Hi Ryan, If I'm understanding what you're trying to do, you could script around our rather unsophisticated 'sgrep' (stanza grep) tool combined with scripting around rancid & rcs to do what I think you are looking for. http://net.doit.wisc.edu/~dwcarder/scripts/sgrep sgrep can dump out a "stanza" of ios-like config, then you can rcsdiff that to your master, per 'chunk' of config. ex: > sgrep -s "vty" r-cssc-b280c-1-core.conf Found stanza in r-cssc-b280c-1-core.conf size:9 line vty 0 4 access-class G-A-AdminAccess in exec-timeout 30 0 ipv6 access-class G-A-v6AdminAccess in line vty 5 24 access-class G-A-AdminAccess in exec-timeout 30 0 ipv6 access-class G-A-v6AdminAccess in ! See the -s and -e options for our sgrep. Add 'xargs -P' around your glue, and I think you'd be in luck. If you were building configs around this model, you could use m4. Dale
