    IPAM - dhcp scope on a Cisco WLC

    briancartledge

      Can you advise if its possible to pull the scope details from dhcp running on a Cisco wireless lan controller. When I try a test the results are successful but no scopes are found.

       

      If its not currently supported do you have it on the roadmap?

       

      Thanks

          It is currently not supported by IPAM and we have it as feature request for the future implementation (sadly it's not a matter of a while to add support for this). When you want to use DHCP management from IPAM, the Cisco device has to support following commands:

           

          Cisco Commands that need to be supported:
          - ‘show running-config’
          - ‘show ip dhcp pool’
          - ‘show ip dhcp binding’

              Hi,

              have you tried that command on your Cisco devices?

                  I have a 5508 controller also acting as a DHCP server for a select network.

                   

                  'show ip running-config' works.

                   

                  show ip dhcp pool does not. the IP part needs to be removed -

                   

                  show dhcp detailed  <scope name>

                  show dhcp summary  <-- shows scope name

                  show dhcp leases

                  show dhcp stats

                   

                   

                  for example:

                   

                  (Cisco Controller) >show dhcp summary

                    Scope Name                   Enabled          Address Range
                  guest users                      Yes      172.16.32.1 -> 172.16.35.225

                   

                   

                  Cisco Controller) >show dhcp detailed 'guest users'

                      Same results here for the pool commands but "show ip running-config" isn't recognised.

                       

                      show running-config or show run-config work okay

                       

                      (Cisco Controller) >show running-config

                      Notice: "show running-config" has been changed to be an alias to "show run-config".
                      Use "show run-config commands" to display the configuration commands.
