DHCP server created on switch can't bind IP address

[klui]

Hi,

I have an ICX6610 that I wanted to test some subnets on an SRX 240 firewall. On my SRX I have an interface that's configured as a DHCP client. If I connect a cord between that port and another switch that has DHCP from an SSG firewall, I get an IP bound.

But if I connect it to a port on the 6610 I get the offer but there is no binding on the SRX. The 6610 though sees it as bound. After around a minute or so the SRX port returns to INIT state.

How can I investigate DHCP issues on the 6610?

Here's my config:

vlan 20 by port
 untagged ethe 1/1/2
 router-interface ve 20
!

ip dhcp-server enable
!
ip dhcp-server pool dhcp20
 dhcp-default-router 192.168.20.254
 excluded-address 192.168.20.100 192.168.20.254
 lease 1 0 0
 network 192.168.20.0 255.255.255.0
 deploy
!

interface ve 20
 ip address 192.168.20.254 255.255.255.0
!

SSH@ICX6610-48P Router#show ip dhcp-server binding
Bindings from all pools:
        IP Address    Client-ID/        Lease expiration Type
                      Hardware address

      192.168.20.1    288a.1c40.e8cd   000d:23h:59m:37s   Automatic

I have no VLANs configured on the SSG/SRX port. I thought I could define a VLAN and untag the port on the ICX and it should work. The port works with a notebook running Windows. Is there anything more I must add to the configuration?


Thanks!
