Cisco ISE 2.6 Performance information provided at Cisco Communities vs Installation guide at cisco.com

[Roberto.Carmona]

Hi all,

I've noticed a discrepancy about the number of max concurrent sessions that a Cisco ISE hybrid model can support. The numbers doesn't seems to match between the ISE community portal (https://community.cisco.com/t5/security-documents/ise-performance-amp-scale/ta-p/3642148) and the ISE 2.6 Installation guide (https://www.cisco.com/c/en/us/td/docs/security/ise/2-6/install_guide/b_ise_InstallationGuide26/b_ise_InstallationGuide_26_chapter_00.html)

Example:

Communities shows a max of 50k sessions in a hybrid model using 3695 servers but 100k on the Installation guide?

Any thoughts on which guide should we follow?

Thanks in advance,

It's definitely a typo on the installation guide documentation.  The community performance and scale guide is correct, 50k max on the 3695's in a standalone or hybrid deployment.  100k active sessions per 3695 if operating strictly as a PSN in a dedicated node deployment.

The section for "Hybrid-Distributed deployment" in the installation guide should reflect the same numbers as the standalone. Someone here should be able to get the docs to reflect the correct info.

Thanks Darren,

I concur with you.

Can we get a validation from Cisco? @Jason Kunst
