Hi, am running V 6.3.5 and have a total of 24 maximum interfaces on my Pix, and are currently using 15 of them. If I upgrade to V7, does that maximum number increase ???? I have looked for doco on the maximum under V7 but cannot locate anything.
I have an unrestricted license, and 24 is currently the limit of int's, of course I do not have that many physical. The max interfaces is a representation of total logical and physical interfaces allowed.
I have upgraded a 515 and got a larger count on max interfaces, so am sure it does, just cannot find doco :(
However the SPNA book also states: "The maximum number of logical interfaces that you can use is equal to the total number of interfaces minus the total number of physical interfaces that you currently have configured", which I think is ambiguous at best.
I'm pretty sure it means total number of interfaces minus those interfaces configured with addresses without sub-interfaces.
However, in regards to your initial question, I thought that you wouldnt get an increase in interfaces by default, however I could be wrong. As you said, there isnt much documentation on this question.
