Procedure 12-1: Address resolution protocol (ARP) routing

- Overview

This section allows the user to configure ARP and to view ARP information on the switch.

- Before you begin

Obtain the work instructions for this procedure.

Step

Perform the following to configure ARP and/or to view ARP information on the switch.

 
1

Log in to the VLNC6x being provisioned.


2

From the Navigation menu, select Routing → ARP → ARP Create. Enter the required parameters, then click Submit.

Equivalent CLI command: From the Global Config mode, enter arp <ipaddress> <macaddress>.

Parameters:

  • IP Address: The IP address of a device on a subnet attached to an existing routing interface. It is an IPv4 address.

  • MAC Address: The unicast MAC address for the device. It contains six two-digit hexadecimal numbers that are separated by colons.


3

From the Navigation menu, select Routing → ARP → ARP Table Configuration to configure and display the ARP information. Enter the required parameters, then click Submit.

A list of all ARP entries in the ARP cache are displayed at the bottom of the screen.

For the equivalent CLI commands and descriptions, see ARP table parameters , ARP table entries, and Address Resolution Protocol (ARP) commands under Routing commands in the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide.

ARP table parameters

Parameter

Description

CLI command

Age Time (secs)

The ARP entry ageout time in seconds. Valid values: an integer value in the range of 15 to 21600 seconds. The default is 1200.

arp timeout <seconds>

Response Time (secs)

This is the ARP request response timeout time in seconds. Valid values: an integer value in the range of 1-10 seconds. The default value is 1.

arp resptime <seconds>

Retries

The maximum number of retries. Valid values: an integer value in the range of 0 -100. The default value is 4. The value "100" means the retry will be sent forever until the request is resolved.

arp retries <count>

Cache Size

The number of entries in the cache. Valid values: an integer value in the range of 256 - 1920. The default value is 1920.

arp cachesize <cache-size>

Dynamic Renew

Enables/disables the ARP component to automatically renew dynamic ARP entries when they age out. Valid values: Enable (default) or Disable.

arp dynamicrenew

Total Entry Count

This is a display-only field. Total number of ARP entries.

show arp

Peak Total Entries

This is a display-only field.

show arp

Active Static Entries

This is a display-only field.

show arp

Configured Static Entries

This is a display-only field.

show arp

Maximum Static Entries

This is a display-only field.

show arp

Remove From Table Entry

This is a drop-down list containing:

  • All Dynamic Entries

  • All Dynamic and Gateway Entries

  • Specific Dynamic/Gateway Entry

  • Specific Static Entry

  • None

clear arp-cache - Use to remove all dynamic entries from the ARP cache.

clear arp-cache gateway - Use to remove all dynamic/gateway entries from the ARP cache.

Remove IP Address

This is the IP address for a specific Dynamic/ Gateway, or Static entry. It is an IPv4 address format. If the "Remove From Table Entry" field is "Specific dynamic/Gateway Entry" or "Specific Static Entry" (see above), then this is a required field. Otherwise, this field does not display.

arp purge <ipaddr> - Use to remove the specified IP address from the ARP cache. Only entries of type dynamic or gateway are affected by this command.

ARP table entries

Parameter

Description

CLI command

IP Address

show arp

MAC Address

The MAC address of the ARP entry. It contains six 2- digit hexadecimal numbers separated by colons ":".

show arp

Interface

The interface of the ARP entry.

show arp

Type

Type of the ARP entry. Valid values: Local or Static.

show arp
