Changing VSN Settings
After you enable VSN on an interface and enable a hypervisor session that connects to hypervisors on
network servers, you can change the mode setting when the session is active.
You cannot, however, change the type and access settings if the session is active.
To change these settings, follow these steps.
1. In Hypervisor Configuration mode, stop the session by entering the disable command.
2. Enter the no type {vmware | xen-citrix} or no access url username username
password password command to remove a configured setting.
3. Enter the type {vmware | xen-citrix} or access url username username password
password command to configure a new setting.
Discovery
The discovery process starts after you enter the no disable command on the interface and ends in 10
minutes after connectivity establishes between the switch and the hypervisor. If no connectivity
establishes, the switch attempts to connect for three minutes and then stops.
For more information about this process, refer to Connectivity.
After you enable the link between a switch and a hypervisor, the switch uses a discovery mechanism to
learn VMAC and VLAN information from the hypervisor. The discovery process also starts in the following
conditions:
• Enter the shutdown and no shutdown commands on a VSN-enabled port. The discovery process
resumes on the individual port only, not on all enabled ports.
