ICX 6450 SFP port blocking
« on: May 15, 2014, 03:58:35 PM »
Hey guys,
 
This is my first time configuring an ICX 6450. I want it to act as a stand alone, non-stacked switch. I want to use port 1/2/1 as the tagged port communicating back to our core SX800 switch on vlan 34. I have set the speed on all 4 SFP ports to 1GB. I disabled STP on port 1/2/1, and it is not a stack member (as best I can tell). The vlan itself is properly configured because tagging port 1/1/1 (copper) gives me a working connection back to our SX800. However, I get no connection when I try with fiber on 1/2/1 (it is also tagged in vlan 34), and a show int lists the port state as BLOCKING. What do I need to do to change the state to FORWARDING?
 
Here is the SHOW INT E 1/2/1

I finally figured out the issue. STP was enabled on the copper port I tagged. Apparently, STP is enabled by default on the ICX series. Definitely a "gotcha!" I wasn't aware of with the ICX.
