Enabling SVP Optimization for SpectraLink Phones
You can configure MSS to prioritize voice traffic for VoIP phones that use SpectraLink Voice
Priority (SVP). If you disable WMM support and enable SVP support, MSS ensures voice
quality for SpectraLink phones using SVP by allocating CoS queues 6 and 7 on the MAP
for distinct SVP treatment as well as forwarding all traffic from that queue before forwarding
traffic from other queues.
You can enable SVP optimization on a VLAN, port group, port list, virtual port list, Distributed
AP, or user glob. To enable SVP optimization, disable WMM support on the radio profile that
serves the SVP users, configure an ACL that assigns traffic for IP protocol 119 to CoS queue
6 or 7, and map the ACL to the outbound traffic direction.
For example, to enable SVP support for all users in VLAN corp_vlan, perform the following
steps:
1. Disable WMM support on the radio profile that will serve SVP users, to enable SVP
optimization on AP forwarding queues 6 and 7 for radios managed by that radio
profile:
DWS-1008# set radio-profile radprofsvp wmm disable
2. Configure an ACE in ACL svp that assigns IP protocol 119 traffic for all source and
destination addresses to CoS queue 7:
DWS-1008# set security acl ip svp permit cos 7 119 0.0.0.0 255.255.255.255
0.0.0.0 255.255.255.255
3. Configure another ACE to change the default action of the ACL from deny to permit.
Otherwise, the ACL permits only voice traffic that matches the previous ACE and
denies all other traffic.
DWS-1008# set security acl ip svp permit 0.0.0.0 255.255.255.255
4. Commit the ACL to the configuration:
DWS-1008# commit security acl svp
5. Map the ACL to the outbound traffic direction of VLAN corp_vlan:
DWS-1008# set security acl map voip vlan corp_vlan out
