Removes an association between a Location Information Server (LIS) port and a location. This association is used in an Enhanced 911 (E9-1-1) Enterprise Voice implementation to notify an emergency services operator of the caller’s location.
Syntax
Remove-CsLisPort -ChassisID <String> -PortID <String> -PortIDSubType <InterfaceAlias | InterfaceName | LocallyAssigned> [-Confirm [<SwitchParameter>]] [-WhatIf [<SwitchParameter>]] |
Parameters
| Parameter | Required | Type | Description |
|---|---|---|---|
|
ChassisID |
Required |
String |
The MAC address of the port switch. This value will be in the form nn-nn-nn-nn-nn-nn, such as 12-34-56-78-90-ab. |
|
PortID |
Required |
String |
The ID of the port you want to remove. |
|
PortIDSubType |
Required |
PortIDSubType |
The subtype of the port you want to remove. This value can be entered as a numeric value or a string, but it must be a valid subtype. Valid subtypes are: 1: InterfaceAlias 5: InterfaceName 7: LocallyAssigned |
|
Confirm |
Optional |
SwitchParameter |
Prompts you for confirmation before executing the command. |
|
WhatIf |
Optional |
SwitchParameter |
Describes what would happen if you executed the command without actually executing the command. |
Detailed Description
Enhanced 911 allows an emergency operator to identify the location of a caller without having to ask the caller for that information. In the case where a caller is calling from a Voice over IP (VoIP) connection that information must be extracted based on various connection factors. The VoIP administrator must configure a location map (called a wiremap) that will determine a caller’s location. This cmdlet removes an association between a physical location and a port through which calls will be routed.
Removing a port location will not remove the actual location or the port switch, it removes only the port. To remove the location call the Remove-CsLisLocation cmdlet; to remove the switch call the Remove-CsLisSwitch cmdlet.
If you attempt to remove a port that does not exist, no action will be taken and you will not receive an error or a warning message.
Return Types
This cmdlet does not return a value. It removes an object of type System.Management.Automation.PSCustomObject.
Examples
-------------------------- Example 1 --------------------------
 Copy Code |
|
|---|---|
Remove-CsLisPort -ChassisID 99-99-99-99-99-99 -PortID 4200 -PortIDSubType 1 |
|
Example 1 removes the LIS port location with the MAC address (ChassisID) 99-99-99-99-99-99, the PortID 4200, and the PortIDSubType 1. (Note that a value of 1 for PortIDSubType translates into a value of InterfaceAlias. This parameter and value could also have been entered like this: -PortIDSubType InterfaceAlias)
If this port was associated with a location, that location will not be removed, only the port will be removed from the location mapping.
-------------------------- Example 2 --------------------------
| Copy Code |
|
|---|---|
Get-CsLisPort | Where-Object {$_.HouseNumber -eq ""} | Remove-CsLisPort
|
|
This example removes all port locations that do not have a house number. The example begins with a call to the Get-CsLisPort cmdlet, which returns a collection of all port locations. This collection is piped to the Where-Object cmdlet, which finds the items in that collection that have a HouseNumber property that is empty; in other words, a HouseNumber that is equal to (-eq) an empty string (“”). Finally, we pipe this collection of port locations that don’t have house numbers to the Remove-CsLisPort cmdlet, which removes everything in that collection.
Note that, as in example 1, no locations are removed from the location database, only the ports that reference those locations are removed. In this case that means there will be invalid locations (they’re invalid because HouseNumber is a required property for a location) in the location database that should also be removed. You can remove locations by calling the Remove-CsLisLocation cmdlet.
