Measures reported by PANvSwitchTest

The virtual switch created by PAN Manager functions just like a physical switch. A vSwitch is designated for either network (Ethernet) or storage traffic (Fibre Channel), but cannot be used for both. PAN Manager supports two types of Ethernet vSwitches:

  • Uplinked vSwitch: The Ethernet vSwitch associated with a network uplink, which provides external connectivity. An uplinked Ethernet vSwitch must have a VLAN ID configured on the premises network and can be enabled for link dependency.
  • Non-uplinked vSwitch: The Ethernet vSwitch that provides internal connectivity between pServers. A non-uplinked Ethernet vSwitch should use a VLAN ID already added to PAN Manager.

Normally pServers are connected to the pNodes using vSwitches. This test auto-discovers the vSwitch in a PAN network and reports the following:

  • The type of this vSwitch;
  • What is the uplink status of this vSwitch? and whether the link dependancy capability is enabled for this vSwitch?
  • How many LPANS are allocated to each vSwitch? and
  • How many pServers are connected through the vSwitch and what is the VLAN ID of each connection?

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Switch_type Indicates the type of this vSwitch.   This measure reports Ethernet or Fibre Channel based on the type of the vSwitch.

The numeric values that correspond to the above-mentioned types are as follows:

Type Numeric Value
Ethernet 1
Fibre Channel 2

Note:

By default, this measure reports the above-mentioned Types while indicating the type of the vSwitch. However, the graph of this measure will be represented using the corresponding numeric equivalents i.e., 1 or 2.

IsAttached_uplink Indicates whether/not this vSwitch is uplinked.   An uplink is a collection of one or more ports bound together into a single entity that connects to external switches for either Ethernet (network) or Fibre Channel (storage) connectivity.

This measure reports a value Uplinked if this vSwitch is uplinked and a value Not uplinked if otherwise.

The numeric values that correspond to the above-mentioned values are as follows:

Measure Value Numeric Value
Uplinked 1
Not uplinked 0

Note:

By default, this measure reports the above-mentioned Measure Values while indicating whether/not this vSwitch is uplinked. However, the graph of this measure will be represented using the corresponding numeric equivalents i.e., 0 or 1.

The detailed diagnosis capability of this measure if enabled, lists out the NAME OF THE UPLINK to which this vSwitch is uplinked.

Link_dependancy Indicates whether/not the link dependancy is enabled on this vSwitch.   PAN Manager supports link dependency, a feature of a physical switch (usually an edge switch) that reflects the state of the switch's uplink port(s) to the downlink ports. In PAN Manager, you enable/disable link dependency on a vSwitch. If a disruption in network connectivity that is external to the PAN occurs, the bonding/teaming software in the pServer's operating system redirects network traffic over the pServer's other available path to the external network.

This measure reports a value On if link dependancy is enabled on this vSwitch and a value Off if the link dependancy is disabled.

The numeric values that correspond to the above-mentioned measure values are as follows:

Measure Value Numeric Value
On 1
Off 0

Note:

By default, this measure reports the above-mentioned Measure Values while indicating whether/not the link dependancy is enabled on this vSwitch. However, the graph of this measure will be represented using the corresponding numeric equivalents i.e., 0 or 1.
Vlan_id Indicates the VLAN ID through which this vSwitch is connected to the pServer. Number  
Alloc_lpans Indicates the total number of LPANS to which this vSwitch is allocated to. Number The detailed diagnosis capability of this measure, if enabled lists out the NAME OF THE LPANs to which this vSwitch is allocated to.
Assign_pserver Indicates the total number of pServers that are connected through this vSwitch. Number The detailed diagnosis capability of this measure, if enabled lists out the NAME OF THE LPAN, the PSERVER NAME and the VSWITCH TYPE.
