Hello everyone,     
    I have a  problem with my switch configuration, the topology is the next:
    In the  ports 1-4 are my servers of videoconferencing and the ports 45-46 are the  gateways to two junipers.
    In the  ports 25-28 are two Cisco VCS’s and a Dell Server, ports 47-48 are the gateways  to the local core.
    The configuration  is the following:
    show conf

    My question  is that my switch can reach everyone and vice versa, but the servers of  videoconferencing can’t reach no one of the switch. I already try with LLDP,  LACP, even EDP, and no luck, is there some other protocol to try or what can I do?  I really appreciate all your help.
