Hi Mohammed,

Has the port been configured?


Is the cable being used known to be good?

Is this apart of an existing network or yet to be commissioned?

Hi Sam

This controller is already in used.Esa0 is being used and its working fine.
Now I want to use esa1 for the captive portal traffic so when I connected this with switch it is not coming up.

Hi Mohammed,

If you've confirmed the cable and switch ports are good, configured a topology in the GUI for esa1 and there is still no luck then i would advise opening a case with us here at GTAC.

Let's start with the most basic question - which of the below ports have you connected ?
esa1 = #2 = the fibre port

Is the esa1 enabled on the controller GUI > Controller > Network > L2 Ports > checkmark for esa1 is set and it's not in a LAG

Hi Ronald

Attached is the controller GUI L2Ports status esa1 is enable and the cable is connected.
It is not the part of the Lag.

What LAN switch is used and is the fiber port a 10G port ?
Try out esa2 - at least the L2 should go green even without a configuration on the controller.
Have you checked whether rx/tx of the fiber link is correct.
Hi Ronald

LAN switch is Enterasys B5K series and yes the fiber between B5k and core is 10Gig
Tried on all the available ports but no luck.
Yes verified port speed and duplex on both the ends.
