Has an area open to visitors, either in the lobby or in a conference room, that has a hub The scenario assumes that the corporation Two VLANs (voice-vlan and employee-vlan) must be configured on the ports that connectġ92.0.2.32/28 192.0.2.33 through 192.0.2.46 192.0.2.47 is the subnet’s broadcast address This VLAN completely includes the voice VLAN. VLAN standalone PCs, PCs connected to the network through the hub in VoIP telephones, Port, VLAN, and Layer 3 routed firewall filters on the switch.ġ92.0.2.15 is the subnet’s broadcast address This firewall filter is applied to a routed port (Layer 3 uplink module) on the distribution Priority to employee traffic destined for the corporate subnet. Prioritizes employee-vlan traffic, giving highest forwarding-class Router firewall filter, egress-router-corp-class Also prevents guests from using peer-to-peer applications on guest-vlan, but allows guests to access the Web. Prevents guests (non-employees) from talking with employees or employee hosts VLAN firewall filter, ingress-vlan-limit-guest This firewall filter is applied to vlan interfaces on the access switch. Employee traffic destined for the Web is counted and analyzed. VLAN firewall filter, egress-vlan-watch-employeeĪccepts employee-vlan traffic destined for the corporate subnet, butĭoes not monitor this traffic. This firewall filter is applied to VLAN interfaces on the access switch. On the VLAN and all communication between the gatekeeper device and VLAN phones. This firewall filterĪpplies to all phones on voice-vlan, including communication between any two phones That is, all voice-vlan traffic on TCP ports should be destined for the gatekeeper device.

Ports should be used and only the gatekeeper uses HTTP. That manages call registration, admission, and call status for VoIP calls. Prevents rogue devices from using HTTP sessions to mimic the gatekeeper device VLAN firewall filter, ingress-vlan-rogue-block This firewall filter is applied to port interfaces on the access switch. The traffic rate for TCP and ICMP packets is limited to 1 Mbps with a burst size up to Performs rate limiting on packets that enter the ports for employee-vlan. Low delay, low jitter, assured bandwidth, and end-to-end service for all voice-vlan traffic. The forwarding class expedited-forwarding provides low loss, This firewall filter performs two functions:Īssigns priority queueing to packets with a source MAC address that matches the Port firewall filter, ingress-port-voip-class-limit-tcp-icmp Table 1: Configuration Components: Firewall Filters Component
