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 (i.e., Layer 2)
information.
Boot Protocol
(BOOTP)
BOOTP is
used to provide bootup information for network devices,
including IP address information, the address of the TFTP server that
contains the devices system files, and the name of the boot file.
Class of Service
(CoS)
CoS is supported by prioritizing packets based on the required level of
service, and then placing them in the appropriate output queue. Data is
transmitted from the queues using weighted round-robin service to
enforce priority service and prevent blockage of lower-level queues.
Priority may be set according to the port default, the packet’s priority bit
(in the VLAN tag), TCP/UDP port number, IP Precedence bit, or DSCP
priority bit.
Differentiated Services
(DiffServ)
DiffServ
provides quality of service on large networks by employing a
well-defined set of building blocks from which a variety of aggregate
forwarding behaviors may be built. Each packet carries information (DS
byte) used by each hop to give it a particular forwarding treatment, or
per-hop behavior, at each network node.
DiffServ
allocates different levels
of service to users on the network with mechanisms such as traffic meters,
shapers/droppers, packet markers at the boundaries of the network.
Differentiated Services Code Point Service
(DSCP)
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
