Procedure

  1. Create the ACL 
    1. On a Cisco switch, the command would be: access-list 100 permit tcp host 192.168.1.9 host 192.168.2.10 eq 1702
  2. Apply the ACL to SVI. 
    1. The Cisco commands would be: 
interfaceVLAN 1		
ip access-group 100 in

The solution is to configure a network switch with an access control list (ACL) so that only the Q-SYS control traffic from LAN A can reach the AV CONTROL network.

  • Control traffic will use TCP port 1702
  • The IP address and submask for Q-SYS LAN A will be 192.168.1.9 255.255.255.0 gateway 192.168.1.1
  • Q-SYS LAN A will be located on VLAN 1(192.168.1.1), and the AV Control network on VLAN 2 (192.168.2.1).
  • The switch will be a layer 3 switch that routes between VLAN 1 and VLAN 2.
  • The ACL will be applied to SVI 1 (VLAN 1)
