Skinny Client Control Protocol (SCCP)
When a call-control protocol is detected, the switch assigns the trac in that session to the highest CoS
queue, which is generally used for time-sensitive trac.
auto-voip
Use this command to configure auto VoIP mode. The supported modes are protocol-based and oui-
based. Protocol-based auto VoIP prioritizes the voice data based on the layer 4 port used for the voice
session. OUI based auto VoIP prioritizes the phone trac based on the known OUI of the phone.
When both modes are enabled, if the connected phone OUI is one of the configured OUI, then the voice
data is prioritized using OUI Auto VoIP, otherwise protocol-based Auto VoIP is used to prioritize the
voice data.
Active sessions are cleared if protocol-based auto VoIP is disabled on the port.

auto-voip oui
Use this command to configure an OUI for Auto VoIP. The trac from the configured OUI will get the
highest priority over the other trac. The oui-prefix is a unique OUI that identifies the device
manufacturer or vendor. The OUI is specified in three octet values (each octets represented as two
hexadecimal digits) separated by colons. The string is a description of the OUI that identifies the
manufacturer or vendor associated with the OUI.
