Clients not getting DHCP on certain AP
We curretly have a setup with 120 AP's R310 being managed by a SZ100. Network is divided into subnets ,each subnet having a different DHCP pool and VLAN.
On one particular subnet ( comprised of 24 AP) I have a strange problem with one of the AP's in the sense that clients associated to the AP cannot get an IP address from the DHCP
While troubleshooting the problem with the Troubleshot tool inside SZ we have seen that client correctly authenticates and associates with that articular AP and starts sending DHCP Discover messages but gets no answer from the DHCP server.
SZ100, fimware version 22.214.171.124.227
All other AP's and clients within that subnet work flawlessly ( all clients getting IP addresses from the DHCP server)
DHCP server has still enough leases
SNR and RSSI for clients look ok
That specific AP is also flagged with 'Connection failures' main reason being DHCP
Can someone give a hint where to go on with teh investigation ?
