  • Page 141: Cli Command Modes

    CLI Command Modes Since the set of CLI commands is very large, the CLI is structured as a command-tree hierarchy, where related command sets are assigned to command modes for easier access. At each level, only the commands related to that level are available to the user and only those commands are shown in the context sensitive help for that level.
  • Page 142 The Privileged EXEC mode provides access to commands that can not be executed in the User EXEC mode and permits access to the switch Configuration mode. The Global Configuration mode manages switch configuration on a global level. For specific interface configurations, command modes exist at a sub- level.
  • Page 143 Global Configuration Mode Global Configuration commands apply to features that affect the system as a whole, rather than just a specific interface. The Privileged EXEC mode command configure is used to enter the Global Configuration mode. console(config)# Interface and Other Specific Configuration Modes Interface configuration modes are used to modify specific interface operations.

  • Page 886: Ip Ospf Network

    Default Configuration This command has no default configuration. Command Mode Interface Configuration (VLAN) mode. User Guidelines This command has no user guidelines. Example The following example disables OSPF MTU mismatch detection on VLAN interface 15. console(config-if-vlan15)#ip ospf mtu-ignore ip ospf network Use the ip ospf network command to configure OSPF to treat an interface as a point-to-point rather than broadcast interface.
  • Page 887: Ip Ospf Priority

    Usage Guidelines OSPF treats interfaces as broadcast interfaces by default. Loopback interfaces have a special loopback network type, which cannot be changed. When there are only two routers on the network, OSPF can operate more efficiently by treating the network as a point-to-point network. For point-to-point networks, OSPF does not elect a designated router or generate a network link state advertisement (LSA).
  • Page 888: Ip Ospf Retransmit-Interval

    User Guidelines A value of 1 is the highest router priority. A value of 0 indicates that the interface is not eligible to become the designated router on this network.

  • Page 962: Nsf Helper

    Command Mode Router OSPFv3 Configuration mode User Guidelines Graceful restart works in concert with nonstop forwarding to enable the hardware to continue forwarding IPv6 packets using OSPFv3 routes while a backup unit takes over management unit responsibility. When OSPF executes a graceful restart, it informs its neighbors that the OSPF control plane is restarting, but that it will be back shortly.
  • Page 963: Nsf Helper Strict-Lsa-Checking

    Command Mode Router OSPFv3 Configuration mode User Guidelines The grace LSA announcing the graceful restart includes a restart reason. Reasons 1 (software restart) and 2 (software reload/upgrade) are considered planned restarts. Reasons 0 (unknown) and 3 (switch to redundant control processor) are considered unplanned restarts.
  • Page 964: Nsf Restart-Interval

    User Guidelines The restarting router is unable to react to topology changes. In particular, the restarting router will not immediately update its forwarding table; therefore, a topology change may introduce forwarding loops or black holes that persist until the graceful restart completes. By exiting the graceful restart on a topology change, a router tries to eliminate the loops or black holes as quickly as possible by routing around the restarting router.
  • Page 965: Passive-Interface

    User Guidelines The grace period must be set long enough to allow the restarting router to reestablish all of its adjacencies and complete a full database exchange with each of those neighbors. Example – passive-interface Use the passive-interface command to set the interface or tunnel as passive. It overrides the global passive mode that is currently effective on the interface or tunnel.
  • Page 966: Passive-Interface Default

    passive-interface default The passive-interface default command enables the global passive mode by default for all interfaces. It overrides any interface level passive mode. Use the “no” form of this command to disable the global passive mode by default for all interfaces. Any interface previously configured to be passive reverts to non- passive mode.
