Accton Technology ES4710BD ARP configuration ARP Configuration Task Sequence, 17.3.2.2.1 Arp

ES4710BD 10 Slots L2/L3/L4 Chassis Switch

ES4710BD supports the configuration of proxy ARP for some applications. For instance, when an ARP request is received on the port, requesting an IP address in the same IP segment of the port but not the same physical network, if the port has enabled proxy ARP, the port would reply to the ARP with its own MAC address and forward the actual packets received. Enabling proxy ARP allows machines physically separated but of the same IP segment ignores the physical separation and communicate via proxy ARP interface as if in the same physical network.

17.3.2.1ARP Configuration Task Sequence

1.Configure static ARP

2.Configure proxy ARP

1. Configure static ARP

Command			Explanation
arp	<ip_address>	<mac_address>	Configures a static ARP entry; the “no arp
{[ethernet] <portName>}			<ip_address>” command deletes a static ARP
no arp <ip_address>			entry.
2. Configure proxy ARP
Command			Explanation
ip proxy-arp			Enables the proxy ARP function for Ethernet
no ip proxy-arp			ports: the “no ip proxy-arp”command
			disables the proxy ARP.

Command: arp <ip_address> <mac_address> {[ethernet] <portName>} no arp <ip_address>

Function: Configures a static ARP entry; the “no arp <ip_address>” command deletes a static ARP entry.

Parameters: <ip_address> is the IP address; <mac_address> is the MAC address; ethernet stands for Ethernet port; <portName> for the name of layer2 port.

Default: No static ARP entry is set by default.

Command mode: VLAN Interface Mode

Usage Guide: Static ARP entries can be configured in the switch.

Example: Configuring static ARP for interface VLAN1. Switch(Config-If-Vlan1)#arp 1.1.1.1 00-03-0f-f0-12-34 eth 1/2
