Firepower Memory Utilization

ashutosh.joshi1 — Tue, 12 Mar 2019 13:28:24 GMT

Hello All,

I am using Firepower 6.2.0, I want to increase the RAM for it.

How we can do. Firepower is configured in FMC

You cannot change the allocated RAM for a Firepower module. It is fixed by the OS.

hi Marvin,

Was trying to find a way of bringing a post to your attention so forgive me for appearing to hijack this thread!

I have two questions:

will an Firepower appliance (8150) allocate resources based on the security zones (mapped to interfaces)? Or does it do it some other way
If a sensor (in passive mode) is receiving two halves of network communication on separate interfaces on that same sensor, will it automatically reconcile them into full conversations for the purposes of inspection? Would those interfaces need to be in the same security zone as well? We have some asymmetric routing issues we are trying to cope with but the sensor in question is receiving the full session information albeit on separate interfaces

any help would be greatly appreciated

1. I don't know.

2. I don't think it knows to stitch the pieces together in that scenario but I'm not 100% sure.
