The hash includes the Ethernet source and destination address, and, if available, the VLAN tag, and the IPv4/IPv6 source and destination address." and once in Example 32-1, which is presumably being used as the cookbook for this project: "Since frame ordering is mandatory on Ethernet links then any traffic between two stations always flows over the same physical link limiting the maximum speed to that of one interface. The transmit algorithm attempts to use as much information as it can to distinguish different traffic flows and balance across the available interfaces." Has use of Gig ethernet been considered? -- --Jon Radel j...@radel.com

about the top speed of Link Aggregation and A STRANGE PROBLEM
Hi ： I use a dell server making Link Aggregation with 6 ports and make it be a FTP server. When I use 2 pc connect the server at the same time. The top speed of the server can be 200MB/S. And in the transmission I cut off one of working ports,the discard connetion will be use another working port , it can't use a free port. So the top speed is down to 100MB/s. And I use 2 pc connect again, It stil use the last port. So I cut it off. Something happens,it will use 2 free ports.And the top speed is up to 200MB/s. What is the matter? And I use 3 pc connect,they use 3 ports. I cut one of them.It will use another working port. Now there are two working ports,3 free ports,1 cut off.When I cut another port, It will use 2 free ports.Now it turn back for using 3 ports, Why ?The LACP protocol's problem? And I have a another question. I make RAID 0 in my server , Why the top speed is 200MB/S ? and how could I do can make 2 server transport with Link Aggregation ? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Issues with Link Aggregation
Hello Freebsd-Questions, I have an Asus laptop running FreeBSD 8.2-RELEASE-p4. I have successfully configured both the wired and wireless interfaces. They both work individually. I use the wireless interface more than the wired, so I have attempted to us link aggregation (LAGG) to tie the two together so either can be used when connected. lagg and iwn have been added into a custom compiled kernel. FreeBSD on this Asus uses alc0 for the wired interface and iwn(wlan0) for the wireless interface. The following is in my rc.conf: ifconfig_alc0="up" wlans_iwn0="wlan0" ifconfig_wlan0="up wpa" cloned_interfaces="lagg0" ifconfig_lagg0="laggproto failover laggport wlan0 laggport alc0" ipv4_addrs_lagg0="192.168.2.90/24" defaultrouter="192.168.2.1" hostname="asus.local" Looking at various documentation shows this should support wlan0 as the master and alc0 as the failover. Everything is working like it should. However, every so often, I get messages on the console stating: alc0: phy read timeout : 0 alc0: phy read timeout : 17 alc0: phy read timeout : 1 ... alc0: phy read timeout : 1 Even though this is happening, there doesn't appear to be any issues. Can anyone shed light on why these messages are showing up? -- If at first you don't succeed, so much for skydiving." ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Link Aggregation
All, I am having some difficulty in getting any protocol link aggregate to work for network teaming. I have read the chapter in the handbook and followed the instructions there. Unfortunately, it always comes up "no carrier". I have tried the failover, loadbalance and lacp (with an enabled lacp switch) to no avail. The link members are showing as active but the lagg0 interface reports as "no carrirer"". I have assigned it a valid IP address, etc. I have tried this on two different "PC", one virtual in VMWare running FreeBSD 6.3 amd64 and on a Dell PE 1300 running FreeBSD 6.3 i386 (I know it is old, just for testing). Both behave identically. No updates have been made to either machine so if that is the issue let me know. Other than that, I am at a lose (not much comes up in Google, at least not in English). Thanks for the help.

See the ng_fec manpage for the syntax. It doesn't support LACP autonegotiation, though, so you will have to manually set a matching configuration on your swtich. -- Dan Nelson [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

FreeBSD link aggregation / trunking / channel bonding
I have been googling for a while now and I can't find a "how to" on doing this with FreeBSD. Please point me to a book, or white paper, or site if you know of one.
