IPMP over VLAN questions.

Hi Folks,

I am currently moving systems to a new environment, with some changes to the network requirements on the systems.

One of these changes is moving from just standard IPMP to using IPMP on top of a VLAN, I have used VLAN tagging befor without issue - however not with IPMP.

What I get when I configure the interfaces is;
Code:
igb0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 12
        inet 0.0.0.0 netmask ff000000 broadcast 0.255.255.255
        ether a0:36:9f:b5:a:b8
igb4: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 14
        inet 0.0.0.0 netmask ff000000
        ether a0:36:9f:b5:a:38
igb140000: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 17
        inet 0.0.0.0 netmask ff000000
        groupname backup
        ether a0:36:9f:b5:a:b8
igb140004: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 18
        inet 0.0.0.0 netmask ff000000
        groupname backup
        ether a0:36:9f:b5:a:38

The contents of the hostname files are;

Code:
hostname.140004:group backup up
hostname.igb0:0.0.0.0 up
hostname.igb140000:sphsunvs01-bkp netmask + broadcast + group backup up
hostname.igb4:0.0.0.0 up

The entry in the /etc/hosts file is just the VLAN 140 IP address and the host name, I know I'm missing something really simple here.

This is a SUN T5-2 with;

Code:
                   Oracle Solaris 10 1/13 s10s_u11wos_24a SPARC

SunOS sphsunvs01 5.10 Generic_150400-46 sun4v sparc sun4v

There is sufficient I/O on the system;

Code:

I can see the VLAN tagged traffic on the interfaces.

Any pointers will be welcome, so will suitable critical comments!

Both igb0 and igb4 have same mac address, is this intentional ?

I suspect that all the interfaces have system wide mac, check the output of :
Code:
eeprom local-mac-address?

In that case you will need to switch that value, and reboot the host to have unique macs for all interfaces.
After that you can use them for grouping.

Hope that helps

Hi Peasant,

Thanks for the suggestion, but the local-mac-assress is set to true and the physical and VLAN interfaces are presenting with the correct mac addressess.

I'm pretty sure that when I find the solution for this, I'm going to end up kicking myself.
