Set DHCP Server on Brocade for different VLAN's

Hello,

 

I have 2 Brocade ICX 6450-24p in stack. I set dhcp servers for different VLAN. But i don't know why only one dhcp is working. Only VLAN 100 dhcp is working. Could you help me? I checked config couple times and for me it's looks the same. I try with ip helper, but it is not for me. Because i don't want relay between different networks.

 

Thank you for help. Below i put my config.

 

Best,

Rafal

 

Current configuration:

Re: Set DHCP Server on Brocade for different VLAN's

You should check if it is actually binded and running:

 

switch#show ip dhcp-ser summ

DHCP Server Summary:

Total number of active leases: 186
Total number of deployed address-pools: 2 > Should be more in you're case
Total number of undeployed address-pools: 0
Server uptime: 02d:11h:52m:24s

 

Also check with "show ip dhcp-server address-pools" if the pools are indeed active:

 

Showing all address pool(s):


Pool Name: pool1
Time elapsed since last save: 00d:00h:02m:25s
Total number of active leases: 98
Address Pool State: active
