Verify that CDP is enabled, update timer, hold timer and CDP version.ĭisplay all directly connected neighbor devices and confirm there is Layer 2 connectivity to each neighbor and the following neighbor details: The Protocol column is equivalent to Line Protocol (Layer 2) for show interfaces command.ĭisplay the operational status (up/up), IP address, configuration settings and errors for a specific switch or router interface. The Status column is equivalent to Interface (Layer 1) for show interfaces command. Summarizes the operational status (up/up) and IP address of all switch and router interfaces. Verify operational status (up/up), IP address and subnet mask of all network interfaces. switch# c? Global Commandsĭisplay the current running configuration script on any Cisco device.ĭisplay a variety of device information including the following: That helps list commands available that start with the same letters. The partial command level question ? provides a list of all commands that begin with the letters specified. Switch(config-if)# show interfaces ? Partial Commands It is a quick reference for correct configuration syntax and commands not supported with the current IOS version. In addition the question ? after any IOS command displays syntax options for that specific command. The command level ? provides a list of all commands for that subgroup such as show commands for instance. The List of commands available from each Cisco device mode is available with question mark ? from each top level mode prompt. The IOS commands are based on all topics from the published CCNA exam guidelines. They are all standard IOS commands used to configure, verify and troubleshoot network connectivity. The following is a list of the most common IOS commands associated with questions from the CCNA exam. One of the most powerful commands in IOS is show. Like any operating system, IOS includes a command language to enable equipment owners to retrieve information and change the device’s settings. Cisco routers/switch run an operating system, called IOS. If there is no match, # return a default value: '' intf_ip_addr = intf_obj. re_match_typed ( '^interface\s (\S. ?)$' ) # Search children of all interfaces for a regex match and return # the value matched in regex match group 1. find_objects ( '^interface' ): intf_name = intf_obj. from ciscoconfparse import CiscoConfParse parse = CiscoConfParse ( 'nf', syntax = 'ios' ) for intf_obj in parse. The next example will find the IP address assigned to interfaces. find_objects_w_child ( '^interface', '^\s shutdown' ): print ( "Shutdown: " intf_obj. The following code will parse a configuration stored in ‘nf’Īnd select interfaces that are shutdown.
