I know Seb is going to add the dladm administration support in the
non-global zones. I suppose after that, we will be able to create a bridge
in the non-global zones too? Of course, we can only create bridges between
data-links that belongs to that specific zone.
No, I wouldn't expect bridges to be usable in non-global zones. You
need access to a real mac to use them, and we have no way (that I know
of) to put real macs in to non-global zones. A mere VLAN won't do it.
It's like an aggregation. You can't create aggregations in
non-global zones, can you?
I don't see why we cannot, if we assign both bge0 and bge1 to a exclusive
zone, we should be able to aggregate it in that zone. Certainly there my
not be any useful user case for it.
How do you tell whether a MAC is a real mac or virtualized MAC? Say a xnf
data-link is DomU, how do you tell this does not correspond to a real
physical device?
I asked because in theory other types of
data-links (VNICs, aggregations) only take effect and starts the
underlying MAC once we plumb it, and that would allow things like changing
the MTU of underlying device much simpler. So I am wondering whether there
is an equivalence of "plumbing" a bridge.
Not exactly, but you can stop and start the "bridge:<name>" SMF
service, and that has the effect you're after. When the SMF instance
is disabled, the daemon stops running, the bridge instance is
disconnected from all of its links, and is freed.
Temporarily stopping the bridge instance is how I play around with
MTU. I recommend setting MTUs coherently first, though, before
configuring the bridge.
Thanks! That answers my question.
