Enabling Prioritization for Legacy Voice over IP
MSS supports Wi-Fi Multimedia (WMM). WMM support is enabled by default and is
automatically used for priority traffic between WMM-capable devices.
MSS also can provide prioritization for non-WMM VoIP devices. However, to provide priority
service to non-WMM VoIP traffic, you must configure an ACL to set the CoS for the traffic.
The AP maps this CoS value to a forwarding queue.
• If you plan to leave WMM enabled, use an ACL to set the CoS for any type of
non-WMM VoIP wireless traffic to 6 or 7.
• If you plan to disable WMM, set the CoS for SVP traffic to 6 or 7, but set the CoS
for other types of non-WMM VoIP traffic to 4 or 5. When WMM is disabled, the AP
forwarding queue that maps to CoS values 6 and 7 is optimized for SVP.
You must map the ACL to the outbound traffic direction on an AP port, Distributed AP, or
user VLAN. An ACL can set a packet’s CoS only in these cases.
You can enable legacy VoIP support on a VLAN, port group, port list, virtual port list,
Distributed AP, or user glob. You do not need to disable WMM support.
For example, to enable VoIP support for TeleSym packets, which use UDP port 3344, for all
users in VLAN
corp_vlan
, perform the following steps:
1.
Configure an ACE in ACL
voip
that assigns IP traffic from any IP address with
source UDP port 3344, addressed to any destination address, to CoS queue 6:
DWS-1008#
set security acl ip voip permit cos 6 udp 0.0.0.0 255.255.255.255
eq 3344 0.0.0.0 255.255.255.255
2.
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 voip permit 0.0.0.0 255.255.255.255
3.
Commit the ACL to the configuration:
