Egress 
Egress denotes the direction of a frame exiting an interface. For outgoing packets the CoS 
marking needs to be translated to mapping understood by the network domains.  
No Egress 
The default Egress page setting. Domain mappings of the packets are not altered 
Layer2 
Enables you to map an outgoing packet to user priority bits which are honoured by 
the VLAN bridged network. Only supported on WAN interfaces. 
Layer3 
Enables you to map CoS to ToS bits so priority marking of outgoing packets work 
properly on IP networks.
