Simple Network Time Protocol support
MAC Notification support
Asymmetric VLAN support
System and Port Utilization support
System Log Support
High performance switching engine performs forwarding and filtering at full wire speed, maximum 14, 881
packets/sec on each 10Mbps Ethernet port, and maximum 148,810 packet/sec on 100Mbps Fast Ethernet 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 storm filtering
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
Support port-based enable and disable
Address table: Supports up to 8K MAC addresses per device
Supports a packet buffer of up to 3 Mbits
Supports Port-based VLAN Groups
Port Trunking with flexible load distribution and fail-over function
IGMP Snooping support
SNMP support
Secure Sockets Layer (SSL) and Secure Shell (SSH) support
Port Mirroring support
MIB support for:
RFC1213 MIB II
RFC1493 Bridge
RFC1757 RMON
RFC1643 Ether-like MIB
RFC2233 Interface MIB
Private MIB
RFC2674 for 802.1p
IEEE 802.1x MIB
RS-232 DCE console port for Switch management
Provides parallel LED display for port status such as link/act, speed, etc.
Ports
Forty-eight (48) high-performance (MDI-X/MDI-II) ports for connecting to end stations, servers, hubs and other
networking devices.
All UTP ports can auto-negotiate between 10Mbps and 100Mbps, half-duplex and full duplex, and feature flow
control.
