If I want to use NBAR, do I have to load any additional modules from flash? According to documentation, NBAR is available with IOS Release 12.0(5)XE2. Are the additional modules that need to be loaded from flash "just" to extend the functionality of NBAR.. IE.
packet description language module (PDLM)
My question is this: If I have IOS Release 12.0(5)XE2, can I immediately start using NBAR, or do I have to load additional modules?
