco.
Here is an example using some general options:

cfgmaker --ifdesc=catname,ppname,descr,alias,ip,name,nr --ifref=ip,name,nr
--global=’WorkDir: /var/rrdtool’ --global=’LogFormat: rrdtool’
--global='Options[_]: bits,growright' --show-op-down --output=device.cfg
--snmp-options=:::::2  --community=community   device

Replace ‘community’ and ‘device’ as appropriate.  This will omit interfaces
with a speed of zero or that are administratively down; you can add
‘--no-down’ if you want to graph these anyway.

You can find more information in the cfgmaker documentation; unfortunately
for you it is in English.  I don’t know if there is a German translation
available anywhere
