    Using SPF port for Trunk not working

    ianober New Member

      I am trying to connect one of the XGIG ports on my 1550-48P to a Cisco gig port as a trunk connection.  I have both ports configured for trunking and allowing all VLANS for now and I cannot get the 1550 port to light up.  THe Cisco port sees the connection and auto negotiates the connection but the 1550 shows nothing, no link light at all.  I am using 10/100/10000 BaseT SFP modules and the Adtran recognizes them as OEM compatible when they are plugged in but they are not lighting up when connected to the Cisco.


      Any suggestions?
