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

Network management
Network management is as much strategy and process as it is applications.
Managing a converged network consists of four key phases:
1 Assessment—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).
2 Predeployment—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.
3 Ongoing 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.
4 Reporting 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).
