Using the Command-Line Interface Configuration Logging Table 2: Common CLI Error Messages Error Message Meaning How to Get Help % Ambiguous command: "show con" You did not enter enough characters for your switch to recognize the command. Reenter the command followed by a question mark (?) with a space between the command and the question mark. The possible keywords that you can enter with the command appear. % Incomplete command.
Using the Command-Line Interface Configuring the Command History Changing the Command History Buffer Size By default, the switch records ten command lines in its history buffer. You can alter this number for a current terminal session or for all sessions on a particular line. This procedure is optional. SUMMARY STEPS 1.
Using the Command-Line Interface Enabling and Disabling Editing Features Step 3 Command or Action Purpose show history Lists the last several commands that you just entered in privileged EXEC mode. The number of commands that appear is controlled by the setting of the terminal history global configuration command and the history line configuration command. Example: Switch# show history Disabling the Command History Feature The command history feature is automatically enabled.
Using the Command-Line Interface Enabling and Disabling Editing Features Step 2 Command or Action Purpose terminal no editing Disables the enhanced editing mode for the current terminal session in the privileged EXEC mode. Example: Switch# terminal no editing Editing Commands through Keystrokes The keystrokes help you to edit the command lines. These keystrokes are optional. Note The arrow keys function only on ANSI-compatible terminals such as VT100s.
Using the Command-Line Interface Enabling and Disabling Editing Features Esc D Deletes from the cursor to the end of the word. Esc C Capitalizes at the cursor. Esc L Changes the word at the cursor to lowercase. Esc U Capitalizes letters from the cursor to the end of the word. Ctrl-V or Esc Q Designates a particular keystroke as an executable command, perhaps as a shortcut. Return key Scrolls down a line or screen on displays that are longer than the terminal screen can display.
Using the Command-Line Interface Searching and Filtering Output of show and more Commands DETAILED STEPS Step 1 Command or Action Purpose access-list Displays the global configuration command entry that extends beyond one line. Example: When the cursor first reaches the end of the line, the line is shifted ten spaces to the left and redisplayed. The dollar sign ($) shows that the line has been scrolled to the left.
Using the Command-Line Interface Accessing the CLI through a Console Connection or through Telnet Command or Action Purpose Example: Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output are not displayed, but the lines that contain output appear.

CHAPTER 2 Configuring Interface Characteristics This module contains the following topics: • Finding Feature Information, page 13 • Information About Configuring Interface Characteristics, page 13 • How to Configure Interface Characteristics, page 23 • Monitoring Interface Characteristics, page 34 • Configuration Examples for Interface Characteristics, page 36 • Additional References for the Interface Characteristics Feature, page 38 • Feature History and Information for Configuring Interface Characterist
Configuring Interface Characteristics Interface Types Port-Based VLANs A VLAN is a switched network that is logically segmented by function, team, or application, without regard to the physical location of the users. Packets received on a port are forwarded only to ports that belong to the same VLAN as the receiving port. Network devices in different VLANs cannot communicate with one another without a Layer 3 device to route traffic between the VLANs.
Configuring Interface Characteristics Interface Types the VLAN membership of the port is discovered. Dynamic access ports on the switch are assigned to a VLAN by a VLAN Membership Policy Server (VMPS). The VMPS can be a Catalyst 6500 series switch; the switch cannot be a VMPS server. You can also configure an access port with an attached Cisco IP Phone to use one VLAN for voice traffic and another VLAN for data traffic from a device attached to the phone.
Configuring Interface Characteristics Interface Types Note When you create an SVI, it does not become active until it is associated with a physical port. SVI Autostate Exclude The line state of an SVI with multiple ports on a VLAN is in the up state when it meets these conditions: • The VLAN exists and is active in the VLAN database on the switch • The VLAN interface exists and is not administratively down.
Configuring Interface Characteristics Using the Switch USB Ports • a Cisco pre-standard powered device (such as a Cisco IP Phone or a Cisco Aironet Access Point) • an IEEE 802.3af-compliant powered device • an IEEE 802.3at-compliant powered device A powered device can receive redundant power when it is connected to a PoE switch port and to an AC power source. The device does not receive redundant power when it is only connected to the PoE port.
Configuring Interface Characteristics Interface Connections *Mar *Mar 1 00:01:00.171: %USB_CONSOLE-6-MEDIA_RJ45: Console media-type is RJ45. 1 00:01:00.431: %USB_CONSOLE-6-MEDIA_USB: Console media-type is USB. switch-stack-2 *Mar 1 00:01:09.835: %USB_CONSOLE-6-MEDIA_RJ45: Console media-type is RJ45. switch-stack-3 *Mar 1 00:01:10.523: %USB_CONSOLE-6-MEDIA_RJ45: Console media-type is RJ45.
Configuring Interface Characteristics Interface Configuration Mode In the following configuration example, when Host A in VLAN 20 sends data to Host B in VLAN 30, the data must go from Host A to the switch, to the router, back to the switch, and then to Host B. Figure 1: Connecting VLANs with the Switch With a standard Layer 2 switch, ports in different VLANs have to exchange information through a router.
Configuring Interface Characteristics Default Ethernet Interface Configuration gigabitethernet1/0/8. For a switch with 10/100/1000 ports and SFP module ports, SFP module ports are numbered consecutively following the 10/100/1000 ports. You can identify physical interfaces by physically checking the interface location on the switch. You can also use the show privileged EXEC commands to display information about a specific interface or all the interfaces on the switch.
Configuring Interface Characteristics Interface Speed and Duplex Mode Feature Default Setting EtherChannel (PAgP) Disabled on all Ethernet ports. Port blocking (unknown multicast and unknown unicast traffic) Disabled (not blocked). Broadcast, multicast, and unicast storm control Disabled. Protected port Disabled. Port security Disabled. Port Fast Disabled. Auto-MDIX Enabled.
Configuring Interface Characteristics IEEE 802.3x Flow Control ◦The 1000BASE-x (where -x is -BX, -CWDM, -LX, -SX, and -ZX) SFP module ports support the nonegotiate keyword in the speed interface configuration command. Duplex options are not supported. ◦The 1000BASE-T SFP module ports support the same speed and duplex options as the 10/100/1000-Mb/s ports. For information about which SFP modules are supported on your switch, see the product release notes.

Configuring PoE Information about PoE Information about PoE Power over Ethernet Ports A PoE-capable switch port automatically supplies power to one of these connected devices if the switch senses that there is no power on the circuit: • a Cisco pre-standard powered device (such as a Cisco IP Phone or a Cisco Aironet Access Point) • an IEEE 802.3af-compliant powered device • an IEEE 802.
Configuring PoE Power over Ethernet Ports Powered-Device Detection and Initial Power Allocation The switch detects a Cisco pre-standard or an IEEE-compliant powered device when the PoE-capable port is in the no-shutdown state, PoE is enabled (the default), and the connected device is not being powered by an AC adaptor.
Configuring PoE Power over Ethernet Ports Note The initial allocation for Class 0, Class 3, and Class 4 powered devices is 15.4 W. When a device starts up and uses CDP or LLDP to send a request for more than 15.4 W, it can be allocated up to the maximum of 30 W. Note The CDP-specific power consumption requirement is referred to as the actual power consumption requirement in the software configuration guides and command references.
Configuring PoE Power over Ethernet Ports a wattage, the switch delivers the maximum value. Use the auto setting on any PoE port. The auto mode is the default setting. • static—The switch pre-allocates power to the port (even when no powered device is connected) and guarantees that power will be available for the port. The switch allocates the port configured maximum wattage, and the amount is never adjusted through the IEEE class or by CDP messages from the powered device.
Configuring PoE Power over Ethernet Ports Maximum Power Allocation (Cutoff Power) on a PoE Port When power policing is enabled, the switch determines one of the these values as the cutoff power on the PoE port in this order: 1 Manually when you set the user-defined power level that the switch budgets for the port by using the power inline consumption default wattage global or interface configuration command 2 Manually when you set the user-defined power level that limits the power allowed on the port by us
Configuring PoE How to Configure PoE We recommend that you enable power policing when PoE is enabled on your switch. For example, if policing is disabled and you set the cutoff-power value by using the power inline auto max 6300 interface configuration command, the configured maximum power allocation on the PoE port is 6.3 W (6300 mW). The switch provides power to the connected devices on the port if the device needs up to 6.3 W.
Configuring PoE Budgeting Power for Devices Connected to a PoE Port DETAILED STEPS Step 1 Command or Action Purpose configure terminal Enters global configuration mode. Example: Switch# configure terminal Step 2 interface interface-id Specifies the physical port to be configured, and enters interface configuration mode. Example: Switch(config)# interface gigabitethernet2/0/1 Step 3 power inline {auto [max max-wattage] | Configures the PoE mode on the port.
Configuring PoE Budgeting Power for Devices Connected to a PoE Port grants a power request, the switch adjusts the power budget according to the powered-device IEEE classification. If the powered device is a class 0 (class status unknown) or a class 3, the switch budgets 15,400 mW for the device, regardless of the CDP-specific amount of power needed.
Configuring PoE Budgeting Power for Devices Connected to a PoE Port Step 3 Command or Action Purpose power inline consumption default wattage Configures the power consumption of powered devices connected to each the PoE port on the switch. Example: The range for each device is 4000 to 30000 mW (PoE+). The default is 30000 mW. Switch(config)# power inline consumption default 5000 Note Step 4 When you use this command, we recommend you also enable power policing. Returns to privileged EXEC mode.
Configuring PoE Configuring Power Policing Step 2 Command or Action Purpose no cdp run (Optional) Disables CDP. Example: Switch(config)# no cdp run Step 3 interface interface-id Specifies the physical port to be configured, and enter interface configuration mode. Example: Switch(config)# interface gigabitethernet2/0/1 Step 4 Step 5 power inline consumption wattage Configures the power consumption of a powered device connected to a PoE port on the switch.

Use one of the following: • errdisable detect cause inline-power • errdisable recovery cause inline-power • errdisable recovery interval interval 6. exit 7. Use one of the following: • show power inline police • show errdisable recovery DETAILED STEPS Step 1 Command or Action Purpose configure terminal Enters global configuration mode.
Configuring PoE Configuring Power Policing Command or Action Purpose • power inline police action log—Generates a syslog message while still providing power to the port. If you do not enter the action log keywords, the default action shuts down the port and puts the port in the error-disabled state. Step 4 Returns to global configuration mode.
Configuring PoE Monitoring Power Status Monitoring Power Status Table 11: Show Commands for Interfaces Command Purpose show env power switch [switch-number] (Optional) Displays the status of the internal power supplies for each switch in the stack or for the specified switch. The range is 1 to 9, depending on the switch member numbers in the stack. These keywords are available only on stacking-capable switches.

Configuring EEE Default EEE Configuration power by shutting down certain services. EEE provides the protocol needed to transition into and out of LPI mode in a way that is transparent to upper layer protocols and applications. Default EEE Configuration EEE is disabled by default. Restrictions for EEE EEE has the following restrictions: • Changing the EEE configuration resets the interface because the device has to restart Layer 1 autonegotiation.
Configuring EEE Monitoring EEE Step 2 Command or Action Purpose interface interface-id Specifies the interface to be configured, and enter interface configuration mode. Example: Switch(config)# interface gigabitethernet1/0/1 Step 3 Enables EEE on the specified interface. When EEE is enabled, the device advertises and autonegotiates EEE to its link partner. power efficient-ethernet auto Example: Switch(config-if)# power efficient-ethernet auto Step 4 Disables EEE on the specified interface.
