"Invisible" DHCP Pool - PowerSwitch S4148F-ON
Hi folks, any thoughts would be appreciated here.
Our core is a pair of PowerSwitch S4148F-ONs (Core01 and Core02 - using VRRP - both running 10.5.0.9.766), and these serve DHCP to some of our less important VLANs. Due to some project work, I needed to remove DHCP from one of these VLANs.
Although the DHCP pool on our core is seemingly deleted/disabled (no longer shows in running-config), it is still issuing DHCP addresses. I have confirmed with Wireshark that the DHCP ACKs are indeed coming back from the IP of Core01. Both cores have had the pool removed and show no evidence of these pools existing. Both configs of both cores have been saved.
The config and steps I followed are as thus:
Example config:
Pool VLAN_010
network 192.168.10.0/24
default-router 192.168.10.1
dns-server 8.8.8.8 8.8.4.4
range 192.168.10.10 192.168.10.220
The commands ran to "remove":
core01(config)#ip DHCP server
(config-dhcp)#no pool VLAN_010
Thanks in advance.

JoePTI,
From the looks of it, you will likely have to restart the DHCP for it to take effect, so you may have to do no ip dhcp server to turn it off fully, or you may need to restart the switch. On a side note though, you should ensure DHCP server is only enabled on 1 switch as running two I don't believe would be supported.
Let me know if this helps.
