Port-based VLAN
A type of virtual LAN setup wherein each physi-
cal switch port has an access list specifying
membership in a set of VLANs.
Network VirusWall Enforcer 2500 supports
port-based VLAN through Port Grouping Opera-
tion Mode.
PPPoE
Short for Point-to-Point Protocol over Ethernet.
PPPoE relies on two widely accepted standards:
PPP and Ethernet. PPPoE is a specification for
connecting the users on an Ethernet to the Inter-
net through a common broadband medium,
such as a single DSL line, wireless device, or
cable modem. All the users over the Ethernet
share a common connection, so the Ethernet
principles supporting multiple users in a LAN
combine with the principles of PPP, which apply
to serial connections.
PPTP
Short for Point-to-Point Tunneling Protocol, a
new technology for creating Virtual Private Net-
works (VPNs), developed jointly by Microsoft
Corporation, U.S. Robotics, and several remote
access vendor companies, known collectively as
the PPTP Forum.
