    I have a Cisco Catalyst 3508G-XL-EN, with a firmware of 12.0(5.1)XW Maintenance Interim. I have been able to get it to pass traffic through the GBICs, except for one line. This is an ethernet cable plugged into a WS-G5482 GBIC Transceiver. No matter which port I plug it into, once I put in the no shutdown command the port will go up and then down immediately. Would there be something in the Maintenance Interim that could be stopping this, or is there something else I need to do to make the port stay up.
