X-BeenThere: freebsd-net@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Networking and TCP/IP with FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 15 Mar 2005 05:17:01 -0000 Testing my network, I just noticed the following: --- 200.46.204.1 ping statistics --- 4 packets transmitted, 4 packets received, 0% packet loss round-trip min/avg/max/stddev = 399.664/407.119/420.315/8.267 ms --- 200.46.208.1 ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max/stddev = 373.045/409.266/453.402/33.280 ms 400ms to my default router seems a wee bit high ... I'm suspecting that it has to do with: Mar 15 01:13:28 neptune last message repeated 10 times Mar 15 01:13:28 neptune /kernel: arp: 200.46.204.1 is on em0 but got reply from 00:0b:bf:42:a8:06 on em1 Mar 15 01:13:28 neptune /kernel: arp: 200.46.208.1 is on em1 but got reply from 00:0b:bf:42:a8:06 on em0 In order to provide network redundancy, and simplify our scripting, with have one network bound to one ethernet port, and the other network bound to the second one on the same machine ... I'm plugging everything into a Cisco 2924 ... is there some way, either on the FreeBSD side, or Cisco, of 'cleaning this up'? ---- Marc G.
