Scott & list,
I wish to clarify my earlier response (I was in a rush when I replied yesterday). The issue I was trying to describe was not because the SpectroServer primary NIC IP was not in the device's SNMP access list. Rather, it was because of routing rules in a private LAN. Here was my SpectroServer lab setup (9.1 H14 on Windows Server 2003): Monitored devices on private LAN: 192.168.18.2 192.168.18.3 192.168.18.4 SpectroServer: NIC 1: 10.17.221.130 (management LAN) NIC 2: 192.168.18.130 (private LAN) If SS NIC 1 is set as the primary NIC, then the SNMP request for TFTP dump will originate from SS NIC 2 (192.168.18.130), but it will direct the device to send the TFTP message to the primary NIC (NIC 1, 10.17.221.130). The device needs to be able to route to that address, and in my case, since SS NIC 2 is on private LAN, the devices had no idea how to get to 10.17.221.130 I figured this out by watching the NCM SNMP communication to the device IPs on NIC 2 using WireShark. Perhaps there is an NCM config setting I missed (in an RC file?), but in my haste to solve the issue, I chose to change NIC precedence on the SS itself since I could do that without penalty. When I changed the precedence of the SpectroServer NICs so that NIC 2 was primary and NIC 1 was secondary, the SNMP request for TFTP dump came from SS NIC 2 (192.168.18.130), AND directed the device to send the TFTP message to the same NIC (NIC 2, 192.168.18.130).

If your SS is multi-homed, running a wireshark and checking the IP's being used would tell you what's happening right away.

SNMP or Perl, TFTP or FTP? If SNMP are you using the Read-Write community string? If What type of device are you pulling the config from? Is the device in front of a firewall or behind it? Does the device have a NAT'ed address or a regular address? Regards, Stephen B.

Whenever I try to "Capture Config" I get an error stating I need to check the community string; everything is setup right though. I also see the NCMservice running on the server.
