Hi,
I have Solaris-10 server and link aggregation is configured on this in below way
There will be switch replacement, so one by one, link will go down from one side. Before that activity, is there any way to check/test, if server will work fine, if one side goes down ? In same way, as used to check by if_mpadm -d in ipmp.

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.

igb(7D) Devices igb(7D)NAME
igb - Intel 82575 1Gb PCI Express NIC Driver
SYNOPSIS
/dev/igb*
DESCRIPTION
The igb Gigabit Ethernet driver is a multi-threaded, loadable, clonable, GLD-based STREAMS driver supporting the Data Link Provider
Interface, dlpi(7P), on Intel 82575 Gigabit Ethernet controllers.
The igb driver functions include controller initialization, frame transmit and receive, promiscuous and multicast support, and error
recovery and reporting.
The igb driver and hardware support auto-negotiation, a protocol specified by the 1000 Base-T standard. Auto-negotiation allows each
device to advertise its capabilities and discover those of its peer (link partner). The highest common denominator supported by both
link partners is automatically selected, yielding the greatest available throughput, while requiring no manual configuration. The
igb driver also allows you to configure the advertised capabilities to less than the maximum (where the full speed of the interface is
not required), or to force a specific mode of operation, irrespective of the link partner's advertised capabilities.
APPLICATION PROGRAMMING INTERFACE
The cloning character-special device, /dev/igb, is used to access all Intel 82575 Gigabit devices installed within the system.
The igb driver is managed by the dladm(1M) command line utility, which allows VLANs to be defined on top of igb instances and for igb
instances to be aggregated. See dladm(1M) for more details.
You must send an explicit DL_ATTACH_REQ message to associate the opened stream with a particular device (PPA). The PPA ID is interpreted as
an unsigned integer data type and indicates the corresponding device instance (unit) number. The driver returns an error (DL_ERROR_ACK) if
the PPA field value does not correspond to a valid device instance number for the system. The device is initialized on first attach and de-
initialized (stopped) at last detach.
The values returned by the driver in the DL_INFO_ACK primitive in response to your DL_INFO_REQ are:
o Maximum SDU is 9000.
o Minimum SDU is 0.
o DLSAP address length is 8.
o MAC type is DL_ETHER.
o SAP (Service Access Point) length value is -2, meaning the physical address component is followed immediately by a 2-byte SAP
component within the DLSAP address.
o Broadcast address value is the Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF).
Once in the DL_ATTACHED state, you must send a DL_BIND_REQ to associate a particular SAP with the stream.
CONFIGURATION
By default, the igb driver performs auto-negotiation to select the link speed and mode. Link speed and mode can be any one of the follow-
ing, (as described in the IEEE803.2 standard):
1000 Mbps, full-duplex.
100 Mbps, full-duplex.
100 Mbps, half-duplex.
10 Mbps, full-duplex.
10 Mbps, half-duplex.
The auto-negotiation protocol automatically selects speed (1000 Mbps, 100 Mbps, or 10 Mbps) and operation mode (full-duplex or half-duplex)
as the highest common denominator supported by both link partners.
Alternatively, you can set the capabilities advertised by the igb device using ndd(1M). The driver supports a number of parameters whose
names begin with adv_ (see below). Each of these parameters contains a boolean value that determines if the device advertises that mode of
operation. For example, the adv_1000fdx_cap parameter indicates if 1000M full duplex is advertised to link partner. The adv_autoneg cap
parameter controls whether auto-negotiation is performed. If adv_autoneg_cap is set to 0, the driver forces the mode of operation
selected by the first non-zero parameter in priority order as shown below:
(highest priority/greatest throughput)
adv_1000fdx_cap 1000Mbps full duplex
adv_100fdx_cap 100Mpbs full duplex
adv_100hdx_cap 100Mbps half duplex
adv_10fdx_cap 10Mpbs full duplex
adv_10hdx_cap 10Mpbs half duplex
(lowest priority/least throughput)
All capabilities default to enabled. Note that changing any capability parameter causes the link to go down while the link partners renego-
tiate the link speed/duplex using the newly changed capabilities.
