—Necessary traffic for instance DHCP must be allowed, while all other traffic is denied.

Sample Access Control List

The following is a sample ACL for a voice VLAN named VLAN120.

set security acl ip SpectraLink permit udp 0.0.0.0 255.255.255.255

eq 68 0.0.0.0 255.255.255.255 eq 67

set security acl ip SpectraLink permit udp 0.0.0.0 255.255.255.255

eq 67 0.0.0.0 255.255.255.255 eq 68

set security acl ip SpectraLink permit cos 6 udp 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255 eq 69

set security acl ip SpectraLink permit cos 7 119 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255

set security acl ip SpectraLink deny 0.0.0.0 255.255.255.255 commit security acl SpectraLink

Network management

Network management is as much strategy and process as it is applications. Managing a converged network consists of four key phases:

1Assessment—Network Health Checks and WLAN Site Surveys (post-deployment) are critical assessment items. The main goal is to verify the ability of the network to provide voice at the required Quality of Experience (QoE).

2Predeployment—Before you deploy VoIP handsets, make the network ready by rolling-out QoS across the network. This phase assumes the WLAN itself is already deployed.

3Ongoing monitoring—Regularly monitor the performance of the converged network to ensure that voice quality continues to meet expectations as the network grows and evolves over time.

4Reporting and planning—Keep track of exceptions and problems and form plans to resolve issues. The resolution of problems takes you back through the assessment, predeployment (QoS configuration), and monitoring phases again.

Nortel ties this business cycle together seamlessly with a set of products that provide a comprehensive solution. This solution is comprised of integrated and innovative standards-based technologies, such as Real Time Control Protocol Extended Reports (RTCP-XR) for detailed real-time management of calls in progress. The overall solution is referred to as Proactive Voice Quality Management (PVQM).
