Why does my switch say it is syncing startup config to the standby router?

Question:

I got the following message.

Nov 11 14:39:04: %PFINIT-SP-5-CONFIG_SYNC: Sync’ing the startup configuration to the standby Router

Here is a few log entries before it happened.

Solution:

No, Dragon, good news. It means that the startup config on your active sup is syncing with the standby sup so if your active sup goes down, your standby has a current config.
