UDT Juniper Switches Sub-Interfaces

UDT needs the sub-interfaces of access ports, not the physical ports -- the client MAC address and VLAN information is associated with the subinterface only.

i.e. ge-0/0/0.0

Interesting.  So will things like the physical port attributes be lost then if we do not monitor them - ie speed / duplex / description?

I really think sub-interfaces should not be counted as separate interfaces for licensing purposes - it just make the whole configuration harder to manage.

yep... we have the unlimited licence count versions so not such a big deal for me here.

I manage the physical interfaces in NPM, and the subinterface ports in UDT.

we only manage the uplink and trunk interfaces, access ports are only added to UDT

Other gotchas: unconfigured interfaces may not appear in the MIB; so you end up with a 2200-48P only having 13 interfaces in UDT :-(

in this case one should really blame Juniper for their less than great SNMP support; it might be good if Solarwinds would merge the physical interface and the unit0 interfaces together, but the stats on the two are not quite the same and I am loathe to idea-ate things I have not spent some time thinking about the deeper implications of.

Well I think it would be really nice if the sub-interface at least showed up under the physical interface in Orion.  Oh, and if they could be ordered according to numerical value instead of 1,10,11,12,...2,20,21,22 that would go a long way in making it easier to use.
