Chapter 6 Configuring Supervisor Engine Redundancy Using RPR and SSO

Configuring Supervisor Engine Redundancy

Redundancy Mode (Operational) = Stateful Switchover

Redundancy Mode (Configured) = Stateful Switchover

Split Mode = Disabled

Manual Swact = Enabled

Communications = Up

client count = 21

client_notification_TMR = 240000 milliseconds

keep_alive TMR = 9000 milliseconds

keep_alive count = 0

keep_alive threshold = 18

RF debug mask = 0x0

Switch#

This example shows how to change the system configuration from RPR to SSO mode:

Switch(config)# redundancy

Switch(config-red)# mode

Switch(config-red)# mode sso

Changing to sso mode will reset the standby. Do you want to continue?[confirm]

Switch(config-red)# end

Switch#

*Aug 1 13:11:16: %C4K_REDUNDANCY-3-COMMUNICATION: Communication with the peer Supervisor

has been lost

*Aug 1 13:11:16: %C4K_REDUNDANCY-3-SIMPLEX_MODE: The peer Supervisor has been lost

This example shows how to change the system configuration from SSO to RPR mode:

Switch(config)# redundancy

Switch(config-red)# mode rpr

Changing to rpr mode will reset the standby. Do you want to continue?[confirm]

Switch(config-red)# end

*Aug 1 13:11:16: %C4K_REDUNDANCY-3-COMMUNICATION: Communication with the peer Supervisor

has been lost

*Aug 1 13:11:16: %C4K_REDUNDANCY-3-SIMPLEX_MODE: The peer Supervisor has been lost

Synchronizing the Supervisor Engine Configurations

To manually synchronize the configurations used by the two supervisor engines, perform this task on the
active supervisor engine:

Command

Purpose

Step 1

Switch(config)# redundancy

Enters redundancy configuration mode.

Step 2

Switch(config-red)#

main-cpu

Enters main-cpu configuration submode.

Step 3

Switch(config-r-mc)# auto-sync {startup-config |

config-register

| bootvar | standard}

Synchronizes the configuration elements.

Step 4

Switch(config-r-mc)# end

Returns to privileged EXEC mode.

Step 5

Switch# copy running-config startup-config

Synchronizes the running configuration in dynamic
random-access memory (DRAM) to the startup
configuration file in NVRAM.

Note

This step is not required to synchronize the
running configuration file in (DRAM).
