Chapter 11 Configuring Cisco NSF with SSO Supervisor Engine Redundancy
Configuring NSF with SSO Supervisor Engine Redundancy
Switch# show isis nsf
NSF is ENABLED, mode 'cisco'
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 RP. In this
example, note the presence of “NSF restart enabled”:
Switch# 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
Step 3 If the NSF configuration is set to ietf, enter 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 the
networking device:
Switch# show isis nsf
NSF is ENABLED, mode IETF
