Thanks.
I was able to find a server, on which I can do "pull the cable test".
From below output, it shows that bnx1 cable was pulled out. since aggr is configured igb2 took the traffic and all link sustained. But first line shows "address: 3c:d9:2b:f9:20:5e (auto)" and this MAC address is for bnx1.
Since igb2 took all the traffic now and its mac is f4:ce:46:a7:df:ba , should it not show in auto ? Sorry, I am confused in understanding this.

I have some linux machines that I am trying to increase the throughput to on a single connection. They connect to a switch with two 1GbE lines and the switch does not have Link Aggregation support for these machines. I have tried bonding with balance-rr, balance-alb, but the machines can only...

Hi,
I need to setup a hacmp cluster (my first one, we usually use VCS on AIX), but I require more network bandwith than a normal gigabit etherchannel setup can provide, so I am thinking about using linkaggregation - 2 active adapters to one switch and a single backup adapter to another switch...

Hi,
Hoping someone can offer some advice on something i have not dealt with before.
We have a server that seems to have some very strange configuration done on it. It has 2 physical NIC's and rather than both be aggregated into LAN900 we have 1 in LAN900 and 1 in LAN901? (See Below)... (2 Replies)
Me again :)
I'm trying to find a page describing the L2, L3 und L4 modes of dladm.
It's nice to read "hashed by ip header", but how should I use that?
On the file-server it's ok to have the six interfaces serving six clients each on it's own. But an rsync connection via switch between two... (8 Replies)
Hi,
I want to Break the Link Aggregation. My aggregation are lan0+lan1 = lan900.
Now I want to break this and put the IP in lan0. But i have cluster environment and this is the main database server.
So It need to change in cluster script.
But I dont know where I have to change it.
Please... (1 Reply)
Hi,
I'm not from the Solaris world and some of these things are new to me. Can someone tell me if it is possible to configure link aggregation without using LACP?
I am told etherchannel was setup without LACP. (3 Replies)
I have setup link aggregation with 3 interfaces on my solaris 10 system.
All looks good but my problem is that the traffic is only going out bge0 and not the other 2 links.

LAGG(4) BSD Kernel Interfaces Manual LAGG(4)NAME
lagg -- link aggregation and link failover interface
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device lagg
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_lagg_load="YES"
DESCRIPTION
The lagg interface allows aggregation of multiple network interfaces as one virtual lagg interface for the purpose of providing fault-toler-
ance and high-speed links.
A lagg interface can be created using the ifconfig laggN create command. It can use different link aggregation protocols specified using the
laggproto proto option. Child interfaces can be added using the laggport child-iface option and removed using the -laggport child-iface
option.
The driver currently supports the aggregation protocols failover (the default), fec, lacp, loadbalance, roundrobin, and none. The protocols
determine which ports are used for outgoing traffic and whether a specific port accepts incoming traffic. The interface link state is used
to validate if the port is active or not.
failover Sends traffic only through the active port. If the master port becomes unavailable, the next active port is used. The first
interface added is the master port; any interfaces added after that are used as failover devices.
By default, received traffic is only accepted when they are received through the active port. This constraint can be relaxed by
setting the net.link.lagg.failover_rx_all sysctl(8) variable to a nonzero value, which is useful for certain bridged network
setups.
fec Supports Cisco EtherChannel. This is a static setup and does not negotiate aggregation with the peer or exchange frames to mon-
itor the link.
lacp Supports the IEEE 802.3ad Link Aggregation Control Protocol (LACP) and the Marker Protocol. LACP will negotiate a set of aggre-
gable links with the peer in to one or more Link Aggregated Groups. Each LAG is composed of ports of the same speed, set to
full-duplex operation. The traffic will be balanced across the ports in the LAG with the greatest total speed, in most cases
there will only be one LAG which contains all ports. In the event of changes in physical connectivity, Link Aggregation will
quickly converge to a new configuration.
loadbalance Balances outgoing traffic across the active ports based on hashed protocol header information and accepts incoming traffic from
any active port. This is a static setup and does not negotiate aggregation with the peer or exchange frames to monitor the
link. The hash includes the Ethernet source and destination address, and, if available, the VLAN tag, and the IP source and
destination address.
roundrobin Distributes outgoing traffic using a round-robin scheduler through all active ports and accepts incoming traffic from any active
port.
none This protocol is intended to do nothing: it disables any traffic without disabling the lagg interface itself.
Each lagg interface is created at runtime using interface cloning. This is most easily done with the ifconfig(8) create command or using the
cloned_interfaces variable in rc.conf(5).
The MTU of the first interface to be added is used as the lagg MTU. All additional interfaces are required to have exactly the same value.
EXAMPLES
Create a 802.3ad link aggregation using LACP with two bge(4) Gigabit Ethernet interfaces:
# ifconfig bge0 up
# ifconfig bge1 up
# ifconfig lagg0 laggproto lacp laggport bge0 laggport bge1
192.168.1.1 netmask 255.255.255.0
The following example uses an active failover interface to set up roaming between wired and wireless networks using two network devices.
Whenever the wired master interface is unplugged, the wireless failover device will be used:
# ifconfig em0 up
# ifconfig ath0 ether 00:11:22:33:44:55
# ifconfig create wlan0 wlandev ath0 ssid my_net up
# ifconfig lagg0 laggproto failover laggport em0 laggport wlan0
192.168.1.1 netmask 255.255.255.0
(Note the mac address of the wireless device is forced to match the wired device as a workaround.)

The lagg device first appeared in FreeBSD 6.3.
AUTHORS
The lagg driver was written under the name trunk by Reyk Floeter <reyk@openbsd.org>. The LACP implementation was written by YAMAMOTO Takashi
for NetBSD.
BUGS
There is no way to configure LACP administrative variables, including system and port priorities. The current implementation always performs
active-mode LACP and uses 0x8000 as system and port priorities.
