    IPAM - DHCP Server Configuration

    rqrellebo

      Hi All,

       

      We are implementing IP Address Manager in one of our client. We're adding DHCP Server but we are having difficulty in the following:

       

      1. DHCP Servers are in remote location. We have to allow the port used by DHCP Server in the Firewall to communicate with Solarwinds. The problem is DHCP server used RPC port which is dynamic in nature. We can configure static port for RPC but the problem is one port (RPC port) is also configured for a specific application in the DHCP server. Ex: port 60001 is confgured for communication with Solarwinds Server and port 60002 is configured for other application. Do we have a way that we can configure a specific port in Solarwinds IPAM Server so that it will detect/communicate in port 60001 and not in 60002?

       

      2. Is there a way that we can monitor DHCP Server without enabling SNMP? Will the same information (reserve, available, used, transient) available without SNMP?  The way I understand the setup, IPAM will monitor DHCP Server via SNMP and RPC port. The client have strict security in their servers that SNMP should be disable.

       

      Thank You!

          Hi Raquel,

          1. you can setup DHCP server to use specific ports/ranges for RPC. RPC itself uses port 135 for Discovery, where it will offer a services on specified ports. That means, you have to have port 135 open and then your specified range on the Firewall and for example remote MMC console or IPAM should be able to connect over there.

          2. Definitively you dont need to have SNMP enabled on DHCP.DHCP server can be monitored using ICMP as an IP Address and RPC is used to download all Scopes stuff. SNMP is used basically to get some additional information for IP Address (HostName, MAC). And you may have also Neighbor scans, which asks specified devices on your network using SNMP for their ARP table records to find active hosts and MAC addresses.
