  • 1.  [5406] DHCP Server

    Posted Dec 17, 2018 10:40 AM

    Hi All,

     

    We need to move the DHCP server function from a Cisco switch to an Aruba Switch (5406). We configure the VLAN interfaces including IP and enable dhcp-server.

     

    We created the address pools correctly, but after activating DHCP Server globally and disabling the cisco switch the stations were unable to receive the IP address.

     

    The output of  show dhcp-server binding command was:

     

    Status and Counters - DHCP Server

     

     Address Pools         : 18  

      Automatic Bindings    : 10  

      Manual Bindings       : 0   

      Expired/Free Bindings : 7915

      DHCPACK               : 365       

      DHCPNAK               : 1  

     

    The DHCP configuration is similar to this one:

     

    ip route 0.0.0.0 0.0.0.0 10.16.10.254

    Ip routing

     

    vlan 10

     name "Test_VLAN"

     untagged A1,A3

     tagged A8

     ip address 192.168.1.1 255.255.255.0

     dhcp-server

     exit

     

    dhcp-server pool "Test-pool"

       default-router "192.168.1.1"

       dns-server "192.168.1.2"

       domain-name "mydomain.com"

       netbios-name-server "192.168.1.2"

       lease 00:00:05

       network 192.168.1.0 255.255.255.0

       range 192.168.1.10 192.168.1.200

       option 4 ip "192.168.1.2"

       option 9 ip "192.168.1.3"

       exit

     

    dhcp-server enable

     

    Do you have any tip?

     

    Thank you

    Try to set the dhcp-server to be authoritative for the pool "Test-pool" (using the command authoritative within the dhcp-server pool "Test-pool" context)...and is 5 minutes lease time correct (lease 00:00:05)?

    Hi Parnassus.

     

    We will try it on next maintenance window. 

    The current DHCP lease configuration is 8 hours. 00:08:00

     

    Thank you

    OK, 8 hours is far more reasonable as DHCP lease time.
