How much of the vlan/bridge stuff is off-loaded to the ethernet card? Would chaning out my em0 for an igb0 affect uni-cast flooding in any way? Rudy On 12/16/2010 04:17 PM, Rudy wrote: I am having issues when I add 3 vlans (all off of em1) to bridge0. [1] when I ping ips on 2 of the 3 vla

Hi, Alex! You can make virtual NIC via netgraph. 1. ng_ether automatic attached to every physical NICs on load module. 2. connect ng_bridge to upper and lower hooks on ng_ether 3. create and connect ng_eiface to ng_bridge and you will get new NIC ngethX with its own MAC address and IP addrs too.

Hi! I run pretty busy 4-core router that has 4 gigabit ethernet interfaces: em0 and em1 grouped to lagg0 that has IP address and igb0 and igb1 grouped to lagg1 that has no IP address but many vlans that carry PPPoE traffic. sysctl net.inet.ip.intr_queue_drops shows me 15408340 packet drops due to

Hi all, I just wonder that if there are virtual nic functionalities which provides MAC address? I need to run ISC DHCP Server on 4 different IP's within one sever, however I have only 2 NICs connected to the server. I need different MAC Address for those IPs in order to run it properly, so bxn0:l s

igb(4) OACTIVE logic handling

2010-12-17 Thread Sean Bruno
We're seeing igb(4) hit the OACTIVE handling parts of igb_start_locked() on 7 with hw.igb.rxd/txd set to 4096 periodically and seeing the machines fall off the network soon after. The logic to handle the unset of OACTIVE in igb_txeof() doesn't ever seem to fire and the machine is only accessible o
