DSCP uses a six-bit tag to provide for up to 64 different forwarding
behaviors. Based on network policies, different kinds of traffic can be
marked for different kinds of forwarding. The DSCP bits are mapped to
the Class of Service categories, and then into the output queues.
A system used for translating host names for network nodes into IP
addresses.
Provides a framework for passing configuration information to hosts
on a TCP/IP network. DHCP is based on the Bootstrap Protocol
(BOOTP), adding the capability of automatic allocation of reusable
network addresses and additional configuration options.
EAPOl is a client authentication protocol used by this switch to verify
the network access rights for any device that is plugged into the
switch. A user name and password is requested by the switch, and
then passed to an authentication server (e.g., RADIUS) for verification.
EAPOl is implemented as part of the IEEE 802.1X Port Authentication
standard.
gMRP allows network devices to register end stations with multicast
groups. gMRP requires that any participating network devices or end
stations comply with the IEEE 802.1p standard.
Specifies a general method for the operation of MAC bridges,
includingthe Spanning Tree Protocol.
VlAn Tagging—Defines Ethernet frame tags which carry VlAn
information. It allows switches to assign end stations to different
virtual lAns, and defines a standard way for VlAns to communicate
across switched networks.
An IEEE standard for providing quality of service (QoS) in Ethernet
networks. The standard uses packet tags that define up to eight traffic
classes and allows switches to transmit packets based on the tagged
priority value.
An IEEE standard for the Multiple Spanning Tree Protocol (MSTP) which
provides independent spanning trees for VlAn groups.
