Link aggregation
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 machines still uses only one link, is that true?

Hi everybody,
One client asked me to configure network failover and load balancing for two Ethernet interfaces, I tried IPMP but I was unable to do so, because he's using his Gateway as firewall and PING is disabled.

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.

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?

ifenslave-2.6
IFENSLAVE(8) BSD System Manager's Manual IFENSLAVE(8)
NAME
ifenslave -- Attach and detach slave network devices to a bonding device.
SYNOPSIS
ifenslave [-acdfhuvV] [--all-interfaces] [--change-active] [--detach] [--force] [--help] [--usage] [--verbose] [--version] master slave ...
DESCRIPTION
ifenslave is a tool to attach and detach slave network devices to a bonding device. A bonding device will act like a normal Ethernet network
device to the kernel, but will send out the packets via the slave devices using a simple round-robin scheduler. This allows for simple load-
balancing, identical to "channel bonding" or "trunking" techniques used in switches.
The kernel must have support for bonding devices for ifenslave to be useful.
OPTIONS
-a, --all-interfaces
Show information about all interfaces.
-c, --change-active
Change active slave.
-d, --detach
Removes slave interfaces from the bonding device.
-f, --force
Force actions to be taken if one of the specified interfaces appears not to belong to an Ethernet device.
-h, --help
Display a help message and exit.
-u, --usage
Show usage information and exit.
-v, --verbose
Print warning and debug messages.
-V, --version
Show version information and exit.
If not options are given, the default action will be to enslave interfaces.
EXAMPLE
The following example shows how to setup a bonding device and enslave two real Ethernet devices to it:
# modprobe bonding
# ifconfig bond0 192.168.0.1 netmask 255.255.0.0
# ifenslave bond0 eth0 eth1
