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

stack unit 1

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 :)

  • Do you have enough public IP addresses for your clients to pull from or are you restricted to private IP addresses?

Reset to default

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.
