To follow the progress of a package installation (or removal), use the show packages command.
Enabling VSN in a Hypervisor Session
To enable VSN on an interface and connect to hypervisors on network servers, follow these steps.
Important Information:
• VSN is only supported on standalone units; it is not supported in stacked congurations.
• VSN supports connections only with VMware and Xen hypervisors.
• You can dene up to eight hypervisor sessions on a switch.
• To connect with a VMware hypervisor running on an ESXi 5.0 server, congure the server’s rewall to allow connections only through
the management IP address. You can recongure the rewall by using the esxcli network firewall command to create a rule
set that allows the IP address of a Dell EMC Networking switch to pass the rewall. For detailed information, see How to Create
Custom Firewall Rules in ESXi 5.0.
• When you establish a VSN session with a Citrix Xen hypervisor (using the access command) that operates as a slave in a pool, the
connection establishes with the master. The entire pool retrieves the conguration and access information. If you remove the slave
from the pool and it operates as a standalone hypervisor, the VSN session is still active with the master. In this case, the pool retrieves
information and not the standalone hypervisor.
1 Enable VSN on an interface.
INTERFACE mode
vsn enable
By default, VSN is disabled on switch interfaces.
2 Specify the name of a hypervisor session and enter Hypervisor Conguration mode.
CONFIGURATION mode
hypervisor name
Enter up to 40 characters to dene the hypervisor session.
3 Dene the hypervisor type to which you want to connect.
HYPERVISOR mode
type {vmware | xen-citrix}
To display the currently supported hypervisor types, use the show hypervisor supported command.
4 Establish the connection between the switch and a hypervisor.
HYPERVISOR mode
access url username username password password
Where url is one of the following values:
• For a VMware hypervisor: https://[ip-address]/sdk/vimService username [name] password [password]
• For an Xen hypervisor: http://ip-address username [name] password [password]
• username name: Username to use for authentication on the server.
• password password: Password to use for authentication shown in clear text.
5 Set the mode for retrieving virtual server congurations and updating Dell EMC Networking OS settings on the switch.
HYPERVISOR mode
mode {check | config}
• check: Retrieves conguration information from the hypervisor and noties the system administrator of any conguration
changes. Enter the conguration changes manually on the switch.
