MS355-24X2 Not Taking Configuration

[Cryo-Help]

After making changes on the MS355-24X2 Vlan to enable DHCP for the AP units, it appears the setting don't take affect.  Does the switch need to be rebooted after making some changes?

[PhilipDAth]

No.  The configuration usually kicks in after about 1 minute.

Are the APs configure to use a specific VLAN for their management, on the AP side - or are they just using the native VLAN?

On the switch port, if the native VLAN is being used - is it set to the correct VLAN?

[Cryo-Help]

Yes, we have:

101 manage-transit

102 Wired Network

103 Meraki AP's for Wi-Fi

[PhilipDAth]

So you have DHCP configured in VLAN103, and the switch port set to be a trunk port with a native VLAN of 103?

[Cryo-Help]

That is correct.  We believe we figured it out, on Vlan 103, the DHCP Option Code was set to 3, we changed it to 15 and will have to test in a couple of hours with our overseas office.

[Cryo-Help]

Confirmed, that fixed the issue.
