SG300 DHCP server are not issuing IP addresess *Please help!*


Guys,

I have been trying to figure this our for hours and I know it must be something simple. I have SG300-52p switch. I have configured my DHCP pool for one vlan, enabled DHCP server and nothing is getting issued IP's. I want to issue IP's on Vlan 20.

 

Below is my config:

config-file-header
ZEUSSW1
v1.3.5.58 / R750_NIK_1_35_647_358
CLI v1.0
set system mode router 

file SSD indicator encrypted
@
ssd-control-start
ssd config
ssd file passphrase control unrestricted
no ssd file integrity control

Hi Blabadie,

Please run wireshark on the DHCP client, also you may want to try to change subnet mask to class C.

The devices in question are IP cameras, so I will connect a PC on another port and assign it to the same vlan and run wireshark. Changing the subnet is a good idea, I might try that as well.
