increase the link speed beyond the limits of any one single cable or port, and to increase the redundancy for
higher availability.
COS:
Class of Service 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.
SNMP:
Simple Network Management Protocol. The application protocol in the Internet suite of protocols which
offers network management services.
QOS:
Quality of Service. QoS refers to the capability of a network to provide better service to selected traffic flows
using features such as data prioritization, queuing, congestion avoidance and traffic shaping. These features
effectively provide preferential treatment to specific flows either by raising the priority of one flow or limiting the
priority of another flow.
DHCP:
Dynamic Host Control Protocol. 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.
DHCP OPTION 82:
A relay option for sending information about the requesting client (or an intermediate relay
agent) in the DHCP request packets forwarded by the switch and in reply packets sent back from the DHCP server.
This
information can be used by DHCP servers to assign fixed IP addresses, or set other services or policies for clients.
