    Port Security For device plugged into phone

    getzjd New Member

      Hello,

       

      I am trying to enable basic port security that permits a phone but denies anything else either plugged into the passthrough on the phone or direct to the wall.  The configuration below successfully blocks a device plugged directly into the wall jack in place of the phone, however, if I plug a device into the passthrough on the phone, it is allowed on.  Our phones first boot off of VLAN1, then switch to VLAN 30.  What did I miss?

       

       

      interface switchport 0/21

        spanning-tree edgeport

        no shutdown

        switchport mode trunk

        switchport voice vlan 30

        qos trust cos

        switchport port-security

        switchport port-security maximum 2

        switchport port-security mac-address 00:10:49:0e:4c:c5 vlan 1

        switchport port-security mac-address 00:10:49:0e:4c:c5 vlan 30
