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, see 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.
• Enter the disable and no disable commands in Hypervisor Configuration mode, for a specified type of hypervisor connection.
The discovery process resumes on all enabled ports.
• An update arrives from a hypervisor. The discovery process resumes on all VSN-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 VCAP table can capture the VMAC entries for each VSN-
enabled port.
The following log messages display when the discovery process is interrupted and when it starts again:
Nov 28 11:34:19: %STKUNIT0-M:CP %VSNMGR-5-VSN_DISCOVERY_SUSPENDED:
Hypervisor macs not seen on Te 0/25. Discovery suspended.
Nov 28 11:40:36: %STKUNIT0-M:CP %VSNMGR-5-VSN_DISCOVERY_RESUMED: Detected
config change in Hypervisor. Discovery of Hypervisor macs resumed on Te 0/25.
