    Command Groups Introduction The Command Language Interface (CLI) is a network management application operated through an ASCII terminal without the use of a Graphic User Interface (GUI) driven software application. By directly entering commands, the user has greater configuration flexibility. The CLI is a basic command-line interpreter similar to the UNIX C shell.

  • Page 49: Using The Cli

    Using the CLI This chapter describes how to start using the CLI and describes implemented command editing features to assist in using the CLI. CLI Command Modes Introduction To assist in configuring devices, the CLI command-line interface is divided into different command modes.
  • Page 50 When starting a session, the initial mode is the User EXEC mode. Only a limited subset of commands are available in this mode. This level is reserved for tasks that do not change the configuration. To enter the next level, the Privileged EXEC mode, a password is required. The Privileged EXEC mode provides access to commands that are restricted on the User EXEC mode level and permits access to the device Configuration mode.
  • Page 51 To return from the Privileged EXEC mode to the User EXEC mode, use the disable command. The following example illustrates how to access the Privileged EXEC mode and return to the User EXEC mode: Console>enable Enter Password: ****** Console # Console # disable Console>...
  • Page 52 Interface Configuration Mode and Specific Configuration Modes Interface configuration modes are used to modify specific interface operations. The following are the Interface Configuration modes: • Line Interface—Contains commands to configure the management connections. These include commands such as line speed, timeout settings, etc. The Global Configuration mode command line is used to enter the line configuration command mode.
  • Page 53: Starting The Cli

    • Key-Chain—Identifies a group of keys. The Global Configuration mode command key-chain is used to enter the key-chain configuration mode. • Global Configuration mode command interface ip is used to enter the Interface IP Configuration mode. Starting the CLI The switch can be managed over a direct connection to the switch console port, or via a Telnet connection.
  • Page 54 To enter commands that require parameters, enter the required parameters after the command keyword. For example, to set a password for the administrator, enter: Console(config)# username admin password smith When working with the CLI, the command options are not displayed. The command is not selected by a menu but is manually entered.
  • Page 55 Negating the Effect of Commands For many configuration commands, the prefix keyword no can be entered to cancel the effect of a command or reset the configuration to the default value. This guide describes the negation effect for all applicable commands. Command Completion If a command is entered and it is not complete, if the command is invalid, or if some parameters of the command are invalid or missing, the appropriate error message is displayed.
  • Page 56 CLI Command Conventions When entering commands there are certain command entry standards which apply to all commands. The following table describes the command conventions. Convention Description In a command line, square brackets indicates an optional entry. In a command line, curly brackets indicates a selection of compulsory parameters separated by the \ character.

  • Page 82: Deny (Mac)

    User Guidelines When an access control entry (ACE) is added to an access control list, an implied deny-any- any condition exists at the end of the list. If there are no matches, the packets are denied. However, before the first ACE is added, the list permits all packets. If vlan id is used as a classifier element then it cannot connect a policy map to a VLAN interface.
  • Page 83: Service-Acl

Syntax router ospf enable no router ospf enable Default Configuration The OSPF routing process is disabled.
  • Page 234: Router Ospf Redistribute Rip

    User Guidelines Auto-creation of OSPF areas is supported, so an OSPF area does not have to be defined before assigning it to an interface. To manually define an OSPF area, use the router ospf area command. If the auto-creation option is used, the area definition does not appear in the running configuration file.
  • Page 235: Router Ospf Redistribute Static

    User Guidelines If your network contains other routers that do not run OSPF, but do run RIP routing protocols, the OSPF process can incorporate those routes learned via RIP. When redistribution is enabled, the router becomes an “AS Boundary Router” (ASBR). OSPF is more robust and converges more rapidly than RIP.

Console (config)# router ospf area 1.1.1.1 virtual-link 1.1.1.1 hello-interval The hello-interval ospf virtual link interface configuration command specifies the interval between hello packets that the software sends on the OSPF virtual link interface.
  • Page 238: Dead-Interval

    dead-interval The dead-interval ospf virtual link interface configuration command sets the interval at which hello packets must not be seen before its neighbors declare the router down. To return to the default time, use the no form of this command. Syntax dead-interval seconds no dead-interval...
  • Page 239: Transmit-Delay

    Default Configuration The default value is 5 seconds. Command Mode OSPF virtual link configuration User Guidelines When a router sends an LSA to its neighbor, it keeps the LSA until it receives back the acknowledgment message. If the router receives no acknowledgment, it resends the LSA. The setting of this parameter should be conservative to prevent unnecessary retransmissions.
  • Page 240: Authentication

    If the delay is not added before transmission over a link, the time in which the LSA propagates over the link is not considered. This setting has more significance on very low- speed links. Example The following example sets the estimated time required to send a link-state update packet on the OSPF virtual link interface to 10 seconds.
  • Page 241: Router Ospf Router-Id

    router ospf router-id The router ospf router-id global configuration command configures an OSPF router ID. To return to default, use the no form of this command. Syntax router ospf router-id ip-address no router ospf router-id • ip-address—Specifies the OSPF router ID as an IP address. Default Configuration The default is the first interface IP address.
  • Page 242: Router Ospf Area Default-Cost

    User Guidelines The router ospf area stub command must be configured on all routers and access servers in the stub area. Use the area router configuration command with the default-cost option to specify the default internal router cost sent into a stub area by an ABR. There are two stub area router configuration commands: the stub and default-cost options of the area router configuration command.
  • Page 243: Ospf

    A default cost can be defined only for a stub area. To define a stub area, use the ospf area stub command. Example The following example specifies a cost of 10000 for the default summary route sent into a stub area number 192.168.3.1.
  • Page 244: Ospf Enable

    Example The following example enables OSPF on IP interface 1.100.100.100. Console(config)# interface ip 1.100.100.100 Console(config-ip)# ospf ospf enable The ospf enable interface configuration command activates OSPF on an interface. To deactivate OSPF on an interface, use the no form of this command. Syntax ospf enable no ospf enable...
  • Page 245: Ospf Cost

    Default Configuration The default is the first area (backbone area - 0.0.0.0). Command Mode IP Interface Configuration mode User Guidelines An OSPF area must be defined before it can be assigned to an interface. To define an OSPF area, use the router ospf area command. OSPF area auto-creation is supported, so an OSPF area does not have to be defined before assigning it to an interface.

    Default Configuration The default IP Interface dead-interval time is 40 seconds. Command Mode IP Interface Configuration User Guidelines The interval is advertised in router hello packets. This value must be the same for all routers and access servers on a specific network. Example The following example defines the OSPF dead-interval time of 100 seconds on interface 1.100.100.100.
  • Page 249: Ospf Transmit-Delay

    Example The following example specifies 60 seconds between link-state advertisement (LSA) retransmissions for IP interface 1.100.100.100 adjacencies.
