sdm prefer
Use the sdm prefer global configuration command 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, to change an aggregator template (Catalyst 3750-12S only) to a desktop template, or to select the dual IPv4 and IPv6 template to support IPv6 forwarding. 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 } [ desktop ]
Syntax Description
Defaults
Command Modes
Command History
|
|
|
|---|---|
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.
Desktop switches support only desktop templates; an aggregator switch (Catalyst 3750-12S) supports both desktop and aggregator templates. On an aggregator switch, if you do not enter the desktop keyword, the aggregator templates are selected.
All stack members use the same SDM desktop or aggregator template, stored on the stack master. When a new switch member is added to a stack, as with the switch configuration file and VLAN database file, the SDM configuration that is stored on the master overrides the template configured on an individual switch.
To route IPv6 packets in a stack of switches, all switches in the stack should be running the IP services image. The IPv6 packets are routed in hardware across the stack, as long as the packet does not have exceptions (IPv6Options) and the switches have not run out of hardware resources.
If a member cannot support the template that is running on the master switch, the switch goes into SDM mismatch mode, the master switch does not attempt to change the SDM template, and the switch cannot be a functioning member of the stack.
- If the master switch is a Catalyst 3750-12S, and you change the template from an aggregator template to a desktop template and reload the switch, the entire stack operates with the selected desktop template. This could cause configuration losses if the number of ternary content addressable memory (TCAM) entries exceeds the desktop template sizes.
- If you change the template on a Catalyst 3750-12S master from a desktop template to an aggregator template and reload the switch, any desktop switches that were part of the stack go into SDM mismatch mode.
- If you add a Catalyst 3750-12S switch that is running the aggregator template to a stack that has a desktop switch as the master, the stack operates with the desktop template selected on the master. This could cause configuration losses on the Catalyst 3750-12S member if the number of TCAM entries on it exceeds desktop template sizes.
For more information about stacking, see the “Managing Switch Stacks” chapter in the software configuration guide.
The access template maximizes system resources for access control lists (ACLs) as required to accommodate a large number of ACLs.
The default templates balance the use of system resources.
Use the sdm prefer vlan [ desktop ] 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 [ desktop ] 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 } [ desktop ] global configuration command divides resources between IPv4 and IPv6, limiting those allocated to IPv4 forwarding.
Table 0-1 lists the approximate number of each resource supported in each of the IPv4-only templates for a desktop or aggregator 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 0-2 lists the approximate number of each resource supported in each of the dual IPv4-and IPv6 templates for a desktop or aggregator switch.

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.
Syntax Description

Command Modes
Command History
|
|
|
|---|---|
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:
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.
When you enter the service password-recovery or no service password-recovery command on the stack master, it is propagated throughout the stack and applied to all switches in the stack.
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 or switch stack so that a user can only reset a password by agreeing to return to the default configuration.

|---|---|
A policy map can now be applied to a physical port or an SVI. |
|
Usage Guidelines
Only one policy map per ingress port is supported.
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.
You can apply a policy map to incoming traffic on a physical port or on an SVI. 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.
Policy maps that use the police aggregate command fail when applied to a 10-Gigabit Ethernet interface.

This example shows how to apply plcmap1 to an physical ingress port:
This example shows how to remove plcmap2 from a physical port:

|---|---|
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. |
|
Usage Guidelines
If you have used the set ip dscp p olicy-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.
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:
You can verify your settings by entering the show policy-map privileged EXEC command.

Syntax Description
Defaults
Command Modes
Command History
|
|
|
|---|---|
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:
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.
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:
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.

Usage Guidelines
Use the show ipv6 mld snooping querier command to display the MLD version and IPv6 address of a detected device that sends MLD query messages, which is also called a querier. A subnet can have multiple multicast routers but has only one MLD querier. The querier can be a Layer 3 switch.
The show ipv6 mld snooping querier command output also shows the VLAN and interface on which the querier was detected. If the querier is the switch, the output shows the Port field as Router. If the querier is a router, the output shows the port number on which the querier is learned in the Port field.
The output of the show ipv6 mld snoop querier vlan command displays the information received in response to a query message from an external or internal querier. It does not display user-configured VLAN values, such as the snooping robustness variable on the particular VLAN. This querier information is used only on the MASQ message that is sent by the switch. It does not override the user-configured robustness variable that is used for aging out a member that does not respond to query messages.
VLAN numbers 1002 through 1005 are reserved for Token Ring and FDDI VLANs and cannot be used in MLD snooping.
To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 global configuration command and reload the switch.

The policed-DSCP, DSCP-to-CoS, and the DSCP-to-DSCP-mutation maps appear as a matrix. The d1 column specifies the most-significant digit in the DSCP. The d2 row specifies the least-significant digit in the DSCP. The intersection of the d1 and d2 values provides the policed-DSCP, the CoS, or the mutated-DSCP value. For example, in the DSCP-to-CoS map, a DSCP value of 43 corresponds to a CoS value of 5.
The DSCP input queue threshold and the DSCP output queue threshold maps appear as a matrix. The d1 column specifies the most-significant digit of the DSCP number. The d2 row specifies the least-significant digit in the DSCP number. The intersection of the d1 and the d2 values provides the queue ID and threshold ID. For example, in the DSCP input queue threshold map, a DSCP value of 43 corresponds to queue 2 and threshold 1 (02-01).
The CoS input queue threshold and the CoS output queue threshold maps show the CoS value in the top row and the corresponding queue ID and threshold ID in the second row. For example, in the CoS input queue threshold map, a CoS value of 5 corresponds to queue 2 and threshold 1 (2-1).

Command History
Usage Guidelines
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.
This command displays these states:
- Waiting—A switch is booting up and waiting for communication from other switches in the stack. The switch has not yet determined whether or not it is a stack master.
Stack members not participating in a stack master election remain in the waiting state until the stack master is elected and ready.
- Initializing—A switch has determined whether its stack master status. If it is not the stack master, it is receiving its system- and interface-level configuration from the stack master and loading it.
- Ready—The member has completed loading the system- and interface-level configurations and can forward traffic.
- Master Re-Init—The state immediately after a master re-election and a different member is elected master. The new master is re-initializing its configuration. This state applies only to the new master.
- Ver Mismatch—A switch in version mismatch mode. Version-mismatch mode is when a switch joining the stack has a different stack protocol minor version number than the master.
- SDM Mismatch—A switch in Switch Database Management (SDM) mismatch mode. SDM mismatch is when a member does not support the SDM template running on the master.
- Provisioned—The state of a preconfigured switch before it becomes an active member of a stack, or the state of a member after it has left the stack. The MAC address and the priority number in the display are always 0 for the provisioned switch.
A typical state transition for a member (including a master) booting up is Waiting -> Initializing -> Ready.
A typical state transition for a member becoming a master after a master election is Ready -> Master Re-Init -> Ready.
A typical state transition for a member in version mismatch mode is Waiting -> Ver Mismatch.
You can use the show switch command to identify whether the provisioned switch exists in the stack. The show running-config and the show startup-config privileged EXEC commands do not provide this information.
The display also includes stack MAC-persistency wait-time if persistent MAC address is enabled.

In the show vlan mtu command output, the MTU_Mismatch column shows whether all the ports in the VLAN have the same MTU. When yes appears in this column, it means that the VLAN has ports with different MTUs, and packets that are switched from a port with a larger MTU to a port with a smaller MTU might be dropped. If the VLAN does not have an SVI, the hyphen (-) symbol appears in the SVI_MTU column. If the MTU-Mismatch column displays yes, the names of the port with the MinMTU and the port with the MaxMTU appear.
If you try to associate a private VLAN secondary VLAN with a primary VLAN before you define the secondary VLAN, the secondary VLAN is not included in the show vlan private-vlan command output.
In the show vlan private-vlan type command output, a type displayed as normal means a VLAN that has a private VLAN association but is not part of the private VLAN. For example, if you define and associate two VLANs as primary and secondary VLANs and then delete the secondary VLAN configuration without removing the association from the primary VLAN, the VLAN that was the secondary VLAN is shown as normal in the display. In the show vlan private-vlan output, the primary and secondary VLAN pair is shown as non-operational.
