Hi bros,
Our customer is asking us on the ISE bwd requirements for with some specific cases below:
I found that KB: https://community.cisco.com/t5/security-documents/ise-latency-and-bandwidth-calculators/ta-p/3641112 but it does not cover all the qns.
Highly appreciate for your advise. Thanks in advance.

The link with the bandwidth calculator that you listed is the only validated calculator out there. With that said, I have done several successful ISE deployments where the endpoints were pretty far away with 300+ ms RTT. The most important part here is to ensure that there is enough bandwidth in the pipe so you don't end up starving the dot1x traffic. Otherwise, you will run into nasty issues with DHCP timing out, dot1x timing out, etc. Thus, if the links are small, then they will either need to upgrade them or have a very well deployed QoS.
Lastly, several ISE versions ago, the documentations used to list bandwidth requirements. Those are no longer included in the docs but I had saved them for future reference:
Description |
Bandwidth |
Minimum bandwidth between monitoring and policy service |
1 Mbps |
Minimum bandwidth between monitoring and admin |
256 Kbps |
Minimum bandwidth between client and policy service with posture |
125 bps per endpoint |
Minimum bandwidth between monitoring and monitoring (redundant) |
256 Kbps |
Minimum bandwidth between admin and policy service (redundant admin) |
256 Kbps |
I hope this helps!
Thank you for rating helpful posts!

HI Jason, please do you have a calculator for ISe 3.0 bandwidth?
