Today when I try to change the Gi1/0/1(routing port) on the fibre module of 3750 into switchport by issuing the "switchport" command, then assign it to a vlan, then I connect it to a fibre module on a nortel layer2 switch. I found out there is no conectivity between the
3750 and the nortel switch. The status of the Gi1/0/1 is "not connected". Is it because I cant do it on a fibre module?
helllo...... no ...u r wrong....if it is 48 ports 10/100/1000 ethernet ......with 4 sfp ports the first SFP port will be Gi/0/1 apart from that 48 ports.i think it is needed to check both ends of the switches for correct match.... like same kind of transceiver are used or not???
We nomally use 3750 as L3 switches, ospf route the traffic between the core switch and the vlans these L3 switches. In this case, we uplink the gi1/0/1 fiber module port to the friber module port of a Nortel470
48 ports L2 switch, then configured the gi1/0/1 as a switchport in a vlan. But the friber module of the Nortel 470 can't communicate with the fiber module of cisco 3750. The fiber we used is sc to lc. We have tried some Nortel450 28 ports switches, they can communicate with the cisco fiber module well. Have no idea of this strange thing, anyone has a clue?
We used multimode fiber between the core switch and these 3720 switches. I think we used single mode fiber for the long distance, such as the one between the boundry router and core switch, but not sure about it. We use both Cat5 and Cat6 patch panels.
