AutoQos-4.0-VoIP-Data-Cos and AutoQos-4.0-VoIP-Signal-Cos handles those instances when a user
connects an IP phone to an interfac e and enters the auto qos voip cisco-p hone command on that
interface. In this situati on, the input service policy on the interface must match VoIP and signaling
packets based solely on their CoS markings because switching ASICs on Cisco IP Phones are limited to
only remarking the CoS bits of VoIP and signa ling traffic. Matching D SCP markings would result i n a
security vulnerability because a user whose PC was connected to an IP phone connected to a switch
would be able to remark DSCP markings of traffic arriving from their PC to DSCP ef using the NIC on
their PC. This results in incorrectly placing non real-time traffic in the priority queue in the egress
direction.
