Consider a case in which a cluster node has two public network interface in a IPMP group and a logical hostname (ip addr) is also assigned to one of the interfaces.
If an SNMP trap is generated from this cluster node, what would be the source IP address in the IP header of the trap?
Is there a way to restrict the source IP addr to one of the interfaces?
There is only IPMP group so I'm not sure what you mean by active/standby groups. If your question meant to ask whether the interfaces within the group are in active/standby, the answer is no.
Even if they were active/standby and the trap always travels over the active interface, the question still remains whether the source IP address would be the physical address or the logical address, assuming the logical address is also assigned to the same interface.
See the docs for a description of active/active and active/standby configurations (http://docs.sun.com/app/docs/doc/816-4554/6maoq027j?q=IP+multipathing&a=vi ew)
I'm pretty sure the source address will always be the physical address of the system on that subnet, rather than the logical address. May be with an active/standby configuration, you can constrain it to always be one address. The best option is to try it.
