7.  RFC2674 for 802.1p 
8.  IEEE 802.1X MIB 
•  IEEE 802.3x flow control in full duplex mode 
•  IEEE 802.1p Priority Queues 
•  IEEE 802.3u 100BASE-TX compliant 
•  RS-232 DCE console port for Switch management  
•  Provides parallel LED display for port status such as link/act, speed, etc.
•  IEEE 802.3 10BASE-T compliant 
•  High performance switching engine performs forwarding and filtering at wire speed, maximum 14,881 packets/sec 
on each 10Mbps Ethernet port, maximum 148,810 packet/sec on 100Mbps Fast Ethernet port and 1,488,100 for each 
Gigabit port 
•  Full and half-duplex for both 10Mbps and 100Mbps connections. Full duplex allows the switch port to 
simultaneously transmit and receive data. It only works with connections to full-duplex-capable end stations and 
switches. Connections to a hub must take place at half-duplex 
•  Support Broadcast/Multicast storm control 
•  Non-blocking store and forward switching scheme capability to support rate adaptation and protocol conversion 
•  Supports by-port Egress/Ingress rate control 
•  Efficient self-learning and address recognition mechanism enables forwarding rate at wire speed
