Configuring static-ARP on default VRFs
This command is used to configure static-ARP entries on default VRFs. The command is backward
compatible, and all static-ARP entries configured in previous releases are supported by the default
VRF.
Brocade(config)# arp 192.168.1.100 0000.2344.2441 eth 7/1
Syntax:[no] arp ip-address mac-address ethernet port
Configuring static-ARP on non-default VRFs
This command is used to configure static-ARP entries on a VRF interface. The VRF command does not
require an ARP index before configuring a static-ARP. The command is available in a VRF’s AF mode,
as shown below:
Brocade(config)#
Brocade(config)# vrf customer-1
Brocade(config-vrf-customer-1)# address-family ipv4
Brocade(config-vrf-customer-1-ipv4)# arp 1.1.1.1 0.0.1 ethernet 7/8
Brocade(config-vrf-customer-1-ipv4)# exit-address-family
Brocade(config-vrf-customer-1)# exit-vrf
Brocade(config)#
NOTE
For the FastIron 08.0.00a release the original command is backward compatible, but the output of the
configuration is saved in the new format. In the previous format of the command, static-ARP needed an
index. From FastIron 08.0.00a release onwards FastIron accepts the use of indexes as well as the new
command without the index.
Proxy ARP and Local Proxy ARP
Global Mode: proxy-arp
Interface Mode: local-proxy-arp
Proxy ARP allows a L3 switch to answer ARP requests from devices on one subnet on behalf of
devices in another network. Proxy ARP is a global configuration, and can be further configured per-
interface. Interface level configuration overrides the global configuration.
With proxy-arp configured, a router will not respond to ARP requests for IP addresses in the same
subnet as the incoming ports. local-proxy-arp permits the router to respond to ARP requests for IP
addresses within the same subnet and to forward all traffic between hosts in the subnet. local-proxy-
arp is an interface level configuration, and has no VRF related impact.
ARP rate-limiting
Global Mode: rate-limit-arp
Global and Interface Mode: ip arp-age
ARP rate-limiting configuration is a global value that applies to all the VRFs.
ARP age can be configured on the global level, and is configured on the L3 interface. Interface
configuration of ARP age timer, overrides the global mode ARP aging configuration.
