Router 10r2 Lab 1.2
A. The Interfaces that can be classifies as serial interfaces in Router 10R2 are as Follows a. Serial 1/0 b. Serial 1/1 c. Serial 1/2
B. The network end of the V.35 adapter cable provides a standard 34-pin Winchester- type connector. V.35 cables are available with a standard V.35 plug or receptacle in either DTE or DCE mode. V.35 Adapter Cable Connectors, Network End Yes by visual inspection of a v.35 cable with a Winchester connector, we can tell that the Male cable connects to a DTE and the Female cable connects to a DCE. Here the cables with pins is referred as male and cable without pins is referred as Female C. High-Speed Serial Interface (HSSI) is a short-distance communications interface that …show more content…
Standard protocol is not router specific. It also gives some authentication at different layer. HDLC (High-Level Data Link Control) does not support any kind of authentication. It is personalized, router-specific protocol. It cannot be used toconnect routers of different vendors.So if traffic analyzer may not recognize Cisco’s HDLC than it might not be compatible with this protocol.
2. The Supervisory frame(S-frame) and Unnumbered (U-frame) frame are the two frames of HDLC Protocol
Supervisory frameis used for flow and error control. Contain send / receive sequence numbers
Unnumbered frameis used for various rare purpose that includes link management (Link setup and disconnection). Some U-frame contains an information field. Such a frames do not contain in Acknowledgement information(No Sequence no.s).
3. Packet format of PPP.
(http://www.tcpipguide.com/free/t_PPPGeneralFrameFormat.htm)
Description:
Flag: Indicates the start of a PPP frame. Always has the value “01111110” binary (0x7E hexadecimal, or 126 decimal).
Address: In HDLC this is the address of the destination of the frame. But in PPP we are dealing with a direct link between two devices, so this field has no
