Global configuration mode
RUCKUS Layer 3 switches have a static ARP table, in addition to the regular ARP cache. The static ARP table contains entries that you configure.
Static entries are useful in cases where you want to pre-configure an entry for a device that is not connected to the Layer 3 switch, or you want to prevent a particular entry from aging out. The software removes a dynamic entry from the ARP cache if the ARP aging interval expires before the entry is refreshed. Static entries do not age out, regardless of whether the ICX device receives an ARP request from the device that has the entry address.
When the evi evi-instance
parameter is used, a static MAC-IP entry is created for the specified EVPN instance.
ARP suppression should be enabled for the EVPN instance using the arp-suppression
command.
The maximum number of static ARP entries you can configure depends on the software version running on the device.
Dynamic ARP Inspection must be enabled to use static ARP inspection entries that you have configured.
The
no form of the command removes the configured static ARP entry.
The following example creates a static ARP entry.
device# configure terminal device(config)# arp 10.53.4.2 0000.0054.2348 ethernet 1/1/2
