Clients can't get IP addresses from DHCP server on one of the WLANs. We have several WLANs and all work except one. APs are 7532 and 2 NX5500 controllers. DHCP server is on Huawei Firewall. All WLANs on different VLANs. APs connect to controllers via management vlan. Controllers connected to the core switches via trunks that allow all vlans. Same as the firewall.
I can ping gateway of the vlan that doesn't work from controllers and APs.
