Process/Memory consumption for IOS Enhanced software MTP

Hi,

 

I'd like to know how much process/memory will be utilized if I configure the IOS Enhanced Software MTP on Cisco 2921 Router.

 

Here is the gateway details.

Cisco CISCO2921/K9 (revision 1.0) with 2506752K/114688K bytes of memory.
Processor board ID FGL175010JB
3 Gigabit Ethernet interfaces
1 Serial(sync/async) interface
1 terminal line
1 Virtual Private Network (VPN) Module
DRAM configuration is 64 bits wide with parity enabled.
255K bytes of non-volatile configuration memory.
2048256K bytes of ATA System CompactFlash 0 (Read/Write)

IOS Version 15.3(3)M

 

When the MTP is invoked & being used, will it affect the call routing performance of gateway?

 

The maximum session will vary depends on the Platform & IOS?

There is no straight answer

There is no straight answer to your question as it all depends on your current config, RAM and CPU usage, and there are far too many variables to give a yes/no answer.

Yes, the maximum sessions depend on platform and memory, and they're all based on the assumption that the ISR, other than basic networking, will be ONLY doing IOS MTP and keeping CPU below 75%

Obviously if that same ISR has TDM, AAA, H.323, SIP, security, etc resources will be consumed and so on, so the resources for IOS MTP will decrease, and so the maximum number of sessions.

The only way to answer your question is:

A) Hire Cisco Advanced Services so they can lab this up for you and give you the results

B) Do the above yourself.
