FCX648-FCX-4XG 10g ports ports linking to Ti24x issues?

Issues connecting ports 1/2/1 and 1/2/2 to a Ti24x  ; They link however no full bi-directional traffic.  

 

Ports 1/2/3 and 1/2/4 work as expected.  This is a non-stacking FCX switch.  I'm curious if this is a bug or similar?

 

I had ports 1/2/1 and 1/2/2 before connected to a RX-8 and had no issues when I went to migrate those ports to a Ti24x had issues with regards to bidirectional traffic.. It almost seems as if this is a problem between the FCX and the Ti24x ;  FDP neighbor information was seen only in 1 direction not both directions; Never any input on the Ti24x side from the remote switch(FCX648.  Has anyone ever ran across this issue or does anyone have equipment to test with?

For FCX-E and FCX-I devices, ports 1 and 2 of the optional 10 Gbps SFP+ module (slot 2) act as the default stacking ports. You should turn off stacking to use these ports for data.

 

Brocade(config)#int e 1/2/1
Brocade(config-if-e10000-1/2/1)#longpreamble

Brocade(config)#int e 1/2/2
Brocade(config-if-e10000-1/2/2)#longpreamble

 

Thanks

I'll try this.  The weird part is that I had ports 1/2/1 and 1/2/2 working with the same configuration to a RX-8, it was just when moving it to a Ti24x did I encounter the problem... I'll update once again when tested with the long-preamble setting on the ports 1/2/1 and 1/2/2 towards a Ti24x.  Thanks again!
