Netsh commands for routing IP relay

  • The following entries provide details for each command.

dump

Displays the Dynamic Host Configuration Protocol (DHCP) Relay Agent configuration of a remote access server in script form.

Syntax

dump

Remarks

  • You can dump the contents of the current configuration to a file that can be used to restore altered configuration settings.

Example

The following commands save the current configuration as a script in the c:\test\relaycfg.dmp file.

  • From the command prompt:

    netsh routing ip relay dump > c:\test\relaycfg.dmp

  • From the netsh routing ip relay context prompt:

    set file open c:\test\relaycfg.dmp

    dump

    set file close

You can use the netsh exec command to run the script created by the netsh dump command.

add dhcpserver

Syntax

add dhcpserver

[ server = ] IPAddress

Parameters

  • [ server = ] IPAddress
    Required. Specifies, by IPv4 address, the DHCP server you want to add.

Example

To add a DHCP server with the IPv4 address of 10.0.0.1 to the global list of DHCP servers, type:

add dhcpserver 10.0.0.1

add interface

Enables the DHCPv4 Relay Agent on the specified interface.

Syntax

add interface

[ name = ] InterfaceName

Parameters

  • [ name = ] InterfaceName
    Required. Specifies, by name, the interface on which you want to enable the DHCPv4 Relay Agent. The InterfaceName parameter must match the name of the interface as specified in Network Connections. If InterfaceName contains spaces, use quotation marks around the text (for example, "Interface Name").

Example

To enable DHCPv4 Relay Agent on the Local Area Connection interface, type:

add interface "Local Area Connection"

delete interface

Disables DHCPv4 Relay Agent on the specified interface.

Syntax

delete interface

[ name = ] InterfaceName

Parameters

  • [ name = ] InterfaceName
    Required. Specifies, by name, the interface on which you want to disable the DHCPv4 Relay Agent. The InterfaceName parameter must match the name of the interface as specified in Network Connections. If InterfaceName contains spaces, use quotation marks around the text (for example, "Interface Name").

Example

To disable the DHCPv4 Relay Agent on the Local Area Connection interface, type:

delete interface "Local Area Connection"

delete dhcpserver

Removes a DHCPv4 server from the list of DHCP servers whose messages will be forwarded by DHCP Relay Agent.

Syntax

delete dhcpserver

[ server = ] IPAddress

Parameters

  • [ server = ] IPAddress
    Required. Specifies, by IPv4 address, the DHCP server to be deleted.

Example

To delete a DHCP server with the IPv4 address of 10.0.0.1 from the global list of DHCP servers, type:

delete dhcpserver 10.0.0.1

set global

Sets global parameters for the DHCPv4 Relay Agent configuration.

Syntax

set global

[ loglevel = ] { none | error | warn | info }

Parameters

  • [ loglevel = ] { none | error | warn | info }
    Required. Specifies which DHCPv4 Relay Agent events should be logged.

    • none specifies that no events related to DHCP Relay Agent should be logged.

    • error specifies that only errors related to DHCP Relay Agent should be logged.

    • warn specifies that both errors and warnings related to DHCP Relay Agent should be logged.

    • info specifies that all events related to DHCP Relay Agent should be logged.

Example

To configure global parameters for DHCP Relay Agent to not log events, type:

set global loglevel=none

set interface

Updates the DHCPv4 Relay Agent configuration on an interface.

Syntax

set interface

[ name = ] InterfaceName

[ relaymode = ] { enable | disable }

[ [ maxhop = ] Integer ]

[ [ minsecs = ] Integer ]

Parameters

  • [ name = ] InterfaceName
    Required. Specifies, by name, the interface on which you want to update the configuration of the DHCPv4 Relay Agent. The InterfaceName parameter must match the name of the interface as specified in Network Connections. If InterfaceName contains spaces, use quotation marks around the text (for example, "Interface Name").
  • [ relaymode = ] { enable | disable }
    Required. Specifies whether the DHCPv4 Relay Agent is enabled or disabled.
  • [ [ maxhop = ] Integer ]
    Specifies the number of hops a DHCPv4 packet can make before it is dropped and no longer relayed.
  • [ [ minsecs = ] Integer ]
    Specifies the minimum number of seconds from boot time that must appear in a DHCPv4 packet before it is sent to a DHCP server in the list of servers whose messages will be forwarded by the DHCPv4 Relay Agent.

Example

To update the DHCPv4 Relay Agent configuration on the interface named Local Area Connection with a maximum hop count of 16 and a value of 4 seconds for the minimum seconds from boot time, type:

set interface name="Local Area Connection" enable 16 4
