Usage Guidelines

The undebug platform remote-commands command is the same as the no debug platform remote-commands command.

When you enable debugging on a switch stack, it is enabled only on the active switch. To enable debugging on a stack member, you can start a session from the stack's active switch by using the session switch-number privileged EXEC command. Enter the debug command at the command-line prompt of the stack member. You also can use the remote command stack-member-number LINE privileged EXEC command on the active switch to enable debugging on a member switch without first starting a session.

debug platform stack-manager

To enable debugging of the stack manager software, use the debug platform stack-manager command in privileged EXEC mode. To disable debugging, use the no form of this command.

debug platform stack-manager {all | rpc | sdp | sim | ssm | tdm | trace}

no debug platform stack-manager {all | rpc | sdp | sim | ssm | tdm | trace}

Syntax Description

all

Displays all stack manager debug messages.

rpc

Displays stack manager remote procedure call (RPC) usage debug messages.

sdp

Displays the Stack Discovery Protocol (SDP) debug messages.

sim

Displays the stack information module debug messages.

ssm

Displays the stack state-machine debug messages.

tdm

Displays the stack manager topology discovery use debug messages.

trace

Release Modification

Cisco IOS Release 15.0(2)EX

This command was introduced.

Usage Guidelines

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.


Note

This command is supported only on stacking-capable switches.


The summary information about the switch stack shows these states:

  • Waiting—A switch is booting up and waiting for communication from other switches in the stack. The switch has not determined whether or not it is active switch.

    Stack members not participating in election remain in the waiting state until the active switch is elected and ready.

  • Initializing—A switch has determined whether it is the active switch. If not, the switch receives its system- and interface-level configuration from the active switch and loads it.

  • Ready—The member has completed loading the system- and interface-level configurations and can forward traffic.

  • Ver Mismatch—A switch in version mismatch mode. Version-mismatch mode is when a switch that joins the stack has a different stack protocol minor version number than the active switch.

A typical state transition for a stack member (including the active) booting up is Waiting > Initializing > Ready.

A typical state transition for a stack member to active switch after an election is Ready > Re-Init > Ready.

A typical state transition for a stack member in version mismatch (VM) mode is Waiting > Ver Mismatch.

show switch

To display information that is related to the stack member or the switch stack, use the show switch command in EXEC mode.

show switch [stack-member-number | detail | neighbors | stack-ports | stack-ring speed]


Note

This command is supported only on Catalyst 2960-X switches running the LAN Base image.

Syntax Description

stack-member-number

(Optional) Number of the stack member. The range is 1 to 8.

detail

(Optional) Displays detailed information about the stack ring.

neighbors

(Optional) Displays the neighbors of the entire switch stack.

stack-ports

(Optional) Displays port information for the entire switch stack.

stack-ring

(Optional) Displays information about the stack ring.

speed

Displays the stack ring speed.

Command Default

None

Command Modes

Command History

Release Modification

Cisco IOS Release 15.0(2)EX

This command was introduced.

Usage Guidelines

This command output displays these states:

  • Waiting—A switch is booting up and waiting for communication from other switches in the stack. The switch has not determined whether or not it is an active stack.

    Stack members not participating in a active stack election remain in the waiting state until the active stack is elected and ready.

  • Initializing—A switch has determined whether it has the active stack status. If it is not the active stack, it receives and loads the system- and interface-level configuration from the active stack.

  • Ready—The member has completed loading the system- and interface-level configurations and can forward traffic.

  • 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 active stack.

  • 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 active stack.

  • Provisioned—The state of a preconfigured switch before it becomes an active member of a switch stack, or the state of a stack member after it has left the switch stack. The MAC address and the priority number in the display are always 0 for the provisioned switch.

A typical state transition for a stack member (including the active) booting up is Waiting > Initializing > Ready.

A typical state transition for a stack member becoming the active stack after the election is Ready > Re-Init > Ready.

A typical state transition for a stack member in version mismatch (VM) mode is Waiting > Ver Mismatch.

You can use the show switch command to identify whether the provisioned switch exists in the switch 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.

Examples

This example shows how to display summary stack information:

Device# show switch
Switch/Stack Mac Address : d4a0.2a37.4800
                                           H/W   Current

stack-mac persistent timer

To enable the persistent MAC address feature, use the stack-mac persistent timer command in global configuration mode on the switch stack or on a standalone switch. To disable the persistent MAC address feature, use the no form of this command.

stack-mac persistent timer [0 | time-value]

no stack-mac persistent timer

Syntax Description

0

(Optional) Continues using the MAC address of the current active switch after a new active switch takes over.

time-value

(Optional) Time period in minutes before the stack MAC address changes to that of the new active switch. The range is 1 to 60 minutes. When no value is entered, the default is 4 minutes. We recommend that you configure an explicit value for this command.

Command Default

Persistent MAC address is disabled. The MAC address of the stack is always that of the first active switch.

When the command is entered with no value, the default time before the MAC address changes is four minutes. We recommend that you configure an explicit value for this command.

Command Modes

Global configuration (config)

Command History

Release Modification

Cisco IOS Release 15.0(2)EX

This command was introduced.

Usage Guidelines

The MAC address of the switch stack is determined by the MAC address of the active switch. In the default state (persistent MAC address disabled), if a new switch becomes active switch, the stack MAC address changes to the MAC address of the new active switch.

When persistent MAC address is enabled, the stack MAC address does not change for a time period. During that time, if the previous active switch rejoins the stack as a stack member, the stack retains its MAC address for as long as that switch is in the stack. If the previous active switch does not rejoin the stack during the specified time period, the switch stack takes the MAC address of the new active switch as the stack MAC address.

You can set the time period to be from 0 to 60 minutes.

  • If you enter the command with no value, the default delay is 4 minutes.

  • If you enter 0 , the stack continues to use the current stack MAC address until you enter the no stack-mac persistent timer command.

  • If you enter a time delay of 1 to 60 minutes, the stack MAC address of the previous active switch is used until the configured time period expires or until you enter the no stack-mac persistent timer command.


Note

When you enter the stack-mac persistent timer command with or without keywords, a message appears warning that traffic might be lost if the old active switch MAC address appears elsewhere in the network domain. You should use this feature cautiously.

If you enter the no stack-mac persistent timer command after a switchover, before the time expires, the switch stack moves to the current stack's active switch MAC address.

If the whole stack reloads, when it comes back up, the MAC address of the active switch is the stack MAC address.

Examples

This example shows how to configure the persistent MAC address feature, with the warning messages for each configuration. It also shows how to verify the configuration:

Device(config)# stack-mac persistent timer

WARNING: Use of an explicit timer value with the command is recommended.
WARNING: Default value of 4 minutes is being used.

You can verify your settings by entering either of two privileged EXEC commands:

  • show running-config —If enabled, stack-mac persistent timer and the time in minutes appears in the output.

  • show switch —If enabled, Mac persistency wait time and the number of minutes appears in the output.

switch stack port

To disable or enable the specified stack port on the member, use the switch command in privileged EXEC mode on a stack member.

switch stack-member-number stack port port-number {disable | enable}


Note

This command is supported only on Catalyst 2960-X switches running the LAN Base image.

Syntax Description

stack-member-number

Current stack member number. The range is 1 to 8.

stack port port-number

Specifies the stack port on the member. The range is 1 to 2.

disable

Disables the specified port.

enable

Enables the specified port.

Command Default

The stack port is enabled.

Command Modes

Privileged EXEC

Command History

Release Modification

Cisco IOS Release 15.0(2)EX

This command was introduced.

Usage Guidelines

A stack is in the full-ring state when all members are connected through the stack ports and are in the ready state.

The stack is in the partial-ring state when the following occurs:

  • All members are connected through their stack ports but some are not in the ready state.
  • Some members are not connected through the stack ports.

Note

Be careful when using the switch stack-member-number stack port port-number disable command. When you disable the stack port, the stack operates at half bandwidth.


If you enter the switch stack-member-number stack port port-number disable privileged EXEC command and the stack is in the full-ring state, you can disable only one stack port. This message appears:

Enabling/disabling a stack port may cause undesired stack changes. Continue?[confirm] 

If you enter the switch stack-member-number stack port port-number disable privileged EXEC command and the stack is in the partial-ring state, you cannot disable the port. This message appears:

Disabling stack port not allowed with current stack configuration.

Examples

This example shows how to disable stack port 2 on member 4:

Switch# switch 4 stack port 2 disable

switch priority

To change the stack member priority value, use the switch priority command in global configuration mode on the active switch.

switch stack-member-number priority new-priority-value

Syntax Description

stack-member-number

Current stack member number. The range is 1 to 8.

new-priority-value

New stack member priority value. The range is 1 to 15.

Command Default

The default priority value is 1.

Command Modes

Global configuration

Command History

Release Modification

Cisco IOS Release 15.0(2)EX

This command was introduced.

Usage Guidelines

The new priority value is a factor when a new active switch is elected. When you change the priority value, the active switch is not changed immediately.

Examples

This example shows how to change the priority value of stack member 6 to 8:

Device(config)# switch 6 priority 8
Changing the Switch Priority of Switch Number 6 to 8
Do you want to continue?[confirm]

switch provision

To supply a configuration to a new switch before it joins the switch stack, use the switch provision command in global configuration mode on the active switch. To delete all configuration information that is associated with the removed switch (a stack member that has left the stack), use the no form of this command.

switch stack-member-number provision type

no switch stack-member-number provision

Syntax Description

stack-member-number

Stack member number. The range is 1 to 8.

type

Switch type of the new switch before it joins the stack.

Command Default

The switch is not provisioned.

Command Modes

Global configuration (config)

Command History

Release Modification

Cisco IOS Release 15.0(2)EX

This command was introduced.

Usage Guidelines

For type , enter the model number of a supported switch that is listed in the command-line help strings.

To avoid receiving an error message, you must remove the specified switch from the switch stack before using the no form of this command to delete a provisioned configuration.

To change the switch type, you must also remove the specified switch from the switch stack. You can change the stack member number of a provisioned switch that is physically present in the switch stack if you do not also change the switch type.

If the switch type of the provisioned switch does not match the switch type in the provisioned configuration on the stack, the switch stack applies the default configuration to the provisioned switch and adds it to the stack. The switch stack displays a message when it applies the default configuration.

Provisioned information appears in the running configuration of the switch stack. When you enter the copy running-config startup-config privileged EXEC command, the provisioned configuration is saved in the startup configuration file of the switch stack.


Caution

When you use the switch provision command, memory is allocated for the provisioned configuration. When a new switch type is configured, the previously allocated memory is not fully released. Therefore, do not use this command more than approximately 200 times, or the switch will run out of memory and unexpected behavior will result.


Examples

This example shows how to provision a switch with a stack member number of 2 for the switch stack. The show running-config command output shows the interfaces associated with the provisioned switch.

Switch(config)# switch 2 provision WS-xxxx
Switch(config)# end
Switch# show running-config | include switch 2
!
interface GigabitEthernet2/0/1
!
interface GigabitEthernet2/0/2

You also can enter the show switch user EXEC command to display the provisioning status of the switch stack.

This example shows how to delete all configuration information about stack member 5 when the switch is removed from the stack:

Switch(config)# no switch 5 provision

You can verify that the provisioned switch is added to or removed from the running configuration by entering the show running-config privileged EXEC command.

switch renumber

To change the stack member number, use the switch renumber command in global configuration mode on the active switch.

switch current-stack-member-number renumber new-stack-member-number

Syntax Description

current-stack-member-number

Current stack member number. The range is 1 to 8.

new-stack-member-number

New stack member number for the stack member. The range is 1 to 8.

Command Default

The default stack member number is 1.

Command Modes

Global configuration

Command History

Release Modification

Cisco IOS Release 15.0(2)EX

This command was introduced.

Usage Guidelines

If another stack member is already using the member number that you just specified, the active switch assigns the lowest available number when you reload the stack member.


Note

If you change the number of a stack member, and no configuration is associated with the new stack member number, that stack member loses its current configuration and resets to its default configuration.


Do not use the switch current-stack-member-number renumber new-stack-member-number command on a provisioned switch. If you do, the command is rejected.

Use the reload slot current stack member number privileged EXEC command to reload the stack member and to apply this configuration change.

Examples

This example shows how to change the member number of stack member 6 to 7:

Device(config)# switch 6 renumber 7

WARNING:Changing the switch number may result in a configuration change for that switch.
The interface configuration associated with the old switch number will remain as a provisioned configuration.

switch stack port-speed 10

To set the switch stack port speed to 10 Gbps and enable mixed stacking with one or more Catalyst 2960-S switches, use the switch stack port-speed 10 command in global configuration mode. To return to the default setting, use the no form of this command.

switch stack port-speed 10

no switch stack port-speed

Syntax Description

This command has no arguments or keywords.

Command Default

The default port speed is 20 Gbps.

Command History

Release Modification

Cisco IOS Release 15.0(2)EX

This command was introduced.

Usage Guidelines

By default, Catalyst 2960-X switches operate at a port speed of 20 Gbps while 2960-S switches have a maximum port speed of 10 Gbps. In a mixed stack of Catalyst 2960-X and Catalyst 2960-S switches, the stack must operate at the port speed of the Catalyst 2960-S switch; otherwise, the switches will not stack.

To set the port speed of the stack to 10 Gbps, use the switch stack port-speed 10 global configuration command on a Catalyst 2960-X stack member before you add a Catalyst 2960-S switch to the stack, and then reload the stack.

Examples

This example shows how to set the switch stack port speed to 10 Gbps and then reload the stack:

Switch(config)# switch stack port-speed 10
WARNING: Changing the stack speed may result in a stack speed mismatch.
Do you want to continue?[confirm]
New stack speed will be effective after next reload

Switch(config)# exit
Switch# reload
System configuration has been modified. Save? [yes/no]:

You can verify your settings by entering the show switch stack-ring speed privileged EXEC command.
