You should always set the switch number and priority of each switch prior to that something goes wrong, so you need to be prepared to reboot the entire stack​. the stack from bundle mode to install mode, which is the Cisco recommended​.

High level Cisco Catalyst 3850 switch stack

From the redundancy main configuration submode, use the standby console enable command to enable the standby switch. To display information that is related to the stack member or the switch stack, use the show switch command in EXEC mode. To display platform-dependent switch-stack information, use the show platform stack-manager command in privileged EXEC mode. If the previous active switch rejoins the stack during that time period, the stack retains its MAC address for as long as the switch that has that MAC address is in the stack. If you ignore the mismatched commands, the out-of-synchronization configuration on the active switch and the standby switch still exists. To display all the mismatched commands, use the show redundancy config-sync failures mcl command. If you do not change the stack MAC address, Layer 3 interface flapping does not occur. The table that follows describes the fields in the display. To enable access to the standby console switch, use the standby console enable command in redundancy main configuration submode. The undebug platform stack-manager command is the same as the no debug platform stack-manager command. 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. The redundant switch becomes the new active switch that runs the Cisco IOS image, and the modules are reset to their default settings. The cable might not be connected, or the link might be unreliable. Whether the stack cable is connected and functional. To enter redundancy configuration mode, use the redundancy command in global configuration mode. This action allows the standby switch to boot in a standby hot SSO state when it reloads. Use the exit command to exit redundancy configuration mode. The range is 1 to 60 minutes. This return code indicates whether or not the command successfully executes. Use the stack-mac update force command to force the stack MAC address to change to the MAC address of the new active switch. By default, the stack MAC address will always be the MAC address of the first active switch, even if a new active switch takes over. If you use this command on a switch that is in a partial ring stack, the following warning message appears:. If a PRC error occurs at the standby switch either during bulk synchronization or line-by-line LBL synchronization, the standby switch is reset. The range is 1 to 9. Do not use this command unless your technical support representative asks you to do so. To disable access to the standby console switch, use the no form of this command. To trace the control and provisioning of wireless access point high availability, use the set trace capwap ap ha privileged EXEC command. To display best effort method BEM errors, use the show redundancy config-sync failures bem command. It is not configurable. To specify that the standby switch is not reloaded if a parser return code PRC failure occurs, use the no form of this command. To display all PRC failures, use the show redundancy config-sync failures prc command. Enter additional keywords to display all clients or counters in the specified slave. The same behavior occurs when you enter the stack-mac persistent timer command or the stack-mac persistent timer 0 command. Use the no command to disable redundancy. Use this command only when you are working directly with your technical support representative while troubleshooting a problem. You can verify your settings by entering the show running-config privileged EXEC command. If the command syntax check in the running configuration of the active switch fails while the standby switch is booting, use the redundancy config-sync mismatched-commands command to display the Mismatched Command List MCL on the active switch and to reboot the standby switch. Optional Displays information about the redundancy facility state, such as disabled, initialization, standby or active. Optional The name of the redundancy facility slave to display specific information for. To display wireless mobility high availability, use the show trace messages mobility ha privileged EXEC command. You can verify your settings by entering the show switch privileged EXEC command. If you ignore the mismatched commands, the out-of-sync configuration at the active switch and the standby switch still exists. To display a configuration synchronization failure or the ignored mismatched command list MCL , if any, use the show redundancy config-sync command in EXEC mode. Optional Continues using the MAC address of the current active switch indefinitely, even after a new active switch takes over. This example shows how to enter the redundancy main configuration submode and enable the standby switch:. To enter the redundancy main configuration submode and enable the standby switch, use the main-cpu command in redundancy configuration mode. The redundancy configuration mode is used to enter the main CPU submode, which is used to enable the standby switch. Use the redundancy reload shelf command to reboot all the switches in the stack. You can use the show switch command to identify whether the provisioned switch exists in the switch stack. If SSO mode cannot be established between the active and standby switches because of an incompatibility in the configuration file, a mismatched command list MCL is generated at the active switch and a reload into route processor redundancy RPR mode is forced for the standby switch. When two versions of Cisco IOS images are involved, the command sets supported by two images might differ. If enabled, stack-mac persistent timer is shown in the output. Optional Displays a reverse log of past status and related information for the redundancy facility. The standby switch executes the command and sends the PRC back to the active switch. The active switch maintains the PRC after executing a command. The MAC address of the stack is always that of the first active switch. To debug the wireless mobility high availability in the switch , use the set trace mobility ha privileged EXEC command.

To enable debugging of the stack manager software, use the debug platform stack-manager command in privileged EXEC mode. Each command sets a return code in the action function that implements the command.

This command is used to collect and review https://89099547875.ru/best/silver-sevens-all-you-can-eat-crab-legs.html data about the standby console.

To set the redundancy mode to stateful switchover SSO , use the mode sso command in redundancy configuration mode. This example shows how to specify that the standby switch is not reloaded if a parser return code PRC failure occurs during configuration synchronization:. You can clear the peer image from the incompatible list with the redundancy config-sync ignore mismatched-commands EXEC command while the peer is in a standby cold RPR state. If you use the redundancy force-switchover command on the active switch, the switchports on the active switch to go down. If the switch with this foreign MAC address joins another stack as the active switch, two stacks will have the same stack MAC address. The mode sso command can be entered only from within redundancy configuration mode. Optional Time period in minutes before the stack MAC address changes to that of the new active switch. This example shows how to revalidate the mismatched command list with the modified configuration:. To disable debugging, use the no form of this command. Accesses the diagnostic shell of a specific stack member or the Cisco IOS prompt of the standby Switch. To allow the standby switch to join the stack if a configuration mismatch occurs between the active and standby switches, use the redundancy config-sync mismatched-commands command in privileged EXEC mode. When you access the diagnostic shell of a stack member, diag is appended to the system prompt. Use the show platform stack-manager command to collect data and statistics for the switch stack. If the switch with the same MAC address as the stack MAC address is currently a member of the stack, the stack-mac update force command has no effect. To enter the main CPU submode, use the main-cpu command while in redundancy configuration mode. To force a switchover from the active switch to the standby switch, use the redundancy force-switchover command in privileged EXEC mode on a switch stack. If there is more than one switch in the switch stack, and you enter the reload slot stack-member-number command, you are not prompted to save the configuration. Use the redundancy force-switchover command to manually switch over to the redundant switch. Optional Stack member number to access from the active switch. If the syntax check for the command fails on the standby switch during a bulk synchronization, the command is moved into the MCL and the standby switch is reset. You must use the stack-mac update force command to resolve the conflict. Optional Displays a configuration synchronization failure or the ignored mismatched command list MCL. To reload the stack member and to apply a configuration change, use the reload command in privileged EXEC mode. RPR mode is supported on Catalyst switches as a fallback in case of errors. This example shows the output for the show switch stack-ports summary command. The show running-config and the show startup-config privileged EXEC commands do not provide this information. For more information, see show redundancy config-sync. If any of those mismatched commands are executed on the active switch, the standby switch might not recognize those commands, which causes a configuration mismatch condition. To disable the persistent MAC address feature, use the no form of this command. If you disable redundancy and then reenable it, the switch returns to default redundancy settings. If the switch cannot detect the cable length, the value is no cable. There may or may not be a neighbor connected on the other end. From the main CPU submode, use the standby console enable command to enable the standby switch. Persistent MAC address is disabled. To display all mismatched commands, use the show redundancy config-sync failures mcl command. To display redundancy facility information, use the show redundancy command in privileged EXEC mode. When you enter the stack-mac persistent timer command with a time-value , the stack MAC address will change to that of the new active switch after the period of time that you entered whenever a new switch becomes the active switch. To reload the standby switch if a parser return code PRC failure occurs during configuration synchronization, use the policy config-sync reload command in redundancy configuration mode. To force a reload of one or all of the switches in the stack, use the redundancy reload command in privileged EXEC mode.
