Hello,
We have noticed a high CPU/Memory usage for both vWLC version 8.1.111.0 and our MS DHCP Server
vWLC is configured with DHCP Proxy
When sniffing the traffic on DHCP server I noticed that WLC's Wireless Interfaces are constantly sending DHCP Discover for clients even if they already got IP address from DHCP.
So it looks like this:
DHCP Discover from WLC
DHCP Offer from DHCP
DHCP Request from WLC
DHCP ACK from WLC
And then the proccess starts over again for the same client (MAC) with Discover(WLC) - Offer(DHCP) messages. Sometimes I notice DHCP NAK messages for the client, which previously received an IP
Lease time is set to 1 hour.
This doesnt happen to wired clients.
MS DHCP server is clustered with another MS DHCP server acting as a secondary.
Do you have any thoughts on this?
Thank you
