Enabling SVP Optimization for SpectraLink Phones
You can configure WSS Software to prioritize voice traffic for VoIP phones that use SpectraLink Voice Priority (SVP).
If you disable WMM support and enable SVP support, WSS Software 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 wildcard. 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:
23x0# 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:
23x0# 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.
23x0# set security acl ip svp permit 0.0.0.0 255.255.255.255
4 Commit the ACL to the configuration:
23x0# commit security acl svp
5 Map the ACL to the outbound traffic direction of VLAN corp_vlan:
23x0# set security acl map voip vlan corp_vlan out
Security ACL Configuration Scenario
The following scenario illustrates how to create a security ACL named acl-99 that consists of one ACE to permit
incoming packets from one IP address, and how to map the ACL to a port and a user:
1 Type the following command to create and name a security ACL and add an ACE to it.
23x0# set security acl ip acl-99 permit 192.168.1.1 0.0.0.0
2 To view the ACE you have entered, type the following command:
23x0# show security acl editbuffer
ACL Type Status
---------------------------------- ---- -------------
acl-99 IP Not committed
3 To save acl-99 and its associated ACE to the configuration, type the following command:
23x0# commit security acl acl-99
