You probably know this one already, but I have been typing “wr t” for a long time and never stopped to look. Puts a line number at the side of the config so you can say to the person on the other end of the phone, see line 10……….

They think of everything these days. I suspect that cheap and large flash in your routers means that useful commands are now possible. I must start looking for them more often.

Thanks, very useful command – never noticed it before
Hi,
Yes really useful, thanks again
“Cheap and large flash” means that you have heaps of weird code in IOS, including Tcl, XML, VoiceXML, maybe Perl is coming along …
I wish that Cisco would realize that flash is cheap and could be larger. I can’t believe how small of flash chips still come standard compared the to the larger and larger IOS images. Of course it would also be nice to run uncompressed IOS images like in dynamips. They load much faster.
