Solaris 11 link aggregation with multiple VLANs - not working
Hello,
I need help on fixing my network configuration on Sparc S7 server. I have configured (maybe incorrect) and can't make it work. I can't ping gateway.
I need to create an aggregation of two NICs and on that aggr0, there will be multiple VLAN taggings. LACP is enabled on switch side for both NICs and VLAN tagging is enabled on switch side by network guy. If I run snoop on net0 and net7, I can see packets incoming from those VLANs (example below).
Please help, what I am missing or configured incorrectly.
You do not define IP address of tagged VLAN on aggr0.
In your case you should :
Delete the address
Define the above address on VLAN interface vlan2170
Try pinging the gateway then.
Only native VLAN (untagged) will work on aggr0, while others such as 2170 will work on vlan2170 interface.
Those vlanNUM interfaces are the ones you configure IP address on for tagged VLAN(s) you created with dladm create-vlan ... over aggr0
I am expecting this setup, as the whole picture. Hope it makes sense.
One single interface (be it aggr or ipmp) with one IP will be presented to OVM (OV Manager) as host, as an IP with multiple VLAN tagged. After finishing the repository and other post-work, I should be create VM.
For example, I can get a request "create a Solaris-10 VM with 2 interfaces, one VLAN#2170 and one VLAN#2161". This interface will be visible on OVM Manager as bond0.
We have more than 20 VLANs, so don't want to configure 20 IPs for each VLAN. Ideally, all those VLANs should be tagged on this single interface. Any suggestion, how can I achieve it?
Please ask, if I am not able to explain it well.
You will then create a vsw (virtual switch) on top of aggr0
Then using that vsw add interfaces to VMs.
There is no need to create vlanNUM interfaces on the hypervisor in that case.
You only define vlan interfaces on hypervisor if you wish to define IP for the hypervisor itself.
Solaris 11 link aggregation - not working - can't ping gateway
This link was helpful and I got the idea that vlanNUM would be created on OVM/hypervisor level.
I deleted VLAN interfaces, recreated aggr0 with net0 and net7. But I can't ping its gateway. I can see packets incoming from two VLANs, if I snoop on net0, net7 and aggr0.
Per network guys, their side configurations are okay, but I will check again if my configurations are looking okay.
Am I missing something in this config ?

Reason: Corrected title
On aggr0 you can only define IP address from native VLAN on those ports.
If you wish to define a tagged IP on the hypervisor, you need to create vlan interface, then define IP on that.
If you wish to use the interface for virtual machines, you define a VSW with aggr0 link.
Then you add a vnet via ldm command using that VSW.
You can have both on the hypervisor, vlan interfaces and VSW above aggr0, but of course with different IP addresses (vm and hypervisor).
I would recommend reading about Oracle VM server for SPARC and a bit about networking as well
Looks like you are mixing hypervisor and vm part regarding network.

Hi,
This is Solaris-10 x86 platform.
I am not able to ping gateway associated with aggr50001. I am not getting idea, where could be issue. Please advise.

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.

Hi All, I am trying to aggregate the NIC's,(igb2 and igb3) (igb0 is used by the physical system and igb1 is used by primary-vsw0) to create the domains on that for faster data transfer, I followed the process for creating the aggregation, dladm create-aggr -d igb2 -d igb3 1

Hello,
I've been using mode 4 with four slaves, however looking at ifconfig showed that the traffic was not balanced correctly between the interfaces, the outgoing traffic has been alot higher on the last slave.
Example:
eth0 RX 123.2 GiB TX 22.5 GiB
eth1 RX 84.8 GiB TX 8.3 GiB

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...
