CH A P T E R 1 Using the Command-Line Interface The Cisco Metro Ethernet (ME)3600 and 3800 Series switch is supported by Cisco IOS software. This chapter describes how to use the switch command-line interface (CLI) to configure software features. For a complete description command descriptions, see these sections: • For the configuration and monitoring commands that support these features, see Chapter 2, “Cisco ME 3800X and ME 3600X Switch Cisco IOS Commands.
Chapter 1 Using the Command-Line Interface CLI Command Modes Table 1-1 lists the main command modes, how to access each mode, the prompt you see in that mode, and how to exit that mode. The prompts listed use the default name Switch. Table 1-1 Command Modes Summary Command Mode Access Method Prompt Exit or Access Next Mode User EXEC This is the first level of access. Switch> Enter the logout command.
Chapter 1 Using the Command-Line Interface CLI Command Modes Privileged EXEC Mode Because many of the privileged commands configure operating parameters, privileged access should be password-protected to prevent unauthorized use. The privileged command set includes those commands contained in user EXEC mode, as well as the configure privileged EXEC command through which you access the remaining command modes.
Chapter 1 Using the Command-Line Interface CLI Command Modes Interface Configuration Mode Interface configuration commands modify the operation of the interface. Interface configuration commands always follow a global configuration command, which defines the interface type. Use the interface interface-id command to access interface configuration mode. The new prompt means interface configuration mode. Switch(config-if)# The supported commands can vary depending on the version of software in use.
Chapter 1 Using the Command-Line Interface CLI Command Modes To exit line configuration mode and to return to global configuration mode, use the exit command. To exit line configuration mode and to return to privileged EXEC mode, enter the end command, or press Ctrl-Z.

Chapter spanning-tree guard spanning-tree guard To enable root guard or loop guard on all the VLANs associated with the selected port, use the spanning-tree guard command in interface configuration mode. Root guard restricts which interface is allowed to be the spanning-tree root port or the path-to-the root for the switch. Loop guard prevents alternate or root ports from becoming designated ports when a failure creates a unidirectional link.

Chapter spanning-tree mst root When you enter the spanning-tree mst instance-id root secondary command, because of support for the extended system ID, the software changes the switch priority from the default value (32768) to 28672. If the root switch fails, this switch becomes the next root switch (if the other switches in the network use the default switch priority of 32768 and are therefore unlikely to become the root switch).
Chapter spanning-tree port-priority spanning-tree port-priority To configure an interface priority, use the spanning-tree port-priority command in interface configuration mode.

Chapter spanning-tree portfast (global configuration) spanning-tree portfast (global configuration) To globally enable bridge protocol data unit (BPDU) filtering on Port Fast-enabled interfaces, the BPDU guard feature on Port Fast-enabled STP ports, or the Port Fast feature on all nontrunking STP ports., use the spanning-tree portfast command in global configuration mode. The BPDU filtering feature prevents the switch STP port from sending or receiving BPDUs.
Chapter spanning-tree portfast (global configuration) Caution Enabling BPDU filtering on an STP port is the same as disabling spanning tree on it and can result in spanning-tree loops. Use the spanning-tree portfast bpduguard default global configuration command to globally enable BPDU guard on STP ports that are in a Port Fast-operational state. In a valid configuration, Port Fast-enabled STP ports do not receive BPDUs.
Chapter spanning-tree portfast (interface configuration) spanning-tree portfast (interface configuration) To enable the Port Fast feature on an STP port in all its associated VLANs, use the spanning-tree portfast command in interface configuration mode.

Chapter spanning-tree vlan Command Modes Global configuration Command History Release Modification 12.2(52)EY This command was introduced. Usage Guidelines Disabling the STP causes the VLAN to stop participating in the spanning-tree topology. STP ports that are administratively down remain down. Received BPDUs are forwarded like other multicast frames. The VLAN does not detect and prevent loops when STP is disabled.

Chapter speed speed To specify the speed of a 10/100/1000 Mbps port, use the speed interface configuration command. To return the port to its default value, use the no or default form of this command.
Chapter speed If the speed is set to auto, the switch negotiates with the device at the other end of the link for the speed setting and then forces the speed setting to the negotiated value. The duplex setting remains as configured on each end of the link, which could result in a duplex setting mismatch. If both ends of the line support autonegotiation, we highly recommend the default autonegotiation settings.
Chapter storm-control storm-control To enable broadcast, multicast, or unicast storm control and to set threshold levels on an interface, use the storm-control command in interface configuration mode. To return to the default setting, use the no form of this command.
Chapter storm-control level pps pps [pps-low] Specifies the rising and falling suppression levels as a rate in packets per second at which traffic is received on the port. • pps pps—The rising threshold level for broadcast, multicast, or unicast traffic in packets per second (up to one decimal place). The port blocks traffic when the rising threshold is reached. The range is 0.0 to 10000000000.0. • (Optional) pps-low,—The falling threshold level in packets per second (up to one decimal place).
Chapter storm-control Note When the storm control threshold for multicast traffic is reached, all multicast traffic except control traffic, such as bridge protocol data unit (BDPU) and Cisco Discovery Protocol (CDP) frames, are blocked. However, the switch does not differentiate between routing updates, such as Open Shortest Path First (OSPF) and regular multicast data traffic, so both types of traffic are blocked. The trap and shutdown options are independent of each other.
Chapter switchport switchport To put an interface that is in Layer 3 mode into Layer 2 mode for Layer 2 configuration, use the switchport command with no keywords in interface configuration mode. To put an interface in Layer 3 mode, use the no form of this command. switchport no switchport Note The switchport commands are not available on interfaces with service instances configured.

Configuration information for extended-range VLANs (VLAN IDs greater than 1005), are saved only in the switch running configuration file.
Chapter vlan Note The switch supports only Ethernet VLANs. You can configure parameters for FDDI and Token Ring VLANs and view the results in the vlan.dat file, but these parameters are not used. • are are-number: defines the maximum number of all-routes explorer (ARE) hops for TrCRF VLANs. The range is 0 to 13. The default is 7. • backupcrf {enable | disable}: specifies the backup CRF mode for TrCRF VLANs.

Translational VLANs translate FDDI or Token Ring to Ethernet, for example. The range is 0 to 1005. If no value is specified, 0 (no transitional bridging) is assumed. You can verify your setting by entering the show vlan privileged EXEC command.
Chapter vlan access-map vlan access-map To create or modify a VLAN map entry for VLAN packet filtering and to enter VLAN access-map configuration mode, use the vlan access-map command in global configuration mode.

You can also bind the VC to a pseudowire.
Chapter xconnect For H-VPLS, you create the VFI and enter VFI configuration mode by entering the l2 vfi vfi-name global configuration command. You can attach a VFI to a VLAN or to multiple Ethernet ports. The switch does not allow switching VLAN and port interfaces through the same VFI. The pw-class keyword with the pw-class-name value binds the xconnect configuration of an attachment circuit to a specific pseudowire class.
