Hi Dominik,
thank you for answering. It seems to be a littlebit strange...

The inventory Manager should have the Gbic Information. I saw the tab on a
screenshot of the 2.3 installation which was sent to me by my presales engineer of avaya.
I'm not sure but I could swear I had have the information until the version of 2.2.
Did you checked the checkedbox for collect gbic data at the preference tab in the
inventory manager ? Otherwise it won't collect gbic data.
I put a sniffer on the port of the COM Server and i could see, that there is telnet traffic
asking for gbic information.
Which OS do you running for the COM ?
Cheers
Frank
