Assigning 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.

To configure a brouter port, assign an IP address to an IP policy-based single-port VLAN.

Before you begin

Ensure routing (forwarding) is globally enabled.
Ensure the VLAN is configured.
If required, ensure the VRF instance exists.

About this task

Important

After you configure the IP address, you cannot edit the IP address, and you can assign only one IP address to any router interface (brouter or virtual).

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.

Procedure

In Device Physical View, select the port.
In the navigation tree, expand the Configuration > Edit > Port folders.
Click IP.
Click the IP Address tab.
Click Insert.
In the Insert IP Address dialog box, type the IP address, network mask, and VLAN ID.
Click 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.
