Hello all.
I'm very new to NetBSD but am quite familiar with FreeBSD and Linux. I am
considering NetBSD for a project, but need to see if its feature set suits.
I have an existing Linux router that borders a network I administer. The WAN
interface is a Fore (now Marconi) PC200e 155 Mbps ATM adaptor. Our service
provider requires that we use interface/PVC QoS/Traffic control. We
originally tried FreeBSD, but it's atm command set did not seem to have the
commands required to configure the settings as we required. We eventually
had to turn to Linux as a quick fix. We use the following script on the
Linux router to set up the interfaces (I have changed the specific to
protect the innocent :)
atmarpd -b
atmarp -c atm0
ifconfig atm0 192.168.1.82 netmask 255.255.255.252 up
atmarp -s 192.168.1.81 0.33 qos cbr,aal5:max_pcr=6144kbps
atmarp -c atm1
ifconfig atm1 192.168.2.130 netmask 255.255.255.252 up
atmarp -s 192.168.2.129 0.34 qos cbr,aal5:max_pcr=2048kbps
The max_pcr is the important bit of the above commands. I could get all the
other settings into FreeBSD except for that command. I believe that is
because the HARP project does not support that feature. Does NetBSD share a
common code in this area with FreeBSD, or is there hope of us converting the
system to BSD? Any suggestions would be greatly appreciated!
