On Cisco Nexus 9508 What is the Maximum VPN Throuhput?

We have ten gigabit interfaces. How much tunneled traffic would the device be able to push?

Hi Amigan,

How are you looking at a VPN on the switch? VPNs start/end at the Gateways, which is why mfgs publish different throughputs specifically for VPN and encrypted traffic on Firewalls and not Switches. If you are talking about encrypted traffic on a switch that will be the same throughput rates published by the mfg (https://www.cisco.com/c/en/us/products/collateral/switches/nexus-9000-series-switches/solution-brief-c22-730049.html) as encryption processing only occurs at the source/destination side. Your switch can push a ton of traffic; see under Table 1 in my link above. Here is a performance testing report for more details: https://www.cisco.com/c/dam/en/us/products/collateral/switches/nexus-9000-series-switches/cisco-report-nexus-9508.pdf

Let me know if you have any other questions!

@Blue Street: The 9508 is a core device that does both switching and routing. So we have BGP and OSPF as the routing protocols. Are you saying that VPN is just not a feature on the sup of a 9508? No IPsec, no GRE?

Nexus 9508 does not support ipsec vpn tunnel termination.
Or do you mean DCI (data centre interconnect) such as OTV < (BGP) Ethernet VPN (EVPN) >???

The bottom-line is that if your device could do this they would most assuredly show it with the traffic bandwidth specs i shared above. But because your device cannot terminated encrypted traffic, but rather disseminate it, the rates I shared apply to all traffic; encrypted or not.
