Catalyst 3750 Series 48 Port Managed Gigabit POE Network Switch WS-C3750G-48PS-S
The Cisco Catalyst 3750G Integrated Wireless LAN Controller integrates wireless LAN controller functions into the Cisco Catalyst 3750G Series Switches and delivers improved operating efficiency and WLAN security, mobility, and ease of use for business-critical wireless LANs. The Cisco Catalyst 3750G Integrated Wireless LAN Controller delivers centralized security policies, wireless intrusion prevention system (IPS) capabilities, award-winning RF management, QoS, and Layer 3 fast secure roaming for WLANs. As a core component of the Cisco Unified Wireless Network, the Cisco Catalyst 3750G Integrated Wireless LAN Controller provides the control, security, redundancy, and reliability that network managers need to scale and manage their wireless networks as easily as they scale and manage their traditional wired networks.

Table below shows more informations.
● Cross-stack QoS allows QoS to be configured across the entire stack.
● 802.1p class of service (CoS) and differentiated services code point (DSCP) field classification is provided, using marking and reclassification on a per-packet basis by source and destination IP address, source and destination MAC address, or Layer 4 Transmission Control Protocol/User Datagram Protocol (TCP/UDP) port number.
● Cisco control-plane and data-plane QoS ACLs on all ports help ensure proper marking on a per-packet basis.
● 4 egress queues per port help enable differentiated management of up to 4 traffic types across the stack.
● Shaped Round Robin (SRR) scheduling helps ensure differential prioritization of packet flows by intelligently servicing the ingress queues and egress queues.
• Weighted Tail Drop (WTD) provides congestion avoidance at the ingress and egress queues before a disruption occurs.
● Strict priority queuing helps ensure that the highest-priority packets are serviced ahead of all other traffic.
● There is no performance penalty for highly granular QoS capability.
|Granular Rate Limiting||
● Cisco committed information rate (CIR) function provides bandwidth in increments as low as 8 Kbps.
● Rate limiting is provided based on source and destination IP address, source and destination MAC address, Layer 4 TCP/UDP information, or any combination of these fields, using QoS ACLs (IP ACLs or MAC ACLs), class maps, and policy maps.
● Asynchronous data flows upstream and downstream from the end station or on the uplink are easily managed using ingress policing and egress shaping.
● Up to 64 aggregate or individual policers are available per Fast Ethernet or Gigabit Ethernet port.
