  • 1.  DHCP config on 6300M

    Posted Jun 11, 2025 06:53 AM

    Hello,

    I have a central Windows DHCP server that I use for 99.9% of our devices, but I have a couple of temperature tracking boxes that do not like some of the default DHCP options that our Windows server provides.  Therefore I would like to set up a local DHCP server on a 6300M switch for use with these devices.


    L3 device is an 8325 switch with a separate VLAN without IP helper for this new VLAN I want to set up

    interface vlan 41
    ip address 10.8.41.254/24

    l3-counters

    This VLAN is allowed on the uplink to the 6300M switch


    L2 device is the 6300M switch

    VLAN is allowed on the uplink to the 8325


    dhcp-server vrf sns
        pool primary-pool
            range 10.8.41.1 10.8.41.10 prefix-len 24
            default-router 10.8.41.254
            dns-server 10.99.1.29 10.254.251.91
            lease 12:00:00
            exit
        authoritative
        enable


    However, the output is as follows where the config status is always showing as Pending.

    FWE-IDF4-232#   sh dhcp-server vrf sns

    VRF Name           : sns
    DHCP Server        : enabled
    Operational State  : operational
    Authoritative Mode : true

    Config_status  : Pending

    Pool Name          : primary-pool
    Lease Duration     : 12:00:00

    DHCP dynamic IP allocation
    ----------------------------
    Start-IP-Address           End-IP-Address             Prefix-Length
    -----------------          ---------------            -------------
    10.8.41.1                  10.8.41.10                 24


    DHCP Server options
    ---------------------
    ***************************************************
    Note:DHCP Server well known option number mapping:
    default-router(3), Dns-server(6), Domain-name(15),
    Netbios-name-server(44), Netbios-node-type(46)
    ***************************************************
    Option-Number       Option-Type          Option-Value
    --------------      ------------         -------------
     3                  ip                   10.8.41.254
     6                  ip                   10.99.1.29 10.254.251.91


    DHCP Server static IP allocation
    ----------------------------------
    DHCP Server static host is not configured.


    BOOTP Options
    ---------------
    Boot-File-Name            TFTP-Server-Name            TFTP-Server-Address            Next-Server-Address
    ---------------           -----------------         ---------------------           ---------------------
    *                         *                              *                              *


    Therefore, any idea how I remove the config status as Pending?  Central is not used on this device.

    Hi

     

    It looks like you don't have an IP interface in VRF sns that can support your DHCP server. So, attach a vlan41 interface to VRF sns on the 6300M and set an IP or move the DHCP server to your 8325 device. 

     

    Regards,

    Thomas

    That was it...  I was just missing a local IP address on vlan 41.  Thank you for your help!
