If you are upgrading a switch running MSS Version 3.x to MSS Version 4.x, and the switch uses ACLs to map VoIP traffic to CoS 4 or 5, and you plan to leave WMM enabled, 3Com recommends that you change the ACLs to map the traffic to CoS 6 or 7.

You must map the ACL to the outbound traffic direction on a MAP port, Distributed MAP, 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 MAP, or user glob. You do not need to disable WMM support.

Enabling VoIP To enable VoIP support for TeleSym packets, which use UDP port 3344, Support for TeleSym for all users in VLAN corp_vlan, perform the following steps:

VoIP

1Configure 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:

WX4400# set security acl ip voip permit cos 6 udp any eq 3344 any

2Configure 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.
