i would like to get some idea for IOS IPS signature update.
example currently the router fresh install using IOS-S416-CLI.pkg, IOS category ios_ips in advanced mode, with retired false.
Just wonder what if next time download and loading with latest patch of the IOS-SXXX-CLI.pkg into the machine, what will effect on the current compiled signature?
will it just loaded in incremental form? (meaning is it the signature in latest patch will added as new enable signature), then what about the signature previously being modified and save one, any effect on it? (like re-write my previous save signature)
with the new patch install, would it also effect on the router DRAM and flash size? (my router with 384 mb DRAM and 128mb flash)
