Router Port

A router port is a port on the Ethernet switch that leads switch towards the Layer 3 multicast device.

In 1998, the IEEE with document 802.1w introduced an evolution of STP: the R

RSTP

apid Spanning Tree Protocol,

which provides for faster spanning tree convergence after a topology change. Standard IEEE 802.1D-2004 now

incorporates RSTP and obsoletes STP, while at the same time being backwards-compatible with STP.

SNMP

ronym for SSNMP is an ac imple Network Management Protocol. It is part of the Transmission Control

Protocol/Internet Protocol (TCP/IP) protocol for network management. SNMP allow diverse network objects to

STP

Spanning Tree Protocol is an OSI layer-2 protocol which ensures a loop free topology for any bridged LAN. The

original STP protocol is now obsoleted by RSTP.

Tag Priority

Tag Priority is a 3-bit field storing the priority level for the 802.1Q frame.

TCP

TCP is an acronym for Transmission Control Protocol. It is a communications protocol that uses the Internet

ble and in-order delivery of data from sender to receiver and distinguishes

data for multiple connections by concurrent applications (for example, Web server and e-mail server) running on

The applications on networked hosts can use TCP to create connections to one another. It is known as a

connection-oriented protocol, which means that a connection is established and maintained until such time as

the message or messages to be exchanged by the application programs at each end have been exchanged.

TCP is responsible for ensuring that a message is divided into the packets that IP manages and for reassembling
