Configuring and Managing Security ACLs 377

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:

1Disable 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

2Configure 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

3Configure 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

4Commit the ACL to the configuration:

23x0# commit security acl svp

5Map 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-99that consists of one ACE to permit incoming packets from one IP address, and how to map the ACL to a port and a user:

1Type 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

2To view the ACE you have entered, type the following command:

23x0# show security acl editbuffer

3To save acl-99and its associated ACE to the configuration, type the following command:

23x0# commit security acl acl-99
