Hi all, I have a 2940 switch with an SFP based gigabit uplink port. Im plugging it into an Alcatel radio unit, which seems to be reporting that the link is up (there is a tick showing up in the management interface that represents "Port Up" which also goes away when I unplug the fibre), but on the Cisco I see the following:
Switch#sh int gi0/1 GigabitEthernet0/1 is standby mode, line protocol is down (disabled) Switch#sh ip int brief Interface IP-Address OK? Method Status Protocol GigabitEthernet0/1 unassigned YES unset standby mode down Given what I said above about the Alcatel unit, it seems as though perhaps the Alcatel is receiving signal from the Cisco, but the Cisco isnt recognising anything. Have tried different fibre leads, plugging into different devices, different SFPs, but nothing. Does anyone have any idea what "standby mode" means, and whether it could be responsible for this behaviour? Ive done a bit of searching to try and find out what this means, but have so far come accross nothing that helps. Hoping someone here will have some ideas.
