  • 1.  Port Assigned IP DHCP Pool

    Posted Aug 25, 2025 03:35 PM

    Hey everyone.  I'm looking for some expert advice from some of the experienced HPE Aruba users here.  I am decent with Cisco networking switches, but a newb when it comes to HPE.

    I have a task that I cannot figure out for the life of me.  I can get it to work on Cisco, but not on HPE.  Basically I want to be able to plug in a POE device to a port, and it gets and IP from a DHCP pool I set. For example, the command script is:

    ip dhcp pool DEVce-DHCP-pool
     network 192.168.10.0 255.255.255.0
     default-router 192.168.10.1 
     lease infinite
     address 192.168.10.101 client-id "g1/0/1" ascii
     address 192.168.10.102 client-id "g1/0/2" ascii
     address 192.168.10.103 client-id "g1/0/3" ascii
     address 192.168.10.104 client-id "g1/0/4" ascii

        repeated to g1/0/24


    I want to replicate this on an HPE Aruba 6300M and 6200F switch. 

    Thanks in advance.

    Here is a sample config for CX switches.

    ================
    dhcp-server vrf default
        pool TEST
            range 10.10.30.20 10.10.30.30 prefix-len 24
            default-router 10.10.30.1
            dns-server 192.168.1.131
            lease 00:02:00
            exit
        enable

    interface 1/1/2
        no shutdown
        no routing
        vlan access 30


    interface vlan 30
        ip address 10.10.30.1/24

    So when I tried this config, it did assign an IP within the range.

    But I was hoping when I plugged the POE device into interface 1/1/1 it gave me the first ip of that range of 10.10.30.20.

    But instead it assigned 10.10.30.27.

    Any idea on how to get it to do this via DHCP pool?

    interface 1/1/1 = 10.10.30.21
    interface 1/1/2 = 10.10.30.22
    interface 1/1/3 = 10.10.30.23
    interface 1/1/4 = 10.10.30.24
    interface 1/1/5 = 10.10.30.25

    I don't think you can change this behaviour.

    You can use 'static-bind' to map a client MAC address to a specific IP adress. (page 114 in the document).

    In that way it doesn't matter in which port you plug a device, it always gets the same IP.
