DCHP snooping requirement on 5760 controller

jlarriega — Mon, 05 Jul 2021 08:25:55 GMT

To All;

I like to know if DHCP snooping is a requirement in a centralized deployment where there is one 5760 and 5508 for guest access.

In "Converged-Access-White Paper" page 31 states DHCP snooping is required in the Converged Access deployment and I am not clear if this requirement is for deployments with 3850 switches which is not my case.

Thanks;

Enabling it on your 5760 won

Enabling it on your 5760 won't harm. That facilitate DHCP clients will get IP addresses much quicker compare to when it is disabled (having said that I haven't test it by myself).

You can do a test with & without & see if there is considerable differences.

Thank you Rasika;

The problem is that APs are being installed now by a vendor that has been contracted to installed and Hard code the IP addresses on all the APs at a building (7 Floors). I've been trying to talk them out of hard coding the IP addresses. I like to know if DHCP and DCHP snooping are REQUIREMENT for roaming when the APs are associated to a 5760 instead of 3850.

Thanks;

I am not referring to AP IP

I am not referring to AP IP addresses, but client IP (Yes it is a good practice to keep AP IP in DHCP so it is more flexible from operation point of view).

No, it is not specific to 5760 instead of 3850. It is a best practice configuration in Converged Access where enabling DHCP snooping on wireless vlans help to build different client database tables & helping wireless client to get IP addresses much quicker.
