Hi everyone,Do you know difference between Distributed Trunk and Vsf?
Distributed Trunking is a multi-chassis Link-aggregation technology, pure Layer2 and for 2 devices only.
VSF is a virtual stacking technology for data-plane (L2), but as well for control-plane (routing) and management plane (single IP address).
so can we says same platform mc-lag, aruba Distributed Trunk = nexus vpc = ArubaOSX VSX etc. ?
You can think about ArubaOS-CX VSX like a DT on steroids but you need to consider also that VSX is really ArubaOS-CX specific (and so it can be deployed only on Aruba 8400/8320 and 8325 starting from ArubaOS-CX 10.01 and newer) while DT Distributed Trunking refers to HP ProCurve, now Aruba, switch series (DT support some L3 features too...OSPF as example, it's not totally mutually exclusive with L3).
Thak you for answers. Could you check link is as below? is it Distributed Trunk(ARUBA), VSX(OS-X), VPC(Nexus), MCT(Brocade), M-lag(Huawei) etc. as platforms provide layer-2 redundancy and blocking stp loop?http://www.wikizero.biz/index.php?q=aHR0cHM6Ly9lbi53aWtpcGVkaWEub3JnL3dpa2kvTUMtTEFH

so when you say, Distributed Trunking is a multi-chassis Link-aggregation technology, pure Layer2 and for 2 devices only. This means, that each of the two switch(member) that act in the Distributed Trunk have their own e.g. Mangement IP?
on which device is the harp table kept? and Who gives the arp answer?
In DT it's the primary box that handles ARP responses, but the mac-tables are synchronized based on their learning.
This is largely correct, though there is some trunked port state data synchronized across the DT inter-switch link — other than that, both DT members operate as independent switches with their own routing, ARP, and MAC tables, configuration, etc.
