C H A P T E R 1 Using the Command-Line Interface The 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 of the commands that support these features, see Chapter 2, “CGESM Switch Cisco IOS Commands.” • For information on the bootloader commands, see Appendix A, “CGESM Switch Bootloader 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 User EXEC Mode After you access the device, you are automatically in user EXEC command mode. The EXEC commands available at the user level are a subset of those available at the privileged level. In general, use the user EXEC commands to temporarily change terminal settings, perform basic tests, and list system information. The supported commands can vary depending on the version of software in use.
Chapter 1 Using the Command-Line Interface CLI Command Modes The supported commands can vary depending on the version of software in use. To display a comprehensive list of commands, enter a question mark (?) at the prompt. Switch(config)# ? To exit global configuration command mode and to return to privileged EXEC mode, enter the end or exit command, or press Ctrl-Z. Interface Configuration Mode Interface configuration commands modify the operation of the interface.
Chapter 1 Using the Command-Line Interface CLI Command Modes VLAN Configuration Mode You can use the VLAN configuration commands to create or modify VLAN parameters for VLAN IDs 1 to 1005. Enter the vlan database privileged EXEC command to access VLAN configuration mode: Switch# vlan database Switch(vlan)# The supported commands can vary depending on the version of software in use. To display a comprehensive list of commands, enter a question mark (?) at the prompt.

The BPDU filtering feature prevents the switch interface from sending or receiving BPDUs.
Chapter 2 CGESM Switch Cisco IOS Commands spanning-tree portfast (global configuration) Caution Enabling BPDU filtering on an interface 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 interfaces that are in a Port Fast-operational state. In a valid configuration, Port Fast-enabled interfaces do not receive BPDUs.
Chapter 2 CGESM Switch Cisco IOS Commands spanning-tree portfast (interface configuration) spanning-tree portfast (interface configuration) Use the spanning-tree portfast interface configuration command to enable the Port Fast feature on an interface in all its associated VLANs.

Use the no form of this command to return to the default setting. srr-queue bandwidth shape weight1 weight2 weight3 weight4 no srr-queue bandwidth shape Syntax Description weight1 weight2 weight3 weight4 Defaults Weight1 is set to 25.
Chapter 2 CGESM Switch Cisco IOS Commands srr-queue bandwidth shape Examples This example shows how to configure the queues for the same port for both shaping and sharing. Because the weight ratios for queues 2, 3, and 4 are set to 0, these queues operate in shared mode. The bandwidth weight for queue 1 is 1/8, which is 12.5 percent. Queue 1 is guaranteed this bandwidth and limited to it; it does not extend its slot to the other queues even if the other queues have no traffic and are idle.
Chapter 2 CGESM Switch Cisco IOS Commands srr-queue bandwidth share srr-queue bandwidth share Use the srr-queue bandwidth share interface configuration command switch to assign the shared weights and to enable bandwidth sharing on the four egress queues mapped to a port. The ratio of the weights is the ratio of frequency in which the shaped round robin (SRR) scheduler dequeues packets from each queue. Use the no form of this command to return to the default setting.
Chapter 2 CGESM Switch Cisco IOS Commands srr-queue bandwidth share Examples This example shows how to configure the weight ratio of the SRR scheduler running on an egress port. Four queues are used. The bandwidth ratio allocated for each queue in shared mode is 1/(1+2+3+4), 2/(1+2+3+4), 3/(1+2+3+4), and 4/(1+2+3+4), which is 10 percent, 20 percent, 30 percent, and 40 percent for queues 1, 2, 3, and 4.

The range is 0.0 to 10000000000.0.
Chapter 2 CGESM Switch Cisco IOS Commands storm-control If you configure the action to be taken as shutdown (the port is error-disabled during a storm) when a packet storm is detected, you must use the no shutdown interface configuration command to bring the interface out of this state. If you do not specify the shutdown action, specify the action as trap (the switch generates a trap when a storm is detected).
Chapter 2 CGESM Switch Cisco IOS Commands switchport access switchport access Use the switchport access interface configuration command to configure a port as a static-access or dynamic-access port. If the switchport mode is set to access, the port operates as a member of the specified VLAN.

Chapter 2 CGESM Switch Cisco IOS Commands switchport access • Use dynamic-access ports only to connect end stations. Connecting them to switches or routers (that use bridging protocols) can cause a loss of connectivity. • Configure the network so that STP does not put the dynamic-access port into an STP blocking state.
