What is the difference between PPP and HDLC?
Differences between HDLC and PPP are(1) HDLC is cisco proprietary while PPP is an open standard.(2) HDLC does not provide authentication while PPP provides authentication like PAP and CHAP.(3) HDLC does not support compression while PPP support compression.(4) HDLC supports synchronous networks only while PPP supports both synchronous and asynchronous networks.
What major benefit does cisco hdlc provide that iso standard hdlc lacks?
multiprotocol support
What ppp protocol provides dynamic address authentication?
HDLC
What is the default encapsulation for serial interfaces on Cisco routers?
HDLC
Which encapsulation protocol when deployed on a Cisco router over a serial interface is only compatible with another Cisco router?
HDLC
What is the default WAN protocol for Cisco serial links?
HDLC
What is the default encapsulation type on a synchronous serial interface?
HDLC
What is bit stuffing in HDLC?
Bit stuffing is the insertion of non information bits into the data bits.In high level data link control protocol(HDLC),it provides a means of synchronization.
What is the frame format HDLC in networking?
HDLC - High level data link control used in conjunction with Networking protocols like PPP (point-to-point) protocol. According to RFC 1662, PPP uses HDLC like frame by providing address and control fields. For PPP these fields are constants 0xFF and 0x03.
What are the benefits of using the PPP encapsulation type instead of the default HDLC?
HDLC (High-Level Data Link Control) is a bit-oriented synchronous data link layer protocol cHDLC (Cisco HDLC) was created by cisco to address the HDLC protocol's inability to provide multi-protocol support. Thus, cHDLC frames contain a field for identifying the network protocol being encapsulated. Ethernet networks are packet based and have no concept of a connection or circuit and also lack basic security features By using PPPoE (encapsulation), users can "dial" from one machine to another over an Ethernet network, establish a point to point connection between them and then securely transport data packets over the connection. Answer: security
What is full form of HDLC in networking?
High level data link control
Which additional functionality is available on an interface when the encapsulation is changed from HDLC to PPP?
Authentication
