br> 39. On a 7500 series router the command format to configure serial interface is int s 1/0/0. First you specify interface that is S in this example then the slot that is 1, then the port adapter that is 0 and then the port that is 0. Where as in case of a Cisco 5500 switch, the command would be int s 1/0 where 1 is the slot and 0 is the port. 40. STP spanning tree protocol is used to prevent routing loops on a switch and STA is the algorithm created by STP. 41. What does the log parameter in the IPX access-list do. (Records the number of times that a packet matches the list). 42. To configure an interface for PPP encapsulation use command Router(config-if)# encapsulation ppp and to configure for PPP authentication use the command Router(config-if)# ppp authentication chap|pap. This is all I remember, but can give you some important information on Cisco IOS 11.2 commands. Steps of Data Encapsulation: 1.User information is converted to data 2.Data converted to segments 3.Segments converted to packets or datagrams 4.Packets and datagrams are converted to frames 5.Frames are converted to bits Frame Types: 802.3 – novell-ether – default 802.2 – sap Ethernet_II – arpa Ethernet_snap – snap Switching – examines MAC address. Store-and-Forward – copies entire frame into buffer, checks for CRC errors. Higher latency. Used by Catalyst 5000 switches Cut-Through – reads only the destination address into buffer, and forwards immediately. Low latency Virtual LAN's – have different ports on a switch be parts of different subnetworks. Some benefits: Simplify moves, adds, changes. Reduce administrative costs, better control of broadcasts, tighten security, and distribute load. Relocate server into secured locations. Cisco IOS (operating system) is stored in flash memory (EEPROM) IOS configuration is stored in NVRAM User Mode – ordinary tasks – checking status, etc. Need password depending on how you're entering (Virtual Terminal pw for telnet session, Auxiliary pw for aux port, Console pw for console port) conf t line vty 0 {line aux 0} {line con 0} login password let
