Interswitch Link. A proprietary Cisco protocol for interconnecting
multiple switches and maintaining virtual LAN (VLAN) information as
traffic travels between switches. Working in a way similar to VLAN
trunking, described in the IEEE 802.1Q standard, ISL provides VLAN
capabilities while maintaining full wire-speed performance on Ethernet
links in full-duplex or half-duplex mode. ISL operates in a point-to-point
environment and supports up to 1000 VLANs.
International Organization for Standardization. An international
organization of national standards bodies from many countries. ISO has
defined a number of computer standards, including the Open Systems
Interconnection (OSI) standardized architecture for network design.
See initialization vector (IV).
In an Ethernet network, a frame whose data field exceeds 1500 bytes.
See WLAN.
Lightweight Directory Access Protocol. A protocol defined in RFC 1777
for management and browser applications that require simple
read-write access to an X.500 directory without incurring the resource
requirements of Directory Access Protocol (DAP). Protocol elements are
carried directly over TCP or other transport, bypassing much of the
session and presentation overhead. Many protocol data elements are
encoded as ordinary strings, and all protocol elements are encoded
with lightweight basic encoding rules (BER).
