Preface Cisco ME 3400 Ethernet Access Switch Command Reference xx OL-9640-07
CH A P T E R 1 Using the Command-Line Interface The Cisco Metro Ethernet (ME) 3400 Series Ethernet Access 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 3400 Ethernet Access 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 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands bandwidth bandwidth Use the bandwidth policy-map class configuration command to configure class-based weighted fair queuing (CBWFQ) by setting the output bandwidth for a policy-map class. Use the no form of this command to remove the bandwidth setting for the class.
Chapter 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands bandwidth The total rate of the minimum bandwidth guarantees for each queue of the policy cannot exceed the total speed for the interface. If the percent keyword is used, the sum of the class bandwidth percentages cannot exceed 100 percent. Using the queue-limit command to modify the default queue limit is especially important on higher-speed interfaces so that they meet the minimum bandwidth guarantees required by the interface.
Chapter 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands bandwidth This example shows how to set outclass1 as a priority queue, with outclass2, and outclass3 getting 50 and 20 percent, respectively, of the bandwidth remaining after the priority queue is serviced. The class class-default gets the remaining 30 percent with no guarantees.
Chapter 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands boot config-file boot config-file Use the boot config-file global configuration command to specify the filename that Cisco IOS uses to read and write a nonvolatile copy of the system configuration.

Chapter 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands channel-group on Enable on mode. In on mode, a usable EtherChannel exists only when both connected port groups are in the on mode. passive Enable LACP only if a LACP device is detected. Passive mode places a port into a negotiating state in which the port responds to LACP packets it receives but does not initiate LACP packet negotiation. A channel is formed only with another port group in active mode.
Chapter 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands channel-group In this case, running PAgP on a physical port prevents that port from ever becoming operational. However, it allows PAgP to operate, to attach the port to a channel group, and to use the port for transmission. Both ends of the link cannot be set to silent. In the on mode, an EtherChannel exists only when a port group in the on mode is connected to another port group in the on mode.

Appendix C Cisco ME 3400 Ethernet Access Switch Show Platform Commands show platform tcam show platform tcam Use the show platform tcam privileged EXEC command to display platform-dependent ternary content addressable memory (TCAM) driver information.
Appendix C Cisco ME 3400 Ethernet Access Switch Show Platform Commands show platform tcam table {acl | all | equal-cost-route Display lookup and forwarding table information. The keywords | ipv6 {acl | qos | secondary} have these meanings: local | mac-address | qos | • acl—Display the access-control list (ACL) table. secondary | station | vlan-list} • all—Display all the TCAM tables. usage • equal-cost-route—Display the equal-cost-route table. • local—Display the local table.
Appendix C Cisco ME 3400 Ethernet Access Switch Show Platform Commands show platform tcam Usage Guidelines You should use this command only when you are working directly with your technical support representative while troubleshooting a problem. Do not use this command unless your technical support representative asks you to do so. Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.
Appendix C Cisco ME 3400 Ethernet Access Switch Show Platform Commands show platform vlan show platform vlan Use the show platform vlan privileged EXEC command to display platform-dependent VLAN information. show platform vlan {misc | mvid | refcount | rpc {receive | transmit}} [ | {begin | exclude | include} expression] Syntax Description Note misc Display miscellaneous VLAN module information. mvid Display the mapped VLAN ID (MVID) allocation information.
