If no connectivity is established, the switch attempts to connect for threeminutes and then stops. Refer to Connectivity for more details on this process.After you enable the link between a switch and a hypervisor, the switch uses adiscovery mechanism to learn VMAC and VLAN information from the hypervisor.The discovery process also starts in the following conditions:• You enter the shutdown and no shutdown commands on a VSN-enabled port.The discovery process resumes on the individual port only, not on all enabledports.• You enter the disable and no disable commands in hypervisor configurationmode for a specified type of hypervisor connection. The discovery process isresumed on all enabled ports.• An update arrives from a hypervisor. The discovery process resumes on allVSN-enabled ports.In order for a switch to learn VLAN information from a hypervisor:• Incoming traffic must be received on the VSN-enabled ports.• There must be at least one VMAC configured on the hypervisor so that the VCAPtable can capture the VMAC entries for each VSN-enabled port.The following log messages are displayed when the discovery process is interruptedand when it starts again.Message 1Nov 28 11:34:19: %STKUNIT0-M:CP %VSNMGR-5-VSN_DISCOVERY_SUSPENDED:Hypervisor macs not seen on Te 0/25.
