Angle brackets (< >) are not always used to indicate that a LINE is an argument. (carriage return) Indicates the end of the list of — available keywords and arguments, and also indicates when keywords and arguments are optional.
Using the Command-Line Interface in Cisco IOS Software Using the CLI Note Both password commands have numeric keywords that are single integer values. If you choose a number for the first character of your password followed by a space, the system will read the number as if it were the numeric keyword and not as part of your password. When both passwords are set, the enable secret password takes precedence over the enable password.
Using the Command-Line Interface in Cisco IOS Software Using the CLI Abbreviating Commands Typing a complete command name is not always required for the command to execute. The Cisco IOS CLI recognizes an abbreviated command when the abbreviation contains enough characters to uniquely identify the command. For example, the show version command can be abbreviated as sh ver. It cannot be abbreviated as s ver because s could mean show, set, or systat.
Using the Command-Line Interface in Cisco IOS Software Using the CLI Configuration commands may also have a default form, which returns the command settings to their default values. For commands that are disabled by default, using the default form has the same effect as using the no form of the command. For commands that are enabled by default and have default settings, the default form enables the command and returns the settings to their default values.
Using the Command-Line Interface in Cisco IOS Software Saving Changes to a Configuration Understanding CLI Error Messages You may encounter some error messages while using the CLI.

IP Switching Commands ip cache-invalidate-delay ip cache-invalidate-delay To control the invalidation rate of the IP route cache, use the ip cache-invalidate-delay command in global configuration mode. To allow the IP route cache to be immediately invalidated, use the no form of this command. ip cache-invalidate-delay [minimum maximum quiet threshold] no ip cache-invalidate-delay Syntax Description minimum (Optional) Minimum time (in seconds) between invalidation request and actual invalidation.
IP Switching Commands ip cache-invalidate-delay This command controls how the route cache is flushed. The intent is to delay invalidation of the cache until after routing has settled down. Because route table changes tend to be clustered in a short period of time, and the cache may be flushed repeatedly, a high CPU load might be placed on the router. When this feature is enabled, and the system requests that the route cache be flushed, the request is held for at least minimum seconds.
IP Switching Commands ip cef ip cef To enable Cisco Express Forwarding (CEF) on the route processor card, use the ip cef command in global configuration mode. To disable CEF, use the no form of this command. ip cef [distributed] no ip cef [distributed] Syntax Description distributed Defaults CEF is disabled by default, excluding these platforms: (Optional) Enables distributed CEF (dCEF) operation. Distributes CEF information to line cards. Line cards perform express forwarding.
IP Switching Commands ip cef If you enable CEF and then create an access list that uses the log keyword, the packets that match the access list are not CEF switched. They are fast switched. Logging disables CEF.
IP Switching Commands ip cef accounting ip cef accounting To enable Cisco Express Forwarding (CEF) network accounting, use the ip cef accounting command in global configuration mode or interface configuration mode. To disable network accounting of CEF, use the no form of this command.
IP Switching Commands ip cef accounting For prefixes with directly connected next hops, the non-recursive keyword enables the collection of packets and bytes to be express forwarded through a prefix. This keyword is optional when this command is used in global configuration mode. This command in interface configuration mode must be used in conjunction with the global configuration command.
IP Switching Commands ip cef linecard ipc memory ip cef linecard ipc memory To configure the line card memory pool for the Cisco Express Forwarding (CEF) queuing messages, use the ip cef linecard ipc memory command in global configuration mode. To return to the default Inter-process Communications (IPC) memory allocation, use the no form of this command. ip cef linecard ipc memory kbps no ip cef linecard ipc memory kbps Syntax Description kbps Defaults Default IPC memory allocation is 25 messages.
IP Switching Commands ip cef load-sharing algorithm ip cef load-sharing algorithm To select a Cisco Express Forwarding (CEF) load-balancing algorithm, use the ip cef load-sharing algorithm command in global configuration mode. To return to the default universal load-balancing algorithm, use the no form of this command.
IP Switching Commands ip cef load-sharing algorithm Usage Guidelines The original CEF load-balancing algorithm produced distortions in load sharing across multiple routers because of the use of the same algorithm on every router. When the load-balancing algorithm is set to universal mode, each router on the network can make a different load sharing decision for each source-destination address pair, and that resolves load-balancing distortions.
IP Switching Commands ip cef table adjacency-prefix ip cef table adjacency-prefix To modify how Cisco Express Forwarding (CEF) adjacency prefixes are managed, use the ip cef table adjacency-prefix command in global configuration mode. To disable CEF adjacency prefix management, use the no form of this command.
IP Switching Commands ip cef table adjacency-prefix validate When you add a /31 netmask route, the new netmask does not overwrite an existing /32 CEF entry. This problem is resolved by configuring the validate keyword to periodically validate prefixes derived from adjacencies in the FIB against prefixes originating from the RIB.
IP Switching Commands ip cef table adjacency-prefix ip cef table adjacency-prefix The override keyword for the ip cef table adjacency-prefix command is no longer documented as a separate command. The information for using the override keyword for the ip cef table adjacency-prefix command has been incorporated into the ip cef table adjacency-prefix command documentation. See the ip cef table adjacency-prefix command documentation for more information.
IP Switching Commands ip cef table consistency-check ip cef table consistency-check To enable consistency checker types and parameters for Cisco Express Forwarding (CEF) tables, use the ip cef table consistency-check command in global configuration mode. To disable consistency checkers, use the no form of this command.
IP Switching Commands ip cef table consistency-check Usage Guidelines Release Modification 12.2(14)SX Support for this command was implemented on the Supervisor Engine 720. 12.2(17d)SXB Support for this command on the Supervisor Engine 2 was integrated into Release 12.2(17d)SXB. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA.
IP Switching Commands ip cef table consistency-check Related Commands, Command Description clear ip cef inconsistency Clears CEF inconsistency statistics and records found by the CEF consistency checkers. debug ip cef Displays various CEF table query and check events. show ip cef inconsistency Displays CEF IP prefix inconsistencies.
IP Switching Commands ip cef table event-log ip cef table event-log To control Cisco Express Forwarding (CEF) table event-log characteristics, use the ip cef table event-log command in global configuration mode.
IP Switching Commands ip cef table event-log Examples The following example shows how to set the CEF table event log size to 5000 entries: Router(config)# ip cef table event-log size 5000 Related Commands Command Description clear ip cef event-log Clears the CEF event-log buffer. ip cef table consistency-check Enables CEF table consistency checker types and parameters. show ip cef events Displays all recorded CEF FIB and adjacency events.
IP Switching Commands ip cef table resolution-timer ip cef table resolution-timer To change the Cisco Express Forwarding (CEF) background resolution timer, use the ip cef table resolution-timer command in global configuration mode. ip cef table resolution-timer seconds no ip cef table resolution-timer seconds Syntax Description seconds Defaults The default configuration value is 0 seconds for automatic exponential backoff.
IP Switching Commands ip load-sharing ip load-sharing To enable load balancing for Cisco Express Forwarding (CEF), use the ip load-sharing command in interface configuration mode. ip load-sharing [per-packet] [per-destination] Syntax Description per-packet (Optional) Enables per-packet load balancing on the interface. per-destination (Optional) Enables per-destination load balancing on the interface. Defaults Per-destination load balancing is enabled by default when you enable CEF.
IP Switching Commands ip load-sharing Examples The following example shows how to enable per-packet load balancing: Router(config)# interface E0 Router(config-if)# ip load-sharing per-packet The following example shows how to enable per-destination load balancing: Router(config)# interface E0 Router(config-if)# ip load-sharing per-destination Related Commands Command Description ip cef Enables CEF on the RP card.
IP Switching Commands ip route-cache ip route-cache To control the use of switching methods for forwarding IP packets, use the ip route-cache command in interface configuration mode. To disable any of these switching methods, use the no form of this command. ip route-cache [cef | distributed | flow | policy | same-interface] no ip route-cache [cef | distributed | flow | policy | same-interface] Syntax Description Defaults cef (Optional) Enables Cisco Express Forwarding operation on an interface.
IP Switching Commands ip route-cache Usage Guidelines Note Release Modification 11.1CC cef keyword support was added for multiple platforms. 12.0 The policy keyword was added. 12.2(25)S This command was integrated into Cisco IOS Release 12.2(25)S. The ip route-cache flow command is automatically remapped to the ip flow ingress command. 12.2(28)SB This command was integrated into Cisco IOS Release 12.2(28)SB. This command is not supported on the Cisco 10000 series router. 12.
IP Switching Commands ip route-cache On Cisco routers with Route/Switch Processor (RSP) and VIP controllers, the VIP hardware can be configured to switch packets received by the VIP with no per-packet intervention on the part of the RSP. When VIP distributed switching is enabled, the input VIP interface tries to switch IP packets instead of forwarding them to the RSP for switching. Distributed switching helps decrease the demand on the RSP.
IP Switching Commands ip route-cache Examples Configuring Fast Switching and Disabling Cisco Express Forwarding Switching The following example shows how to enable fast switching and disable Cisco Express Forwarding switching: Router(config)# interface ethernet 0/0/0 Router(config-if)# ip route-cache The following example shows that fast switching is enabled: Router# show ip interface fastEthernet 0/0/0 FastEthernet0/0/0 is up, line protocol is up Internet address is 10.1.1.
IP Switching Commands ip route-cache The following example shows the configuration information for interface fastethernet 0/0/0: Router# show running-config . . ! interface FastEthernet0/0/0 ip address 10.1.1.254 255.255.255.
IP Switching Commands ip route-cache MTU is 1500 bytes Helper address is not set Directed broadcast forwarding is disabled Multicast reserved groups joined: 224.0.0.
IP Switching Commands ip route-cache Directed broadcast forwarding is disabled Multicast reserved groups joined: 224.0.0.
IP Switching Commands ip route-cache Transmit limit accumulator 0x48001A02 (0x48001A02) IP MTU 1500 Configuring Fast Switching for PBR The following example shows how to configure a simple policy-based routing scheme and to enable FSPBR: Router(config)# access-list 1 permit 10.1.1.0 0.0.0.255 Router(config)# route-map mypbrtag permit 10 Router(config-route-map)# match ip address 1 Router(config-route-map)# set ip next-hop 10.1.1.
IP Switching Commands ip route-cache Command Description exit Leaves aggregation cache mode. ip cef Enables Cisco Express Forwarding on the RP card. ip cef distributed Enables distributed Cisco Express Forwarding operation. ip flow ingress Configures NetFlow on a subinterface. show ip interface Displays the usability status of interfaces configured for IP. show cef interface Displays detailed Cisco Express Forwarding information for interfaces.
IP Switching Commands ip route-cache policy ip route-cache policy The policy keyword for the ip route-cache command is no longer documented as a separate command. The information for using the policy keyword for the ip route-cache command has been incorporated into the ip route-cache command documentation. See the ip route-cache command documentation for more information.
IP Switching Commands ip verify unicast notification threshold ip verify unicast notification threshold To configure the threshold value used to determine whether to send a unicast reverse path forwarding (URPF) drop rate notification, use the ip verify unicast notification threshold command in interface configuration mode. To set the notification threshold back to the default value, use the no form of this command.
IP Switching Commands ip verify unicast reverse-path ip verify unicast reverse-path Note This command was replaced by the ip verify unicast source reachable-via command effective with Cisco IOS Release 12.0(15)S.
IP Switching Commands ip verify unicast reverse-path Usage Guidelines Use the ip verify unicast reverse-path interface command to mitigate problems caused by malformed or forged (spoofed) IP source addresses that are received by a router. Malformed or forged source addresses can indicate denial of service (DoS) attacks on the basis of source IP address spoofing. When Unicast RPF is enabled on an interface, the router examines all packets that are received on that interface.
IP Switching Commands ip verify unicast reverse-path For example, routers at the edge of the network of an ISP are more likely to have symmetrical reverse paths than routers that are in the core of the ISP network. Routers that are in the core of the ISP network have no guarantee that the best forwarding path out of the router will be the path selected for packets returning to the router.

IP Switching Commands ip verify unicast source reachable-via Unicast RPF checks to determine whether any packet that is received at a router interface arrives on one of the best return paths to the source of the packet. If a reverse path for the packet is not found, Unicast RPF can drop or forward the packet, depending on whether an ACL is specified in the Unicast RPF command.
IP Switching Commands ip verify unicast source reachable-via the network of an ISP are likely to have symmetrical reverse paths. Unicast RPF strict mode may still be applicable in certain multihomed situations, provided that optional Border Gateway Protocol (BGP) attributes, such as weight and local preference, are used to achieve symmetric routing. Note With Unicast RPF, all equal-cost “best” return paths are considered valid.
