Assign an IP Address to a Port

Assign an IP address to a port so that it acts as a routable VLAN (a brouter port) and supports IP routing.

Before you begin

  • Ensure routing (forwarding) is globally enabled.

  • Ensure the VLAN is configured.

  • If required, ensure the VRF instance exists.

About this task

After you configure the IP address, you cannot edit the IP address, and you can assign only one IP address to a brouter port.

You cannot assign an IP address to a brouter port that is a member of a routed VLAN. To assign an IP address to the brouter port, you must first remove the port from the routed VLAN.

If you want to assign a new IP address to a VLAN or brouter port that already has an IP address, first delete the existing IP address and then insert the new IP address.

The ability to create an IP interface in a disabled state in one step is available only using CLI.

Procedure

  1. In Device Physical View, select the port.
  2. In the navigation tree, expand Configuration > Edit > Port.
  3. Select IP.
  4. Select the IP Address tab.
  5. Select Insert.
  6. In the Insert IP Address dialog box, type the IP address, network mask, and VLAN ID.
  7. Select Insert.

IP Address Field Descriptions

Use the data in the following table to help use the IP Address tab.

Name

Description

Interface

Specifies the router interface.

  • The name of the VLAN followed by the VLAN designation identifies virtual router interfaces.

  • The slot and port number of the brouter port identifies brouter interfaces.

Ip Address

Specifies the IP address of the brouter interface on this port. You can define only one IP address on a given port interface.

Net Mask

Specifies the subnet mask of the brouter interface on this port. The mask is an IP address with all the network bits set to 1 and all the hosts bits set to 0.

Name

Specifies the name of the brouter interface. The value ranges from 0 to 64 characters.

BcastAddrFormat

Specifies the IP broadcast address format used on this interface.

ReasmMaxSize

Specifies the size of the largest IP packet which the interface can reassemble from fragmented incoming IP packets.

VlanId

Specifies the ID of the VLAN associated with the brouter port. This parameter is used to tag ports.

BrouterPort

Indicates whether this is a brouter port.

MacOffset

Specifies a number by which to offset the MAC address of the VLAN from the chassis MAC address. This ensures that each IP address has a different MACaddress.

VrfId

Specifies the associated VRF interface. The VrfId associates VLANs or brouter ports to a VRF after the creation of VLANs or brouter ports. VRF ID 0 is reserved for the Global Router.
