When a clear IP address is assigned to an interface, enable Internet Protocol (IP) on the serial port) ipx delay setting point count Ipx ipxwan starting IPXWAN protocol Ipx maximum-paths when forwarding packets set the number of equal paths used by Cisco IOS software Ipx network Enable Route Selection for Internet Packet Exchange (IPX) on a specific interface and select the encapsulation type (encapsulated by frame) ipx routing the routing protocol Ipx routing specified by IPX router start Ipx route select Ipx sap-interval set less frequent SAP on slow links (Business Advertising Protocol) update the Ipx type-20-input-checks restriction on the propagation of IPX20 packets. Accept Isdn spid1 specifies on the vro business that has been allocated by the ISDN service supplier for the B1 channel (SPID) on the vro, Isdn spid2 specifies the business profile number (SPID) allocated by the ISDN service supplier for the B2 channel) isdn switch-type specifies that the type of the switch in the central office area of the ISDN interface is Keeplive, which uses the serial line (Local Management Interface) encapsulated by frame relay) mechanism Lat open LAT connection Line determine a specific Line and start Line configure Line concol E. Set the Console port Line vty to allow remote console access.

Mstat traces the multicast address multiple times and then displays the statistics. source to target tracing resolution multicast address path Name-connection Name existing Network connection Ncia enable/disable NCIA server Network assign a NIC-based address to a vro directly connected to it the network is associated with the route selection process of an IGRP in IPX In router configuration mode, enable the enhanced IGRPNetwork on the Network to specify a Network address segment Network-number that is directly connected to the vro to specify a directly connected Network No shutdown open a closed interface Pad open an X.29 PAD connect Permit to a named ip acl and set the condition Ping. Send the ICMP response packet to another node on the network to check the accessibility and network connectivity of the host. Ping the basic connectivity of the network. send echo request, diagnose basic network connectivity Ppp start IETF Point-to-Point Protocol Ppp authentication Start Challenge Handshake authentication Protocol (CHAP) or password authentication protocol (PAP) or both start, in addition, it specifies the CHAP and PAP authentication sequence selected on the interface. When Ppp chap hostname is used for identity authentication, a batch of Ppp CHAP passwor vrouters that appear to be the same host are created. D. Set a password, this password is sent to the Host Command for authentication on the vro to limit the number of user names/passwords that enter the vro. Ppp pap sent-username enables remote PAP support for an interface, the sent-username and passwordProtocol are used to define an IP Route Selection protocol during the PAP verification of request packets at the same layer. This protocol can be RIP, the Internal Gateway selects the Protocol (IGRP) for routing, and opens the Shortest Path First (OSPF). It can also enhance the IGRPPwd display that the current device name Reload is disabled and the cold start is executed; restart the operating system Rlogin to open an active network connection. The Router uses the IP address routing protocol defined in the first item as the routing process. For example: router rip selects RIP as the routing protocol Router igrp to start an IGRP route selection process Router rip selects RIP as the routing selection protocol Rsh to execute a remote command Sdlc to send SDLC test frames Send message Service password-encryption on tty line encrypt password Setup run Setup command Show run system info Show access-lists Show all current ACL content Show buffers display cache statistics show cdp entry information Show information about adjacent devices listed in CDP table Show cdp interface Information Show CDP interface Information Show cdp neighbors display CDP search process results Show dialer display as DDR (digital data receiver) general diagnostic information of the configured serial interface Show flash display layout and content information of flash memory Show frame-relay LMIS display about local management interface (LMS) show frame-relay map: displays the current ing entry and information of the connection.
