A. The 2950 with the EI supports Layer 2 (L2)–Layer 4 (L4) classification at ingress with use of: • Port trust states • QoS access control lists (ACLs) • Class maps and policy maps The 2950 with EI also supports policing and marking at ingress as well as queuing and scheduling at egress. You can configure egress scheduling as either strict priority scheduling or weighted round-robin (WRR) scheduling. Refer to the Release Notes for the Catalyst 2955, Catalyst 2950, and Catalyst 2940 Switches, Cisco IOS Release 12.1(22)EA4 for hardware and software compatibility. In Cisco IOS Software Releases 12.0, EI only supports configuration on class of service (CoS) priorities and WRR.
