VDP uses ECP as transport for VDP TLVs. An ECP frame may contain multiple VDP TLVs. Each VDP TLVs contains a mode, typeid, version, instanceid, mac and vlan for a VSI.ARGUMENTSenableTx Enables or disables VDP mode shows or sets modes for VSIs with the following parameters: <mode> mode (0=preassociate, 1=preassociate with RR, 2=associate, 3=deassociate) <mgrid> manager (database) id <typeid> VSI type id <version> VSI type id version <instanceid> VSI instance id <format> VDP filter info format <mac> VSI mac address <vlan> VSI vlan id role shows or sets the role of the local machine to act as either station (default) or bridge. Theory of Operation The VDP protocol is used to pre-associate, associate or deassociate VSIs to and adjacent switch. Information about the VSIs is formatted into VDP TLVs which are then handed to ECP for lower-level transport. Each ECP frame may contain multiple VDP TLVs. Two ways to receive VSI information exist in llpdad: via netlink or with lldptool. netlink is used by libvirt to communicate VSIs to lld- pad. lldptool can be used to associate/deassociate VSIs from the command line. This is especially helpful for testing purposes. EXAMPLE & USAGE Display if vdp is enabled on eth8 lldptool -t -i eth8 -V vdp -c enableTx Enable vdp on eth8 lldptool -T -i eth8 -V vdp -c enableTx=yes Display the currently configured VSIs for eth8 lldptool -t -i eth8 -V vdp -c mode Associate a VSI on eth8 lldptool -T -i eth8 -V vdp -c mode=2,12,1193046,1,fa9b7fff-b0a0-4893-8e0e-beef4ff18f8f,2,52:54:00:C7:3E:CE,3 Display the locally configured role for VDP on eth8 lldptool -t -i eth8 -V vdp -c role Set the local role for VDP on eth8 lldptool -T -i eth8 -V vdp -c role=bridgeSOURCEo IEEE 802.1Qbg (http://www.ieee802.org/1/pages/802.1bg.html)NOTESCurrently the code in lldpad reflects draft 0 of the upcoming standard. ECP/VDP TLVs on the wire can be decoded with wireshark > v1.8.SEE ALSOlldptool-evb(8), lldptool(8), lldpad(8)AUTHORJens Osterkamp open-lldp February 2010 lldptool(8)
