Well, so far so good. I setup two en0 cards back to back and was able to configure a simple link. I tried using netperf to measure throughput and again, so far so good! On simple tcp stream tests, I was seeing /usr/local/netperf/netperf -l 60 -H 192.168.1.2 -t TCP_STREAM -i 10,2 -I 99,5 -- -m 4096 -s 57344 -S 57344 TCP STREAM TEST to 192.168.1.2 : +/-2.5% @ 99% conf. : histogram Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 57344 57344 4096 60.01 134.58 This is on a Intel 810e PIII 800e with 512MB of RAM. The box is going to be a border router running bgp. Now, the task is to do the conversion. On the other end, my upstream has interface ATM1/0/0.14 multipoint description - Sentex ATM ip address 192.168.1.1 255.255.255.252 no ip directed-broadcast no ip mroute-cache map-group atm atm pvc 15 0 130 aal5snap 35000 35000 inarp And the local Cisco 4700 has Interface ATM0 description Sentex ATM ip address 192.168.1.2 255.255.255.252 atm pvc 1 0 130 aal5snap 35000 35000 inarp map-group atm . . map-list ip 192.168.1.2 atm-vc 1 ip 192.168.1.1 atm-vc 1 I need to replace the Cisco 4700 with the FreeBSD box (I have a SM to MM m/c to do the fibre conversion). However, being an ATM novice, I am not sure how to translate the above config into a FreeBSD config. On the Cisco, I have atm pvc vcd vpi 130 rates rates ... and then inarp... If they are using inverse arp, how does this affect my configuration. Do I need to use the harp stack instead ? I am not sure how the inarp figures into this. On the two machines I have here, I did as the man pages suggested to bring the back to back config up, and that worked... But I am not sure if the above config only effects arp timeouts or works with an arp server somehow ? Any suggestions / tips would be much appreciated! ---Mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-atm" in the body of the message
