ISE & TCACS+

Hi,

if I use ISE VM exclusively as a TACACS+ server, how should the VM sizing be done?

Thx

from the guide:

 

Different Types of Cisco ISE Deployment

Small Deployment
All ISE personas (PAN + MnT + PSN + pxGrid) on the same appliance or VM instances.

 

from install guide:

https://www.cisco.com/c/en/us/td/docs/security/ise/3-1/install_guide/b_ise_InstallationGuide31.pdf
Table 4: OVA Template Reservation
OVA Template Type:
- Number of CPUs: 16
- CPU Reservation (In MHz): 16,000
- Memory (In GB): 32

 

Should i allocate 16 CPU and 32 GByte of RAM as a full installation (all ISE personas) even if I only use TACACS?

Are all these resources needed for tacacs functionality only?

 

Look at the model : TACACS+ Performance

 

how many devices , TACACS request

 

that spec you mentioned should work.

400 devices, the "Small Deployment" sizing seems oversized to me

ISE have only small / medium and large

 

If this is Only for device Access, you like to save money too.. if i were you i use Freeradius ( simple Linux box no License cost)
