10BASE-T
IEEE 802.3 specification for 10 Mbps Ethernet
over two pairs of Category 3, 4, or 5 UTP cable.
100BASE-FX
IEEE 802.3u specification for 100 Mbps Fast
Ethernet over two strands of 50/125 or 62.5/
125 micron core fiber cable.
100BASE-TX
IEEE 802.3u specification for 100 Mbps Fast
Ethernet over two pairs of Category 5 UTP
cable.
1000BASE-LH
Gigabit Ethernet over two strands of 9/125
micron core fiber cable.
1000BASE-LX
IEEE 802.3z specification for Gigabit Ethernet
over two strands of 9/125 micron core fiber
cable.
1000BASE-SX
IEEE 802.3z specification for Gigabit Ethernet
over two strands of 50/125 or 62.5/125 micron
core fiber cable.
1000BASE-T
IEEE 802.3ab specification for Gigabit
Ethernet over four pairs of Category 5, 5e,
or 6 100-ohm UTP cable.
1000BASE-X
IEEE 802.3 shorthand term for any 1000 Mbps
Gigabit Ethernet based on 8B/10B signaling.
Access Control List (ACL)
ACLs can limit network traffic and restrict
access to certain users or devices by checking
each packet for certain IP or MAC (Layer 2)
information.
Address Resolution Protocol (ARP)
ARP converts between IP addresses and MAC
(hardware) addresses. ARP is used to locate
the MAC address corresponding to a given IP
address. This allows the switch to use IP
addresses for routing decisions and the
corresponding MAC addresses to forward
packets from one hop to the next.
Auto-negotiation
Signalling method allowing each node to select
its optimum operational mode (for example,
10, 100, or 100 Mbps and half or full duplex)
based on the capabilities of the node to which
it is connected.
