DESCRIPTION
The Get-NetIPv4Protocol cmdlet gets the global settings for IPv4 protocol configurations for the computer. If you
do not specify any parameters, the cmdlet gets the IPv4 protocol configuration settings for all network
connections for the computer. The cmdlet returns IPv4 protocol settings, such as the Internet Control Message
Protocol (ICMP) setting, the default hop limit, the neighbor cache limit, and the multicast configuration.
PARAMETERS
-AddressMaskReply []
Specifies an array of values for address mask reply. The cmdlet gets the IPv4 protocol configurations that
have these values. Address mask reply specifies how the computer responds to ICMP address mask packets. The
acceptable values for this parameter are:
-- Enabled. The computer responds to ICMP address mask packets.
-- Disabled. The computer does not respond to ICMP address mask packets.
Required? false
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-CimSession or Get-CimSession cmdlet. The default is the current session on the local
computer.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-DeadGatewayDetection []
Specifies an array of values for dead gateway detection. The cmdlet gets IPv4 protocol configurations that
have these values.
Dead gateway detection is a feature that identifies gateways that are not operating properly and switches the
computer to a new default gateway if available.
The acceptable values for this parameter are:
-- Enabled
-- Disabled
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-DefaultHopLimit []
Specifies an array of values for the default hop limit. The cmdlet gets the IPv4 protocol configurations that
have these values. The default hop limit is the default value for the CurrentHopLimit property in the IP
interface. The current hop limit is the value that the IP interface writes in the time-to-live (TTL) field in
all outbound traffic. When routers forward a packet, they decrement the hop limit by 1 and discard the packet
when the hop limit is 0.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-DhcpMediaSense []
Specifies an array of values for Media Sense. The cmdlet gets IPv4 protocol configurations that have these
values.
Media Sense provides a mechanism for the network adapter to notify the protocol stack of media connect and
disconnect events. These events trigger the DHCP client to take an action, such as attempting to renew a DHCP
lease or removing routes that are related to a disconnected network. When Media Sense is enabled, the network
parameters on the laptop of a roaming user are automatically and transparently updated without requiring a
restart when the user moves from one location to another. The acceptable values for this parameter are:
-- Enabled
-- Disabled
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-GroupForwardedFragments []
Specifies an array of values for group forwarded fragments. The cmdlet gets IPv4 protocol configurations that
have these values. Group forwarded fragments specifies whether the IP interface collects fragments into groups
before it forwards the fragments. The acceptable values for this parameter are:
-- Enabled. The IP interface collects IPv4 protocol fragments into groups before it forwards the fragments.
-- Disabled. The IP interface does not collect IPv4 protocol fragments into groups before it forwards the
fragments.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-IGMPLevel []
Specifies an array of values for the Internet Group Management Protocol (IGMP) level. The cmdlet gets IPv4
protocol configurations that have these values. The IGMP level specifies the level of multicast support. The
acceptable values for this parameter are:
-- None
-- SendOnly
-- All
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-IGMPVersion []
Specifies an array of the IGMP version numbers. The cmdlet gets IPv4 protocol configurations that have these
IGMP version numbers. The IGMP version is the maximum IGMP version supported by the host of IPv4 protocol
configuration.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-IcmpRedirects []
Specifies an array of values for ICMP redirects. The cmdlet gets IPv4 protocol configurations that have these
values. ICMP redirects specifies whether to update the path cache in response to ICMP redirect packets. The
acceptable values for this parameter are:
-- Enabled. The IP interface updates the path cache in response to ICMP redirect packets.
-- Disabled. The IP interface does not update the path cache in response to ICMP redirect packets.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-MediaSenseEventLog []
Specifies an array of values for Media Sense event log. The cmdlet gets IPv4 protocol configurations that have
these values. Media Sense event log specifies whether the computer logs DHCP Media Sense events. The
acceptable values for this parameter are:
-- Enabled. The IP interface logs DHCP Media Sense events in the event log for troubleshooting purposes.
-- Disabled. The IP interface does not log DHCP Media Sense events in the event log.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-MinimumMtu []
Specifies an array of values, in bytes, for network layer Maximum Transmission Unit (MTU). The cmdlet gets
settings that have the Mtu values that you specify.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-MulticastForwarding []
Specifies an array of values for multicast forwarding. The cmdlet gets IPv4 protocol configurations that have
these values. The acceptable values for this parameter are:
-- Enabled. The computer can forward multicast packets.
-- Disabled. The computer cannot forward multicast packets.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-NeighborCacheLimitEntries []
Specifies an array of values for the maximum number of neighbor cache entries. The cmdlet gets IPv4 protocol
configurations that have these values.
Required? false
Position? named
Default value none
Accept pipeline input? false
