  • 1.  DHCP server issue on Aruba Gateway 9012

    Posted Sep 14, 2025 07:40 AM

    Hello, I'm facing a rather annoying issue on Aruba Gateway 9012.
    I have configured a DHCP server on the VLAN, but sometimes the client device receives an IP address and sometimes it doesn't.

    I checked the network logs and DHCP-related logs (included below), and it seems the DHCP server service might be having problems.
    Could this issue be related to the firmware version? I noticed the device is running an old firmware: ArubaOS (MODEL: Aruba9012), Version 8.7.0.0-2.3.0.8.

    Please help me check this issue. Thank you all!

    You are running on an old Aruba OS and i would recommend you to upgrade it to the latest recommended one.

    In Addition:

    dhcpdwrap ... DHCP Server received signal 9 → the DHCP process was hard-killed (SIGKILL) by the watchdog. That will drop offers/acks mid-flow and cause intermittent failures.

    publisher ... 'dhcpd config status (service not found)' → the publisher tried to talk to the DHCP service while it wasn't up yet (between crashes/restarts).

    pim ... Could not allocate bw contract cpbwc-ipv4-dhcp-sync → control-plane bandwidth contract could not be reserved for DHCP sync. That's another sign the process/resources around DHCP weren't healthy.

    Vlan <id> entry already present right after a crash → duplicate/dirty state in the DHCP/VLAN mapping table after the restart.

    You should check if DHCP Service isn't flapping and also if potentially you might have a DHCP Pool exhaustion.

    DHCP service is enabled and DHCP pool has many IP addresses available, but it is unstable sometimes client is granted DHCP, sometimes no response. I have upgraded firmware to 8.12.6 but still have such log messages.

    Is the Gateway running standalone or in a cluster?
    Is the DHCP service bound to the correct VLAN interfaces only (no overlapping)?

    Check:
    show ip dhcp pool
    show ip dhcp statistics
    show ip dhcp binding
    show processes application | include dhcp
    show processes top
    show memory
