.SH "CAVEATS"
Cisco IOS offers a DHCP server that maintains a text database which can be
stored remotely or on local storage.
If stored locally, the file changes constantly and causes constant diffs
from rancid.
If this file's name ('ip dhcp database') matches the regex
dhcp_[^[:space:].]\.txt, it will be filtered.
.Pp
For Catalyst switches running CatOS, type
.B cat5,
the prompt must end with '>'.
.BR clogin (1)
looks for '>' to determine when a login is successful.  For example:
.sp
.in +1i
.nf
cat5k>
cat5k> enable
Password: 
cat5k> (enable) 
.fi
.in -1i
.PP
.B rancid
works on Cisco Catalyst 1900 series switches that are running Enterprise
Edition software.  This software provides a menu at connection time that
allows a command line interface to be used by entering 'K' at the prompt.
