VLAN-based: prioritises traffic by specifying a VLAN & priority level. Class of Service (Co S): sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (To S), Layer 3 protocol, TCP/UDP port number, source port, & Diff Serv Rate limiting: sets per-port ingress enforced maximums for all ingressed traffic or for broadcast, multicast, or unknown destination traffic Layer 4 prioritisation: enables prioritisation based on TCP/UDP port numbers Management Choice of management interfaces: Web graphical user interface (GUI): HTML-based easy-to-use graphical interface allows configuration of the switch from any Web browser. Comm&-line interface (CLI): provides advanced configuration & diagnostics through a robust CLI. Simple Network Management Protocol (SNMPv 1/v 2c/v 3): allows a switch to be managed with a variety of third-party network management applications. Virtual stacking: provides single IP address management for up to 16 switches s Flow (RFC 3176): delivers wire-speed traffic accounting & monitoring configured by SNMP & CLI with three terminal encrypted receivers IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automates device discovery protocol for easy mapping by network management applications Logging: provides local & remote logging of events via SNMP (v 2c & v 3) & syslog; provides log throttling & log filtering to reduce the number of log events generated Connectivity IPv 6: IPv 6 host: allows the switch to be deployed & managed at the edge of an IPv 6 network. Dual stack (IPv 4/IPv 6): supports connectivity for both protocols; provides a transition mechanism from IPv 4 to IPv 6. MLD snooping: forwards IPv 6 multicast traffic to the appropriate interface; prevents IPv 6 multicast traffic from flooding the network. Auto-MDIX: adjusts automatically for straight-through or crossover cables on all ports Layer 2 switching VLANs: provides support for 512 VLANs & 4, 094 VLAN IDs 16K MAC address table: provides access to many Layer 2 devices GARP VLAN Registration Protocol: allows automatic learning & dynamic assignment of VLANs ...
