BFD timers recommendation with MACsec

[hardeepkumar]

Hello All

In the Cisco documentation, Topic: Recommendations for MACsec Encryption

I came to know that recommended BFD timer values are 750 milliseconds for 10Gbps ports and 1.25 seconds for any port with speed above 10Gbps.

my query is :

- Why such high values are recommended, doesn't these impact the convergence time ?

- If I use lower values , for example - 100ms multiplier 3 - then what could be the difference in behavior.

This sounds like a switching question and not an ISE / NAC questions but you didn't include a link to the Cisco documentation you are referring to. If so, you should move this question to Cisco Community > Technology and Support > Networking > Switching
