Configuring ARP in Gaia Clish

Important - On Scalable Platforms (ElasticXL, Maestro, and Chassis), you must run the applicable commands in Gaia gClish of the applicable Security Group.

Note - For Scalable Platforms (Maestro and Chassis), also refer to the "asg_arp" command in Gaia gClish. See the R82 Scalable Platforms Administration Guide.

Syntax

add arp static ipv4-address <IPv4 Address> macaddress <MAC Address> 

delete arp
      dynamic all
      static ipv4-address <IPv4 Address>
 
set arp table
      validity-timeout <Seconds>
      cache-size <Number of Entries>
 
show arp
      dynamic all
      static all
      table validity-timeout
      table cache-size

Important - After you add, configure, or delete features, run the "save config" command to save the settings permanently. Scalable Platforms save the changes automatically.

Parameters

Parameter

Description

static

Configures static ARP entries.

dynamic

Configures dynamic ARP entries.

ipv4-address <IPv4 Address>

Configures IPv4 Address for a static ARP entry.

  • Range: Dotted-quad ([0-255].[0-255].[0-255].[0-255])

  • Default: No default value

macaddress

Configures the hardware MAC address (six hexadecimal octets separated by colons) for a static ARP entry.

  • Range: 00:00:00:00:00:00 - FF:FF:FF:FF:FF:FF

  • Default: No default value

table validity-timeout <Seconds>

Configures the time, in seconds, resolved dynamic ARP entries in the ARP cache table are checked for validity.

If the entry is not referred to and is not used by traffic before this time elapses, the dynamic ARP entry is marked as STALE.

Otherwise, an ARP Request will be sent to verify the MAC address.

  • Range: 60 - 86400 seconds (24 hours)

  • Default: 60 seconds

table cache-size <Number of Entries>

Configures the maximum number of entries in the ARP cache table.

  • Range: 1024 - 131072

  • Default: 4096

Note - Make sure to configure a value large enough to accommodate at least 100 dynamic ARP entries, in addition to the maximum number of static ARP entries.
