Hello,

Below are quick steps to configure internal DHCPv6 server on your OmniSwitch:

  1. Navigate to /flash/switch directory: → (cd /flash/switch)
  2. Create and customize the dhcpdv6.conf (Configuration File) and dhcpdv6.pcy (Policy File) files according to your requirements. Use the vi command to modify the existing configuration file. (-> vi dhcpdv6.conf)
  3. Save changes to the files (.wq)
  4. Restart DHCPv6 server: (-> dhcpv6-server restart)
  5. Enable DHCPv6 server: (-> dhcpv6-server enable)

Following is example dhcpdv6.pcy file:
AbusiveClientMonitorPeriod=30
AbusiveClientWarningCount=30
AbusiveClientLockout=0
AddManualToGlobalDuidPool=1
AllowClientPacketsWithInvalidOptions=1
AllowUnencodedFqdn=1
CheckTransactionID=0
ClientFqdnOptionSupport=client
ClientHostNameProcessing=correct
ClientProcessingWaitTime=3000

DHCPv6SocketAddr=2620:0:60:1480::3
DuidWarningsToEventLog=0
