I should have said I'm running cfgmaker like this....


/usr/bin/cfgmaker --enablesnmpv3 --snmp-options=::2:1:1:3 --global
"Options[_]: bits,growright" --global "MaxBytes[_]: 125000000"
- --username=MRTG --ifref=name --ifdesc=alias
- --contextengineid=800007c703000cdbfb5500 --authkey=<mykey> --global
"WorkDir: /var/www/localhost/htdocs/mrtg-tbsh/Switch/THN-BGP-1"
- --privprotocol=des --authprotocol=sha --privkey=<mykey>
- --zero-speed=100000 THN-BGP-1


Cheers,

Dunc
