IP Interfaces

You can configure IP interface in the control card. All the control operations such as the gateway resolution, tunnel health check, and NetFlow exporter SNMP requests are handled in the control card. Similarly, the ARP/NDP timer configuration is also moved to the control card.

You can configure the IP Interfaces for the following tunnels:

• GigaSMART tunnel - Refer to Configure IP Interfaces for GigaSMART Tunnels.

• Layer 2 Generic Routing Encapsulation (L2GRE) tunnel - Refer to About Layer 2 Generic Routing Encapsulation (L2GRE) Tunnels.

• Virtual Extensible LAN (VXLAN) tunnel - Refer to About Virtual Extensible LAN (VXLAN) Tunnels.

Configure IP Interface

Prerequisites

• Before you configure an IP interface, you must configure a network and a tool port.

• To configure IP interfaces for GigaSMART tunnels, you must create a GigaSMART group and a NetFlow exporter. Associate GigaSMART engines to theGigaSMART group.

To configure an IP interface:

1.

On the left navigation pane, click , and then select Physical > Nodes. Select the node for which you want to configure the IP interface.

2.

From the left navigation pane, go to Ports > IP Interfaces.

3.

In the IP Interfaces page, click New. The New IP Interface page appears.

4.

In the Alias and Description fields, enter a name and description for the IP interface.

5.

Click Port Editor. A quick port editor appears. You can enable the port for which you want to configure the IP interface. Click Save.

6.

From the Ports drop-down list, select the tool or the network port that you had enabled.

7.

Select the type as either IPv4 or IPv6.

8.

Enter the IP Address, IP Mask, and Gateway for the IP interface.

You can specify the subnet mask using either of the following formats:

o

netmask – For example, 255.255.255.248

o

mask length – For example, /29

Note:  For IPv6 interface configured on Generation 3 GigaSMART card (SMT-HC1-S), prefix length of 128 is not supported.

9.

Enter the MTU for the IP interface (100 - 9600 bytes). The MTU is fixed at 9600 for all network/tool ports on the following platforms:

■

Certified Traffic Aggregation White Box

■

GigaVUE‑HC1

■

GigaVUE‑HC3

■

GigaVUE‑TA25,GigaVUE‑TA25E, GigaVUE-TA100,GigaVUE‑TA200 and GigaVUE‑TA200E

RECOMMENDATION: Set the MTU to 9400 on all platforms.

10.

If you are configuring IP Interface for GigaSMART tunnels:

a.

From the GS Groups drop-down list, select theGigaSMART groups that you have configured.

Note:  You can associate multiple GigaSMART groups to the IP interface.

b.

From the Exporters drop-down list, select the NetFlow exports that you have created.

11.

Click Apply to configure the IP interface associated with a network or tool port and add it to the list of currently configured IP interfaces.

To edit the existing IP Interfaces, select the IP Interface and click Actions > Edit.

To delete the IP interfaces, select the IP Interface and click Actions > Delete.

IP Interface Statistics

To view the statistics such as the packets and bytes decapsulated on the IP interface:

1.

On the left navigation pane, click , and then select Physical > Nodes. Select the node for which you want to view the IP interface statistics.

2.

From the left navigation pane, go to Ports > IP Interfaces > Statistics. The IP Interface Statistics page appears.

To clear the statistics for a specific IP Interface, select the IP Interface and click Actions > Clear.

To clear all the statistics, select all the IP interfaces and click Actions > Clear All.

To export the IP Interface statistics, click Export.
