Optional Parameters

-AddressMaskReply

Gets IPv4 protocol configuration by the AddressMaskReply. AddressMaskReply indicates whether the computer will respond to ICMP Address mask packets. The acceptable values for this parameter are:

-- Enabled: IPv4 protocol configuration that contains the AddressMaskReply set to Enabled.

-- Disabled: IPv4 protocol configuration that contains the AddressMaskReply set to Disabled.

Type:AddressMaskReply[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-AsJob

ps_cimcommon_asjob

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227967 or Get-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227966 cmdlet. The default is the current session on the local computer.

Type:CimSession[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-DefaultHopLimit

Gets IPv4 protocol configuration by the DefaultHopLimit. DefaultHopLimit sets the default value for the CurrentHopLimit property in NetIPInterface. The CurrentHopLimit is the value that the IP interface writes in the TTL (Time to live) field in all outbound traffic. When forwarding a packet, routers are required to decrease the TTL by 1 and to discard the packet when the TTL is 0.

The default value is 128.

Type:UInt32[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-DhcpMediaSense

Gets IPv4 protocol configuration by the DHCPMediaSense. DHCP Media Sense provides a mechanism for the network interface card (NIC) to notify the protocol stack of media connect and disconnect events. These events trigger the DHCP client to take some action, such as attempting to renew a DHCP lease or removing routes related to a disconnected network. One application of Media Sense enables the network parameters on the notebook computer of a roaming user to automatically and transparently update without rebooting when the user moves from one location to another. The acceptable values for this parameter are:

-- Enabled: IPv4 protocol configuration that contains the DhcpMediaSense set to Enabled.

-- Disabled: IPv4 protocol configuration that contains the DhcpMediaSense set to Disabled.

The default value is Enabled.

Type:DhcpMediaSense[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-GroupForwardedFragments

Gets IPv4 protocol configuration by the GroupForwardedFragments. GroupForwardedFragments determines whether fragments should be collected into groups before being forwarded. The acceptable values for this parameter are:

-- Enabled: IPv4 protocol configuration that contains the GroupForwardedFragments set to Enabled.

-- Disabled: IPv4 protocol configuration that contains the GroupForwardedFragments set to Disabled.

The default value is disabled.

Type:GroupForwardedFragments[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-IGMPLevel

Gets IPv4 protocol configuration by the IGMPLevel. IGMPLevel determines the level of multicast support. IGMPLevel may determine (None) that multicast packets can neither be sent nor received; (SendOnly) the multicast packets can be sent but not received; or (All) multicast packets can be sent and received. The acceptable values for this parameter are:

-- None: IPv4 protocol configuration that contains the IGMPLevel set to None.

-- SendOnly: IPv4 protocol configuration that contains the IGMPLevel set to SendOnly.

-- All: IPv4 protocol configuration that contains the IGMPLevel set to All.

The default value is All.

Type:MldLevel[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-IGMPVersion

Gets IPv4 protocol configuration by the IGMPVersion number. The IGMPVersion shows the maximum IGMP version supported by the host.

Type:MldVersion[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-IcmpRedirects

Gets IPv4 protocol configuration by the IcmpRedirects. IcmpRedirects determine whether the path cache is updated in response to ICMP redirect packets. The acceptable values for this parameter are:

-- Enabled: IPv4 protocol configuration that contains the IcmpRedirects set to Enabled.

-- Disabled: IPv4 protocol configuration that contains the IcmpRedirects set to Disabled.

The default value is Enabled.

Type:IcmpRedirects[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-MediaSenseEventLog

Gets IPv4 protocol configuration by the MediaSenseEventLog. MediaSenseEventLog determines if the computer logs DHCP Media Sense events.

When Enabled, Media Sense events (connection/disconnection from the network) are logged in the event log for troubleshooting purposes. The acceptable values for this parameter are:

-- Enabled: IPv4 protocol configuration that contains the MediaSenseEventLog set to Enabled.

-- Disabled: IPv4 protocol configuration that contains the MediaSenseEventLog set to Disabled.

The default is Disabled.

Type:MediaSenseEventLog[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-MulticastForwarding

Gets IPv4 protocol configuration by the MulticastForwarding. MulticastForwarding determines whether multicast packets can be forwarded. The acceptable values for this parameter are:

-- Enabled: IPv4 protocol configuration that contains the MulticastForwarding set to Enabled.

-- Disabled: IPv4 protocol configuration that contains the MulticastForwarding set to Disabled.

The default is Disabled.

Type:MulticastForwarding[]
Position:Named
Default value:None

Type:UInt32[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-SourceRoutingBehavior

Gets IPv4 protocol configuration by the SourceRoutingBehavior. SourceRoutingBehavior determines the behavior for source routed packets. (DontForward) source routed packets can be received but not forwarded. (Drop) source routed packets will be dropped. (Forward) Per RFC 5095http://www.ietf.org/rfc/rfc5095.txt support for forwarding of source routed IPv6 packets has been removed, and the Forward setting now has the same effect as DontForward. The acceptable values for this parameter are:

-- DontForward: IPv4 protocol configuration that contains the SourceRoutingBehavior set to DontForward.

-- Drop: IPv4 protocol configuration that contains the SourceRoutingBehavior set to Drop.

The default value is DontForward.

Type:SourceRoutingBehavior[]
Position:Named
Default value:None
