Re: etherchannel on 5.2.1 - possible?
When I checked the various methods a while back all resulted in performance drop not increase on a dual port intel etherxpress Pro 100. If anyone has different experiences I also would be interested. Also noted was that Gb performance on nge was also lower than that of fxp on 100Mb especially when using link0 on the fxp. Notes: Results using ftp ( proftpd ). Performance increase using nge was obtained when using single processor kernel and polling enabled without this interrupt rates appeared to be overloading the system.

I have used the ng_fec netgraph module with both broadcom 5703X and HP NC7170 nics (uses em driver). This is how to set it up: First you have to have the ng_fec module loaded. Then, # ngctl mkpeer fec dummy fec # ngctl msg fec0: add_iface '"bge0"' # ngctl msg fec0: add_iface '"bge1"' Obviously replace bge with em or whatever other driver you are using. ng_fec supports up to 4 links. At this point, you will have a fec0 interface that you can manipulate normally with ifconfig. I have noticed that sometimes I have to bring the interface up and down a couple of times to get it to start passing traffic. Whenever you 'ifconfig up' or assign an address to fec0 it resets the bundle. One thing that is annoying is that ng_fec doesn't work with vlans. There is an ng_vlan module that was recently released, but ng_fec doesn't work with it because it isn't quite like other netgraph modules. Almost all of my freebsd machines use vlans, so I am not making heavy use of ng_fec. We aren't pushing enough data to make it really necessary anyway. There is also ng_one2many which does implement failover and channel bonding but not using the etherchannel technique. I think it uses round robin. -Will ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
