Enabling High Availability Features

RP is ACTIVE, standby ready, bulk sync complete

NSF interval timer expired (NSF restart enabled)

Checkpointing enabled, no errors

Local state:ACTIVE, Peer state:STANDBY HOT, Mode:SSO

The following display shows sample output for the Cisco configuration on the standby RSP. In thisexample, note the presence of “NSF restart enabled”:

Router# show isis nsf

NSF enabled, mode 'cisco'

RP is STANDBY, chkpt msg receive count:ADJ 2, LSP 7

NSF interval timer notification received (NSF restart enabled)

Checkpointing enabled, no errors

Local state:STANDBY HOT, Peer state:ACTIVE, Mode:SSO

Step3 If the NSF configuration is set toietf, use the show isis nsf command to verify that NSF is enabled on

the device. The following display shows sample output for the IETF IS-IS configuration on thenetworking device:

Router# show isis nsf

NSF is ENABLED, mode IETF

Figure9 Software Error ProtectionBacking Up with an Older Software Version, Part I Figure10 Software Error ProtectionBacking Up with an Older Software Version, Part II Next,we copy the rsp-pv-mz.120-23.S image to the active and the standby RSPs, as shown in Figure 10. Last,we delete the rsp-pv-mz.120-22.3.S1 image from the standby RSP4/4+ card, as shown in Figure 11: Figure11 Software Error ProtectionBacking Up with an Older Software Version, Part III Complete the following steps to configure software error protection for this sample scenario: 0 on the active and standby RSPs: and standby RSPs: Setting Environment Variables on the Active and the Standby RSPs Manually Setting Environment Variables on the Standby RSP Automatically Setting Environment Variables on the Standby RSP Monitoring and Maintaining HSA Operation Enabling High Availability Features High Availability Feature Overview Page Hardware and Software Prerequisites Installation Procedures Enabling the Router Copying an Image onto an RSP Page Setting the Config-Register Boot Variable Configuring RPR and RPR+ Page Verifying RPR and RPR+ Use the show redundancycommand to verify that RPR or RPR+ is enabled: Configuring RPR and RPR+ Example Configuring a Stateful Switchover (SSO) Configuring Frame Relay Autosynchronization LMI Sequence Numbers Verifying SSO Note The output of these commands will vary based on your device configuration and system site requirements.
