I think you have active/active, check with
It can lead to hickups - sudden delay or packet loss.
For active/standby have
hostname.igb1
No second IP-address.

In case you want to go for a symmetric active/active aggregate with LACP (this is not called IPMP by Sun and Oracle):
1. enable LACP on the LAN switch port
2. create an executable script on the local disk
The script is for bge0 and bge1; rename them to your NIC drivers.
Run the script from a console (e.g. an ILO board - not over ssh!)

Note they advertise -l active but usually it should be -l passive because the LAN switch is the active part.
Because the aggregated links are hidden, netstat -i 1 shows the sum only, while the per-link packets are shown with dladm show-aggr -s -i 1.

Greatly appreciate the examples.
I am trying to setup ACTIVE,ACTIVE IPMP and do a packet sniff to see what are the actual IPs and mac address being send out of both interfaces... but sadly.. solaris doesn't seems to have wireshark
I don't know if you still need more info but I thought I would Chime in as I recently switched from IPMP over to Link-aggr and LACP.
What we found is due the application we were using, Load spreading was not working as expected.
IPMP is supposed to load balance only outbound traffic based on my research. What I found when reviewing dlstats, were only one port was actually being used.
- Due to this our application was impacted. Users reported slow connectivity during peek times. We took a look at the server and there were plenty resources available since this is a new implementation and only one application on the server at the time. The application is network heavy. (IPMP configuration is what was recommended to us. There is a possibility that when it was setup, it was not done correctly).
As Solaris was pretty new to me and I came into the project half way, I suggested switching over to using link aggregation instead. Once switched over, performance has improved from the user experience which was the goal.
Not sure if this helps.

Hi,
I have Solaris-9 server, V240.
I got alert that one of the interface on IPMP configuration, is failed. Found that two IPs (192.168.120.32 and 192.168.120.35) are not pingable from this server. These two IPs were plumbed on another server and that is decommissioned now. That is the reason,... (5 Replies)
Hi all,
Just a few questions ->
Is an "OFFLINE" interface going back to "ONLINE" consider as a failback by IPMP ?
I have "FAILBACK=no" in my /etc/default/mpathd; however when i do the following
(igb0 and igb7 are in the same ipmp link based group)
q1) why does "if_mpadm -r igb7" cause... (0 Replies)

All.
I am trying to create a 10 branded zone on a Sol 11.1 T5. The Global is using IPMP...so aggregating is out of the question. Has anyone successfully created a branded zone with IPMP? If they have can you please show me the steps you took to get this to run.
Thanks (4 Replies)
Hi,
This may have already been raised previously so sorry for the duplication. What I want to achieve is have a physical server using link based IPMP setup in the global zone (not problem doing that) and then create a zone set as Shared-IP so when the servers NIC has an issue the IP will... (0 Replies)

Does Veritas Cluster work with IPMP on Solaris 10?
If anyone has set it up do you have a doc or tips?
I have heard several different statements ranging from , not working at all to Yes it works! Great How?
