Hi Denis,
Thanks for the input. I have spent time on installing the racktables set up and
created a test environment for myself.
I made lot of progress in connecting to the Cisco Catalyst switch, and I was
able to create a switch object etc.,
But for the 802.1Q, I did not have much success. I was looking into the code as
well to understand, but could not
find some answers.
1. If I am connected to a switch port, how does the port will be configured for
the VLAN ?
2. How does it detect on which port num it is connected and do the settings ?
3. Once the port is known does it use the Get/GetNext or just use the
management login information
to login and set the configuration with commands for the respective switches ?
I am digging into the code, would be glad if some one can give me insights into
the code.
Regards,
Prabhakar

Prabhakar,
what you describe is possible, if you can invest in learning RackTables 802.1Q
feature and its internals. This experience does not come easy, but setups
similar to the one you describe exist. RackTables and GVRP are not compatible,
and SNMP is not used to do the job (this is exaplained in earlier posts this
year). A serious 802.1Q user would need to pull a testlab with a few managed
switches together and learn the basics there in the first turn.
