Frame Relay Virtual Circuits (VCs) – Exclusiv Explanation

We have already discussed Frame Relay in the previous lessons. What is Frame Relay? Exclusive Introduction that it provides connection-oriented data link layer communication using a Frame Relay virtual circuit. Frame Relay Virtual Circuits (VCs) are a logical connection between two data terminal equipment (DTE) devices across a Frame Relay packet-switched network (PSN). The circuits...

How to Configure Challenge Handshake Authentication Protocol (CHAP)

Challenge Handshake Authentication Protocol (CHAP) periodically checks the character of the far off hub utilizing a three-way handshake. The hostname on one switch must match the username the other switch has designed. The passwords should likewise coordinate. The password value is variable and changes unpredictably while the link exists. When the PPP link establishment phase...

NCP Explained

When a PPP link has been initiated, the LCP passes control to the appropriate Network Control Protocol (NCP). NCP is a set of protocols that form part of PPP. PPP is a data link layer protocol that can transmit multiprotocol data between two point-to-point.  PPP’s modular model allows LCP to set up the link and...
