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.
Address Resolution Protocol (ARP)
ARP converts between IP addresses and MAC (i.e., 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.
Boot Protocol (BOOTP)
BOOTP is
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)
provides quality of service on large networks by employing a
DiffServ
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
used to provide bootup information for network devices,
