자세한 설명

The Get-NetNeighbor cmdlet gets neighbor cache entries. The cmdlet returns information about IP addresses and link-layer addresses for the neighbor cache entries.

The neighbor cache maintains information for each on-link neighbor, including the IP address and the associated link-layer address. In IPv4, the neighbor cache is commonly known as the Address Resolution Protocol (ARP) cache.

-LinkLayerAddress<String[]>

Specifies an array of link-layer addresses of the neighbor cache entry. The cmdlet gets neighbor cache entries that have the link-layer addresses you specify.

The link-layer address is also called the media access control (MAC) address. A link-layer address that uses IPv4 address syntax is a tunnel technology that encapsulates packets over an IPv4 tunnel, such as Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) or Teredo. A link-layer address of all zeroes indicates that the neighbor is unreachable and the neighbor cache entry does not have a link-layer address entry. An empty link-layer address indicates that the link layer does not use link-layer addresses, such as on a loopback interface.

-PolicyStore<String>

Specifies a PolicyStore value. The cmdlet gets neighbor cache entries that have the PolicyStore value you specify. 이 매개 변수에 허용되는 값은 다음과 같습니다.

-- ActiveStore. The IP address information is valid.
-- PersistentStore. The computer saves IP address information across restarts. When the computer restarts, it copies the saved settings to the ActiveStore.

-State<State[]>

Specifies an arrary of states of neighbor cache entries. The cmdlet gets neighbor cache entries that have the state you specify. The neighbor cache contains information maintained by Neighbor Unreachability Detection. Neighbor Unreachability Detection for IPv4 tracks the reachable state of IPv4 nodes in the IPv4 route cache. 이 매개 변수에 허용되는 값은 다음과 같습니다.

-- Unreachable. The IP address is unreachable.
-- Incomplete. Address resolution is in progress and Neighbor Unreachability Detection has not determined the link-layer address of the neighbor.
-- Probe. The neighbor is no longer known to be reachable, and Neighbor Unreachability Detection is sending unicast Neighbor Solicitation probes to verify reachability.
-- Delay. The neighbor is no longer known to be reachable, and traffic was recently sent to the neighbor. Neighbor Unreachability Detection does not probe the neighbor immediately. Neighbor Unreachability Detection delays sending probes for a short time so that the upper layer protocols can provide reachability confirmation.
-- Stale. The neighbor is no longer known to be reachable. and Until traffic is sent to the neighbor, Neighbor Unreachability Detection makes no attempt to verify its reachability.
-- Reachable. The neighbor is known to have been reachable recently, within the last minute.
-- Permanent. The neighbor is statically provisioned and will not expire unless you remove it through configuration.
-- Maximum. A maximum value for testing purposes.

-ThrottleLimit<Int32>

Cmdlet을 실행하도록 설정할 수 있는 동시 작업의 최대 수를 지정합니다. 이 매개 변수를 생략하거나 값으로 0 을 입력하면 Windows PowerShell®은 컴퓨터에서 실행 중인 CIM cmdlet의 수에 따라 cmdlet에 대한 최적의 스로틀 제한을 계산합니다. 스로틀 제한은 현재 cmdlet에만 적용되고, 세션이나 컴퓨터에는 적용되지 않습니다.

입력

입력 형식은 cmdlet으로 파이프할 수 있는 개체의 형식입니다.

  • None

출력

출력 형식은 cmdlet 실행 시 출력되는 개체의 형식입니다.

  • Microsoft.Management.Infrastructure.CimInstance#root\StandardCimv2\MSFT_NetNeighbor

    Microsoft.Management.Infrastructure.CimInstance 개체는 WMI(Windows Management Instrumentation) 개체를 표시하는 래퍼 클래스입니다. 파운드 기호(#) 뒤의 경로는 기본 WMI 개체에 대한 네임 스페이스 및 클래스 이름을 제공합니다.


Example 1: Get all neighbor cache entries

This command gets all the neighbor cache entries. The default output for the cmdlet does not include all properties of the NetNeighbor object.


PS C:\> Get-NetNeighbor

Example 2: Output all properties for neighbor cache entries

This command gets all the neighbor cache entries. The command uses the Format-List cmdlet to display all the properties in the output in the form of a table. For more information, type Get-Help Format-Table.


PS C:\> Get-NetNeighbor | Format-List –Property *

Example 3: Get neighbor cache entries that have an IPv6 address

This command gets information about the neighbor cache for neighbors that have an IPv6 address.


PS C:\> Get-NetNeighbor –AddressFamily IPv6

Example 4: Get network adapters that have reachable neighbors

This command gets a NetNeighbor object that contains neighbor cache entries that are reachable. The command passes the NetNeighbor object to the Get-NetAdapter cmdlet by using the pipeline operator. The Get-NetAdapter cmdlet gets the network adapters that have the interface index number for the network neighbors stored the NetNeighbor object.


PS C:\> Get-NetNeighbor –State Reachable | Get-NetAdapter
