rmon collection stats

Use the rmon collection stats interface configuration command to collect Ethernet group statistics, which include usage statistics about broadcast and multicast packets, and error statistics about cyclic redundancy check (CRC) alignment errors and collisions. Use the no form of this command to return to the default setting.

rmon collection stats index [owner name]

no rmon collection stats index [owner name]

Syntax Description

index	Remote Network Monitoring (RMON) collection control index. The range is 1 to 65535.
owner name	(Optional) Owner of the RMON collection.

Defaults

The RMON statistics collection is disabled.

Command Modes

Interface configuration

Command History

Release	Modification
12.1(19)EA1	This command was introduced.

Usage Guidelines

The RMON statistics collection command is based on hardware counters.

Examples

This example shows how to collect RMON statistics for the owner root:

Switch(config)# interface gigabitethernet0/1

Switch(config-if)# rmon collection stats 2 owner root

You can verify your setting by entering the show rmon statistics privileged EXEC command.

Related Commands

Command	Description
show rmon statistics	Displays RMON statistics. For syntax information, select Cisco IOS Configuration Fundamentals Command Reference, Release 12.2 > System Management Commands > RMON Commands.

sdm prefer

Use the sdm prefer global configuration command on the switch to configure the template used in Switch Database Management (SDM) resource allocation. You can use a template to allocate system resources to best support the features being used in your application. Use a template to provide maximum system usage for unicast routing or for VLAN configuration, or to select the dual IPv4 and IPv6 template to support IPv6 forwarding (supported only when the switch is running the advanced IP services image). Use the no form of this command to return to the default template.

sdm prefer {access | default | dual-ipv4-and-ipv6 {default | routing | vlan} | routing | vlan}

no sdm prefer

Syntax Description

access	Provide maximum system usage for access control lists (ACLs). Use this template if you have a large number of ACLs.
default	Give balance to all functions.
dual-ipv4-and-ipv6 {default | routing | vlan}	Select a template that supports both IPv4 and IPv6 routing. •default—Provide balance to IPv4 and IPv6 Layer 2 and Layer 3 functionality. •routing—Provide maximum system usage for IPv4 and IPv6 routing, including IPv4 policy-based routing. •vlan—Provide maximum system usage for IPv4 and IPv6 VLANs.
routing	Provide maximum system usage for unicast routing. You would typically use this template for a router or aggregator in the middle of a network.
vlan	Provide maximum system usage for VLANs. This template maximizes system resources for use as a Layer 2 switch with no routing.

Defaults

The default template provides a balance to all features.

Command Modes

Global configuration

Command History

Release	Modification
12.1(19)EA1	This command was introduced.
12.2(25)SEA	The dual-ipv4-and-ipv6 templates were added.
12.2(25)SED	The access templates were added.
12.2(25)SEE	The dual-ipv4-and-ipv6 routing template was added.

Usage Guidelines

You must reload the switch for the configuration to take effect. If you enter the show sdm prefer command before you enter the reload privileged EXEC command, the show sdm prefer command shows the template currently in use and the template that will become active after a reload.

Use the no sdm prefer command to set the switch to the default desktop template.

The access template maximizes system resources for access control lists (ACLs) as required to accommodate a large number of ACLs.

The default template balances the use of system resources.

Use the sdm prefer vlan global configuration command only on switches intended for Layer 2 switching with no routing. When you use the VLAN template, no system resources are reserved for routing entries, and any routing is done through software. This overloads the CPU and severely degrades routing performance.

Do not use the routing template if you do not have routing enabled on your switch. Entering the sdm prefer routing global configuration command prevents other features from using the memory allocated to unicast routing in the routing template.

Do not use the ipv4-and-ipv6 templates if you do not plan to enable IPv6 routing on the switch. Entering the sdm prefer ipv4-and-ipv6 {default | routing | vlan} global configuration command divides resources between IPv4 and IPv6, limiting those allocated to IPv4 forwarding.

Table 2-15 lists the approximate number of each resource supported in each of the IPv4-only templates for a switch. The values in the template are based on eight routed interfaces and approximately one thousand VLANs and represent the approximate hardware boundaries set when a template is selected. If a section of a hardware resource is full, all processing overflow is sent to the CPU, seriously impacting switch performance.

Table 2-15 Approximate Number of Feature Resources Allowed by Each Template

Resource	Access	Default	Routing	VLAN
Unicast MAC addresses	4 K	6 K	3 K	12 K
IGMP groups and multicast routes	1 K	1 K	1 K	1 K

service password-recovery

Use the service password-recovery global configuration command to enable the password-recovery mechanism (the default). This mechanism allows an end user with physical access to the switch to hold down the Mode button and interrupt the bootup process while the switch is powering up and to assign a new password. Use the no form of this command to disable part of the password-recovery functionality. When the password-recovery mechanism is disabled, interrupting the bootup process is allowed only if the user agrees to set the system back to the default configuration.

service password-recovery

no service password-recovery

Syntax Description

This command has no arguments or keywords.

Defaults

The password-recovery mechanism is enabled.

Command Modes

Global configuration

Command History

Release	Modification
12.1(19)EA1	This command was introduced.

Usage Guidelines

As a system administrator, you can use the no service password-recovery command to disable some of the functionality of the password recovery feature by allowing an end user to reset a password only by agreeing to return to the default configuration.

To use the password-recovery procedure, a user with physical access to the switch holds down the Mode button while the unit powers up and for a second or two after the LED above port 1X turns off. When the button is released, the system continues with initialization.

If the password-recovery mechanism is disabled, this message appears:

The password-recovery mechanism has been triggered, but

is currently disabled.  Access to the boot loader prompt

through the password-recovery mechanism is disallowed at

this point.  However, if you agree to let the system be

reset back to the default system configuration, access

to the boot loader prompt can still be allowed.

Would you like to reset the system back to the default configuration (y/n)?

---

Note If the user chooses not to reset the system to the default configuration, the normal bootup process continues, as if the Mode button had not been pressed. If you choose to reset the system to the default configuration, the configuration file in flash memory is deleted, and the VLAN database file, flash:vlan.dat (if present), is deleted.If you use the no service password-recovery command to control end user access to passwords, we recommend that you save a copy of the config file in a location away from the switch in case the end user uses the password recovery procedure and sets the system back to default values. Do not keep a backup copy of the config file on the switch.

If the switch is operating in VTP transparent mode, we recommend that you also save a copy of the vlan.dat file in a location away from the switch.

---

You can verify if password recovery is enabled or disabled by entering the show version privileged EXEC command.

Examples

This example shows how to disable password recovery on a switch so that a user can only reset a password by agreeing to return to the default configuration.

Switch(config)# no service-password recovery

Switch(config)# exit

Command	Description
show version	Displays version information for the hardware and firmware.

service-policy

Use the service-policy interface configuration command on the switch to apply a policy map defined by the policy-map command to the input of a physical port or a switch virtual interface (SVI). Use the no form of this command to remove the policy map and port association.

service-policy input policy-map-name

no service-policy input policy-map-name

Syntax Description

input policy-map-name

Apply the specified policy map to the input of a physical port or an SVI.

---

Note Though visible in the command-line help strings, the history keyword is not supported, and you should ignore the statistics that it gathers. The output keyword is also not supported.

---

Defaults

No policy maps are attached to the port.

Command Modes

Interface configuration

Command History

Release	Modification
12.1(19)EA1	This command was introduced.
12.2(25)SE	A policy map can now be applied to a physical port or an SVI.
12.2(25)SED	Hierarchical policy-maps can now be applied to an SVI.

Usage Guidelines

Only one policy map per ingress port is supported. In software releases earlier than Cisco IOS Release 12.2(25)SE, policy maps can be configured only on physical ports.

In Cisco IOS Release 12.2(25)SE or later, policy maps can be configured on physical ports or on SVIs. When VLAN-based quality of service (QoS) is disabled by using the no mls qos vlan-based interface configuration command on a physical port, you can configure a port-based policy map on the port. If VLAN-based QoS is enabled by using the mls qos vlan-based interface configuration command on a physical port, the switch removes the previously configured port-based policy map. After a hierarchical policy map is configured and applied on an SVI, the interface-level policy map takes effect on the interface.

In software releases earlier than Cisco IOS Release 12.2(25)SE, you can apply a policy map only to the incoming traffic on a physical port. In Cisco IOS Release 12.2(25)SE or later, you can apply a policy map to incoming traffic on a physical port or on an SVI. In Cisco IOS Release 12.2(25)SED or later, you can configure different interface-level policy maps for each class defined in the VLAN-level policy map. For more information about hierarchical policy maps, see the "Configuring QoS" chapter in the software configuration guide for this release.

Classification using a port trust state (for example, mls qos trust [cos | dscp | ip-precedence] and a policy map (for example, service-policy input policy-map-name) are mutually exclusive. The last one configured overwrites the previous configuration.

Examples

This example shows how to apply plcmap1 to an physical ingress port:

Switch(config)# interface gigabitethernet0/1

Switch(config-if)# service-policy input plcmap1

This example shows how to remove plcmap2 from a physical port:

Switch(config)# interface gigabitethernet0/2

Switch(config-if)# no service-policy input plcmap2

This example shows how to apply plcmap1 to an ingress SVI when VLAN-based QoS is enabled:

Switch(config)# interface vlan 10

Switch(config-if)# service-policy input plcmap1

This example shows how to create a hierarchical policy map and attach it to an SVI:

set

Use the set policy-map class configuration command to classify IP traffic by setting a Differentiated Services Code Point (DSCP) or an IP-precedence value in the packet. Use the no form of this command to remove traffic classification.

set {dscp new-dscp | [ip] precedence new-precedence}

no set {dscp new-dscp | [ip] precedence new-precedence}

Syntax Description

dscp new-dscp	New DSCP value assigned to the classified traffic. The range is 0 to 63. You also can enter a mnemonic name for a commonly used value.
[ip] precedence new-precedence	New IP-precedence value assigned to the classified traffic. The range is 0 to 7. You also can enter a mnemonic name for a commonly used value.

Defaults

No traffic classification is defined.

Command Modes

Policy-map class configuration

Command History

Release	Modification
12.1(19)EA1	This command was introduced.
12.2(25)SE	The ip dscp new-dscp keyword was changed to dscp new-dscp. The set dscp new-dscp command replaces the set ip dscp new-dscp command.
12.2(25)SEC	The ip keyword is optional.

Usage Guidelines

In Cisco IOS Release 12.2(25)SE or later, if you have used the set ip dscp policy-map class configuration command, the switch changes this command to set dscp in the switch configuration. If you enter the set ip dscp policy-map class configuration command, this setting appears as set dscp in the switch configuration.

In Cisco IOS Release 12.2(25)SEC or later, you can use the set ip precedence policy-map class configuration command or the set precedence policy-map class configuration command. This setting appears as set ip precedence in the switch configuration.

The set command is mutually exclusive with the trust policy-map class configuration command within the same policy map.

For the set dscp new-dscp or the set ip precedence new-precedence command, you can enter a mnemonic name for a commonly used value. For example, you can enter the set dscp af11 command, which is the same as entering the set dscp 10 command. You can enter the set ip precedence critical command, which is the same as entering the set ip precedence 5 command. For a list of supported mnemonics, enter the set dscp ? or the set ip precedence ? command to see the command-line help strings.

To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode, use the end command.

Examples

This example shows how to assign DSCP 10 to all FTP traffic without any policers:

Switch(config)# policy-map policy_ftp

Switch(config-pmap)# class ftp_class

Switch(config-pmap-c)# set dscp 10

Switch(config-pmap)# exit

You can verify your settings by entering the show policy-map privileged EXEC command.

setup express

Use the setup express global configuration command to enable Express Setup mode. Use the no form of this command to disable Express Setup mode.

setup express

no setup express

Syntax Description

This command has no arguments or keywords.

Defaults

Express Setup is enabled.

Command Modes

Global configuration

Command History

Release	Modification
12.1(19)EA1	This command was introduced.

Usage Guidelines

When Express Setup is enabled on a new (unconfigured) switch, pressing the Mode button for 2 seconds activates Express Setup. You can access the switch through an Ethernet port by using the IP address 10.0.0.1 and then can configure the switch with the web-based Express Setup program or the command-line interface (CLI)-based setup program.

When you press the Mode button for 2 seconds on a configured switch, the LEDs above the Mode button start blinking. If you press the Mode button for a total of 10 seconds, the switch configuration is deleted, and the switch reboots. The switch can then be configured like a new switch, either through the web-based Express Setup program or the CLI-based setup program.

---

Note As soon as you make any change to the switch configuration (including entering no at the beginning of the CLI-based setup program), configuration by Express Setup is no longer available. You can only run Express Setup again by pressing the Mode button for 10 seconds. This deletes the switch configuration and reboots the switch.

---

If Express Setup is active on the switch, entering the write memory or copy running-configuration startup-configuration privileged EXEC commands deactivates Express Setup. The IP address 10.0.0.1 is no longer valid on the switch, and your connection using this IP address ends.

The primary purpose of the no setup express command is to prevent someone from deleting the switch configuration by pressing the Mode button for 10 seconds.

Examples

This example shows how to enable Express Setup mode:

Switch(config)# setup express

You can verify that Express Setup mode is enabled by pressing the Mode button:

•On an unconfigured switch, the LEDs above the Mode button turn solid green after 3 seconds.

•On a configured switch, the mode LEDs begin blinking after 2 seconds and turn solid green after 10 seconds.

---

Caution If you hold the Mode button down for a total of 10 seconds, the configuration is deleted, and the switch reboots.

---

This example shows how to disable Express Setup mode:

Switch(config)# no setup express

You can verify that Express Setup mode is disabled by pressing the Mode button. The mode LEDs do not turn solid green or begin blinking green if Express Setup mode is not enabled on the switch.

Related Commands

Command	Description
show setup express	Displays if Express Setup mode is active.

show access-lists

Command Modes

Privileged EXEC

Command History

Release	Modification
12.1(19)EA1	This command was introduced.

Usage Guidelines

The switch supports only IP standard and extended access lists. Therefore, the allowed numbers are only 1 to 199 and 1300 to 2699.

This command also displays the MAC ACLs that are configured.

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 are displayed.

Examples

This is an example of output from the show access-lists command:

Table 2-17 show boot Field Descriptions

Field	Description
BOOT path-list	Displays a semicolon separated list of executable files to try to load and execute when automatically booting up. If the BOOT environment variable is not set, the system attempts to load and execute the first executable image it can find by using a recursive, depth-first search through the flash file system. In a depth-first search of a directory, each encountered subdirectory is completely searched before continuing the search in the original directory. If the BOOT variable is set but the specified images cannot be loaded, the system attempts to boot up with the first bootable file that it can find in the flash file system.
Config file	Displays the filename that Cisco IOS uses to read and write a nonvolatile copy of the system configuration.
Private Config file	Displays the filename that Cisco IOS uses to read and write a nonvolatile copy of the system configuration.
Enable Break	Displays whether a break during booting up is enabled or disabled. If it is set to yes, on, or 1, you can interrupt the automatic bootup process by pressing the Break key on the console after the flash file system is initialized.
Manual Boot	Displays whether the switch automatically or manually boots up. If it is set to no or 0, the bootloader attempts to automatically boot up the system. If it is set to anything else, you must manually boot up the switch from the bootloader mode.
Helper path-list	Displays a semicolon separated list of loadable files to dynamically load during the bootloader initialization. Helper files extend or patch the functionality of the bootloader.
NVRAM/Config file buffer size	Displays the buffer size that Cisco IOS uses to hold a copy of the configuration file in memory. The configuration file cannot be larger than the buffer size allocation.

Usage Guidelines

If you enter this command on a switch that is not a cluster member, the error message Not a management cluster member appears.

On a cluster member switch, this command displays the identity of the cluster command switch, the switch member number, and the state of its connectivity with the cluster command switch.

On a cluster command switch, this command displays the cluster name and the total number of members. It also shows the cluster status and time since the status changed. If redundancy is enabled, it displays the primary and secondary command-switch information.

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 are displayed.

Examples

This is an example of output when the show cluster command is entered on the active cluster command switch:

Switch> show cluster

Command switch for cluster "Ajang"

        Total number of members:        7

        Status:                         1 members are unreachable

        Time since last status change:  0 days, 0 hours, 2 minutes

        Redundancy:                     Enabled

                Standby command switch: Member 1

                Standby Group:          Ajang_standby

                Standby Group Number:   110

        Heartbeat interval:             8

        Heartbeat hold-time:            80

        Extended discovery hop count:   3 

This is an example of output when the show cluster command is entered on a cluster member switch:

Switch1> show cluster

Member switch for cluster "hapuna"

        Member number:                  3

        Management IP address:          192.192.192.192

        Command switch mac address:     0000.0c07.ac14

        Heartbeat interval:             8

        Heartbeat hold-time:            80 

This is an example of output when the show cluster command is entered on a cluster member switch that is configured as the standby cluster command switch:

Switch> show cluster

Member switch for cluster "hapuna"

        Member number:                  3 (Standby command switch)

        Management IP address:          192.192.192.192

        Command switch mac address:     0000.0c07.ac14

        Heartbeat interval:             8

        Heartbeat hold-time:            80 

This is an example of output when the show cluster command is entered on the cluster command switch that has lost connectivity with member 1:

Switch> show cluster

Command switch for cluster "Ajang"

        Total number of members:        7

        Status:                         1 members are unreachable

        Time since last status change:  0 days, 0 hours, 5 minutes

        Redundancy:                     Disabled

        Heartbeat interval:             8

        Heartbeat hold-time:            80

        Extended discovery hop count:   3 

This is an example of output when the show cluster command is entered on a cluster member switch that has lost connectivity with the cluster command switch:

12.1(19)EA1	This command was introduced.

Usage Guidelines

This command is available only on the cluster command switch.

If the switch is not a cluster command switch, the command displays an empty line at the prompt.

The SN in the display means switch member number. If E appears in the SN column, it means that the switch is discovered through extended discovery. If E does not appear in the SN column, it means that the switch member number is the upstream neighbor of the candidate switch. The hop count is the number of devices the candidate is from the cluster command switch.

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 are displayed.

Examples

This is an example of output from the show cluster candidates command:

Switch> show cluster candidates

show interfaces	Displays the administrative and operational status of all interfaces or a specified interface.

show controllers ethernet-controller

Use the show controllers ethernet-controller privileged EXEC command without keywords to display per-interface send and receive statistics read from the hardware. Use with the phy keyword to display the interface internal registers or the port-asic keyword to display information about the port ASIC.

show controllers ethernet-controller [interface-id] [phy [detail]] [port-asic {configuration | statistics}] [fastethernet 0][ | {begin | exclude | include} expression]

Syntax Description

interface-id	The physical interface (including type, module, and port number).
phy	(Optional) Display the status of the internal registers on the switch physical layer device (PHY) for the device or the interface. This display includes the operational state of the automatic medium-dependent interface crossover (auto-MDIX) feature on an interface.
detail	(Optional) Display details about the PHY internal registers.
port-asic	(Optional) Display information about the port ASIC internal registers.
configuration	Display port ASIC internal register configuration.
statistics	Display port ASIC statistics, including the Rx/Sup Queue and miscellaneous statistics.
| begin	(Optional) Display begins with the line that matches the expression.
| exclude	(Optional) Display excludes lines that match the expression.
| include	(Optional) Display includes lines that match the specified expression.
expression	Expression in the output to use as a reference point.

Command Modes

Privileged EXEC (only supported with the interface-id keywords in user EXEC mode)

Command History

Release	Modification
12.1(19)EA1	This command was introduced.

Usage Guidelines

This display without keywords provides traffic statistics, basically the RMON statistics for all interfaces or for the specified interface.

When you enter the phy or port-asic keywords, the displayed information is useful primarily for Cisco technical support representatives troubleshooting the switch.

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 are displayed.

Command History

Release	Modification
12.1(19)EA1	This command was introduced.
12.2(20)SE3	The temperature status keyword was added.

Usage Guidelines

Though visible on all switches, the show env temperature status command is valid only for the Catalyst 3560G-48TS, 3560G-48PS, 3560G-24TS, and 3560G-24PS switches. If you enter this command on these switches, the command output shows the switch temperature states and the threshold levels. If you enter the command on a switch other than these four switches, the output field shows Not Applicable.

On a Catalyst 3560G-48PS or 3560G-24PS switch, you can also use the show env temperature command to display the switch temperature status. The command output shows the green and yellow states as OK and the red state as FAULTY. If you enter the show env all command on this switch, the command output is the same as the show env temperature status command output.

For more information about the threshold levels, see the software configuration guide for this release.

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 are displayed.

Examples

This is an example of output from the show env all command:

Switch> show env all

FAN is OK

TEMPERATURE is OK

POWER is OK

RPS is AVAILABLE

This is an example of output from the show env fan command:

Switch> show env fan

FAN is OK

This example shows how to display the temperature value, state, and the threshold values. Table 2-23 describes the temperature states in the command output.

Switch> show env temperature status

Temperature Value:28 Degree Celsius

Temperature State:GREEN

Yellow Threshold :70 Degree Celsius
