An example of how configuration checking may force the system into RPR mode is provided in the following output:

Switch 2 has the following configs that mismatch with Switch 1:
Interface TenGigabitEthernet1/5/4 shutdown
*Jun 29 14:08:22.210: SW2_SP: VS_PARSE_DBG_ERR: vs_redun_send_check_vs_config:

config check on rp not ok
*Jun 29 14:08:22.218: %PFREDUN-SW2_SP-6-ACTIVE: Standby initializing for RPR mode
This output shows that the configuration consistency check failed because of a mismatch in the VSL configuration
between Switch 1 and Switch 2. In this case, Switch 2 has an extra “shutdown” statement under one of its VSL
between Switch 1 and Switch 2. In this case, Switch 2 has an extra “shutdown” statement under one of its VSL
members, whereas Switch 1 does not, forcing the standby virtual switch (in this case, Switch 1) into RPR mode.
In order to recover from this situation, make the necessary changes to the configuration, save the configuration,
and reload the standby chassis:
vss#conf t
Enter configuration commands, one per line. End with CNTL/Z.
vss(config)#int te1/5/4
vss(config-if)#no shut
vss(config-if)#^Z
vss#wr

Upon reload of Switch 1, configurations are now synchronized and both switches can enter into NSF/SSO mode:
