NSP Redundancy
Primary (NSP A) ehsa state:SANTA_EHSA_PRIMARY
Secondary (NSP B) ehsa state:SANTA_EHSA_SECONDARY
EHSA pins:
peer present = 1
peer state = SANTA_EHSA_SECONDARY
crash status:this-nsp=NO_CRASH(0x1) peer-nsp=NO_CRASH(0x1)
EHSA related MAC addresses:
this bpe mac-addr = 0000.0c00.0003
peer bpe mac-addr = 0000.0c00.0004

Synchronizing Redundant NSPs
To ensure that the configuration is consistent between redundant NSPs or NRPs, you can configure
automatic synchronization between the two devices. You have the option of synchronizing just the
startup configuration, the boot variables, the configuration register, or all three configurations
(standard). When configuration is complete, you can disable autoconfiguration using the no command.
To automatically synchronize the configurations between redundant NSPs, complete the following steps
beginning in global configuration mode:
Boot variables are ROM monitor (ROMMON) environment variables used to control the booting
process. The configuration register, stored in NVRAM, contains startup time parameters for the system.
For more information about the booting process, see the Cisco IOS Configuration Fundamentals
Configuration Guide.
Example
In the following example, the configuration is synchronized between redundant NSPs:
!
redundancy
main-cpu
auto-sync standard
!
Command Purpose
Step1
Switch(config)# redundancy
Enters redundancy configuration mode.
Step2
Switch(config-r)# main-cpu
Enters main-cpu configuration mode.
Step3
Switch(config-r-mc)# auto-sync [standard |
bootvar | config-register | startup-config]
Synchronizes the configuration between redundant NSPs.
