High-performance throughput on each port at speeds up to 100 Mbps
Source and destination Media Access Control (MAC) address filtering
RMON EtherStats packet buffering
802.3 Ethernet standard compliant
4-port PICs support MTUs up to 9192 bytes; 12-port PICs support MTUs up to 1532 bytes; 48-port
PICs support MTUs up to 1532 bytes
4-port PICs support 1,024 802.1q VLANs per port; 12-port PICs support 16 802.1q VLANs per
port; 48-port PICs support 16 802.1q VLANs per port
Autosensing full-duplex and half-duplex modes
Virtual Router Redundancy Protocol (VRRP)
802.1q virtual LANs (VLANs)
Circuit cross-connect (CCC) VLAN
4-port PIC:
Connector: Two-pair, Category 5 unshielded twisted-pair connectivity through an RJ-45
connector
Pinout: MDI noncrossover
12-port PIC:
Connector: One very high density connector interface (VHDCI)-to-RJ-21 cable that connects
to an RJ-45 patch panel
48-port PIC:
VHDCI-to-RJ-21 cables that connect to an RJ-45 patch panel
Four VHDCI connectors that each service 12 10/100 ports
NOTE: Each of the four connectors on a 48-port Fast Ethernet PIC can support a maximum of
approximately 800 Mbps. However, this constitutes oversubscription. Use this PIC only in
environments that can support this level of oversubscription.
