Hi

I am trying to configure an SRX110H2-VA (12.1X44-D15.5) as a dhcp server using dhcp-local-server.

The SRX is also setup as a DHCP client from the ISP at fe-0/0/0 and this works fine.

When I plug in some devices in fe-0/0/[1-7] such as a laptop, they are assigned an IP address fine, but other devices such as an ethernet EFTPOS machine are not. The client is stuck at SELECTING.

    services {
        ssh;
        telnet;
        xnm-clear-text;
        dhcp-local-server {
            traceoptions {
                file dhcp.dbg;
                flag all;
            }
            group lan {
                interface vlan.1;
            }
        }

......

interfaces {
    fe-0/0/0 {
        unit 0 {
            family inet {
                dhcp-client;
            }
        }
    }
    fe-0/0/1 {
        unit 0 {
            family ethernet-switching {
                port-mode access;
                vlan {
                    members 1;
                }
            }
        }
    }
    fe-0/0/2 {
        unit 0 {
            family ethernet-switching {
                port-mode access;
                vlan {
                    members 1;
                }
            }
        }
    }

...... etc

access {
    address-assignment {
        pool lan {
            family inet {
                network 192.168.62.0/24;
                range lan-range {
                    low 192.168.62.26;
                    high 192.168.62.36;
                }
                dhcp-attributes {
                    server-identifier 192.168.62.254;
                    name-server {
                        8.8.8.8;                    }
                    router {
                        192.168.62.254;
                    }
                }
            }
        }
    }
}

......

vlans {
    default {
        vlan-id 1;
        l3-interface vlan.1;
    }
}

Hi resplendent,

DHCP works in 4 packets as below.

Discover -Client to Server

Offer - Server to Client

Request - Client to Server

Ack - Server to Client

In your scenario we see Discover and Offer on SRX but we dont see Request from Client and thats the same reason why we state as "SELECTING".

The 2 possible reason for this is

1. the Offer from SRX is not reaching the client even though we see it on SRX ( We need to take a PCAP or tcpdump on client machine to confirm this)

2. The offer send from SRX is not acceptable for Client, again only the client knows why. You need to check if there is any specific requirements for this client.

Hi Suraj

Thanks for the reply.

After observing the packets across, it appears that the offer is not being sent by the SRX as broadcast.

This is when the EFTPOS device is connected to the SRX when using dhcp-local-server:

This is when the same EFTPOS device is connected to the router using the old dhcp server:

This is when a laptop is connected to the router using dhcp-local-server:

Any further suggestions?

Could it be that the offer is being sent as unicast instead of multicast?
Can I force the SRX to send offers via broadcast?

Hello,

Please try the below - I have no suitable DHCP client to test it, sorry:

aarseniev@labsrx# show | compare Nov 17 12:43:26 [edit system services] + dhcp-local-server { + overrides { + no-unicast-replies; + } + } [edit] aarseniev@labsrx# commit check Nov 17 12:43:38 configuration check succeeds

This stanza is hidden in 12.1X46, You have to type it in full.

HTH

Thx

Alex

Adding the override did the trick.
