DHCP with Brocade

brocadedhcp

I have the following config on a brocade icx with the premium license for L3 features:

stack unit 1
  module 1 icx6450-24p-poe-port-management-module
  module 2 icx6450-sfp-plus-4port-40g-module

I have a PC plugged into a random port 17 but it's not able to get a lease from this switch.

The logs show this when the PC tries to renew its ip:

    0d03h52m09s:A:DHCPS: unable to find an address pool for rx port 10, dropping DHCPOFFER message
0d03h52m09s:A:DHCPS: Exhausts all allocation methods, no address pool found from received port 10 
0d03h51m53s:A:DHCPS: unable to find an address pool for rx port 10, dropping DHCPOFFER message
0d03h51m53s:A:DHCPS: Exhausts all allocation methods, no address pool found from received port 10

Anyone know how I can get this to work properly and so that once the PC's get a lease, they will be able to browse the internet, etc?

Thanks

UPDATE

I made the following changes and now the PC is able to get a lease.

added a new vlan and put port 17 into it along with creating a new ve instance

 vlan 20 by port
     untagged ethe 1/1/17 
     router-interface ve 20
    spanning-tree 802-1w


interface ve 20
 ip address 10.10.10.1 255.255.255.0

Now I got this:

0d04h19m04s:I:DHCPS: sending ACK message to client 10.10.10.11    
0d04h19m04s:I:DHCPS: verified client requested address 10.10.10.11 in lease binding, updating entry
0d04h19m04s:I:DHCPS: No ARP-PING reply from client 10.10.10.11

Bindings from all pools:
    IP Address    Client-ID/        Lease expiration Type
                  Hardware address

   10.10.10.11    0013.72d1.c847   000d:23h:49m:43s   Automatic

Now just need to make sure I can browse the internet from the PC tomorrow and I'm all good!

Even though I figured it out on my own…hope this helps someone and thanks everyone 🙂

Best Answer

interface ve 10
 ip address x.x.x.140 255.255.255.248

ip dhcp-server pool noc
 network 10.10.10.0 255.255.255.0

It doesn't work because ve 10 (the L3 interface) isn't within the noc dhcp pool (10.10.10.0/24) Your updated ve 20 is, but unless you have something upstream of here doing NAT, there won't be any internet access.
