Assign IP address to both routers and turn them onĢ. We will configure the clock speed on the router that has the DCE side connected.ġ. The following lab uses a serial cable that will simulate a service provider. Smart-connector (Female type) that requires Serial Cables with the proper type of connector (Male Smart-Connector) and also with the DCE/DTE designation (more about DCE/DTE later) The following image shows a Serial Cable with Smart connectors at both ends, which must be used if both sides of the Link are implemented with these types of cards. Generally, the clock speed is configured according to the availability of the bandwidth speed that the service provider is offering. In the real world, the DCE side of the cable is configured by the service provider. We will set up a clock rate at 56000, which will provide a speed of 56 Kbps. #Cisco serial connector types license#You must also think that Apex offers all Plus license functionality. In this lab, we will configure a Serial Connection between the routers. Whether you choose the Plus or Apex plan, Cisco guarantees that both licenses eliminate the need to purchase per headend connections and dedicated license servers. ![]() Even on cisco routers, organizations prefer PPP protocol over HDLC protocol due to its advanced features and benefits. If we are configuring a new cisco router then by default the data link protocol would be HDLC however if we are configuring an old device then we should check the configuration and if there is a mismatch then we have to configure the same protocol on both routers.Īlthough HDLC works out of the box on all cisco routers however it is not widely used because of its proprietary nature and it does not provide much feature so PPP protocol is used by the most organization. If there will be a mismatch then a connection cannot be established and we will see the status of the interface as down under the data link. If we want to establish a successful connection with a router of other vendors then we must configure the same data link protocol on both routers. with the non-Cisco routers) because this protocol is solely a Cisco proprietary. A picture of the console cable is shown below. One end of the cable is RJ49 type and a DB9 to RJ45 converter is molded on the other end. Table C-18 AT3, AE3, MM3, and SMI3 Connector Types and Cables. A special type of cable, known as roll over cable is used to connect the Serial/COM port of the computer to the router or switch console port. However, this will not work with other brands’ routers (i.e. Table C-1 lists the signals and pinouts for the asynchronous serial console port, the RJ. If we have Cisco routers on both sides of the network then the default encapsulation known as HDLC will be used by the Cisco routers. One of the connections used for a leased line is the Serial Connection in Cisco-based networks. based on the bandwidth they offer to their client organizations. And accordingly, the service providers charge for this service i.e. Businesses have to pay for these leased lines according to the service availed. ![]() RS232 V.24 connector DB25 V.The Serial Connection is used to create a WAN connection with the help of a service provider who offers a dedicated leased line to its customers.īusiness organizations buy leased lines to establish a WAN connection to connect with different offices and business sites that could physically be thousands of miles apart. RJ-45 RS232 connector RJ45 RS232D connectors (same as telephone connectors)įig.4. Note: The RI pin (#1) sometimes can be used as DSR.įig.3. #Cisco serial connector types how to#We finalized by learning how to troubleshoot serial interfaces. We discussed the use of the DTE and DCE and then we looked at the default WAN encapsulation on CISCO routers which is HDLC. #Cisco serial connector types software#The IOS software looks for a valid configuration file store in NVRAM (startup-config). In this chapter, we have discussed serial interfaces in detail, we discussed how communication over serial links works as well as the types of serial links. It can be used only for nonsynchronous applications onlym because it does not have synchronous clocking signals. Cisco router looks for IOS by default in flash memory (EEPROM). Computer Com Port (RS-232/V.24 pin out on a DB-9)ĮIA-561 defined RS232 on RJ 45 (modular) connector. ![]()
