Configure an IPv6 Interface

You must configure an IPv6 interface for a VLAN or brouter port before you can assign an IPv6 address to the interface.

Before you begin

  • You must configure a VLAN before you can give the VLAN an interface identifier or an IPv6 address. The switch supports port-based, protocol-based, and MAC-source-based VLANs.

    For information about how to configure VLANs, see VLAN Configuration using EDM.

  • Change the VRF instance as required to configure an IPv6 interface on a specific VRF instance. Not all parameters are configurable on non-default VRFs.

About this task

You can also configure an IPv6 interface for a brouter port through the Edit > Port > IPv6 navigation path, and for a VLAN through the VLAN > VLANs > Basic > IPv6 navigation path. This procedure uses the main IPv6 navigation path where you can create both types of interfaces.

Procedure

  1. In the navigation pane, expand the Configuration > IPv6 folders.
  2. Select IPv6.
  3. Select the Interfaces tab.
  4. Select Insert.
  5. In the Interface field, select Port or VLAN.
  6. Select a port or VLAN.
  7. Select OK.
  8. Select the AdminStatus field to activate the interface.
  9. Configure the remaining parameters as required.
  10. Select Insert.
  11. Select Apply.

Interfaces Field Descriptions

Use the data in the following table to use the Interfaces tab.

Name

Description

Interface

Specifies the port or VLAN.

Identifier

Shows the IPv6 address interface identifiers. This value is a binary string of up to 8 octets in network byte-order.

IdentifierLength

Shows the length of the identifier, in bits.

Descr

Specifies a description of the interface. The network management system also configures this string.

VlanId

Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1.

This value corresponds to the lower 12 bits of the IEEE 802.1Q VLAN tag.

Type

Shows the interface type.

ReasmMaxSize(MTU)

Specifies the maximum size of the MTU of this IPv6 interface. This value must be the same for all the IP addresses defined on this interface. The default value is 1500.

Different hardware platforms support different MTU values.

PhysAddress

Specifies the media-dependent physical address. For Ethernet, this is a MAC address.

AdminStatus

Specifies if IPv6 is active on this interface. The default is false (disabled).

OperStatus

Specifies the current operational status of the interface.

ReachableTime

Specifies the time, in milliseconds, that a neighbor is considered reachable after receiving a reachability confirmation. The default is 30000.

RetransmitTimer

Specifies the time, in milliseconds, between retransmissions of neighbor solicitation messages to a neighbor when resolving the address, or when probing the reachability of a neighbor. The default is 1000.

CurHopLimit

Specifies the current hop limit field sent in router advertisements from this interface. The value must be the current diameter of the Internet. A value of zero indicates that the advertisement does not specify a value for CurHopLimit. The default is 64.

MulticastAdminStatus

The option to select MulticastAdminStatus is disabled. You cannot configure the administrative status for multicast in this context.

MacOffset

Requests a particular MAC for an IPv6 VLAN.

You can specify a MAC offset when you configure IPv6 on a VLAN, or the system can assign a MAC address from within the available range.

Different hardware platforms support different MAC offset ranges.

RSMLTEnable

Shows whether RSMLT is enabled on the interface.

The default value is disabled (false).

ProcessRedirect

Shows whether ND Redirect messages processing is enabled or disabled on this interface.

The default value is disabled (false).
