What changes have been done since last “wr mem”? Or more like; what differences are there between running-config and startup-config?
Use the archive-feature!
r2#sh arch conf diff nvram:startup-config system:running-config
Contextual config diffs:
line vty 0 4
+transport input all
+transport output all
line vty 0 4
-transport input telnet
-transport output all
Wanna make periodic backups of the router config to local flash?
Use the archive-feature!
r1#sh run | sect archive
archive
log config
record rc
logging enable
hidekeys
path flash:backup
time-period 86400
r1#
You can of course archive the config to an external server instead…
r1(config)#archive
r1(config-archive)#path ?
