Configuring IP parameters – Layer 3 Switches
PowerConnect(config)# interface ethernet 4
PowerConnect(config-if-e1000-4)# ip local-proxy-arp
Syntax: [no] ip local-proxy-arp
Use the no form of the command to disable Local Proxy ARP.
Creating static ARP entries
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 Dell PowerConnect
device receives an ARP request from the device that has the entry address.
NOTE
You cannot create static ARP entries on a Layer 2 Switch.
The maximum number of static ARP entries you can configure depends on the software version
running on the device. Refer to

To create a static ARP entry, enter a command such as the following.
PowerConnect(config)# arp 1 192.53.4.2 1245.7654.2348 ethernet 1/2
Syntax: arp <num> <ip-addr> <mac-addr> ethernet <port>
The <num> parameter specifies the entry number. You can specify a number from 1 up to the
maximum number of static entries allowed on the device.
The <ip-addr> parameter specifies the IP address of the device that has the MAC address of the
entry.
The <mac-addr> parameter specifies the MAC address of the entry.
The ethernet <port> command specifies the port number attached to the device that has the MAC
address of the entry. Specify the <port> variable in the following formats:

the static ARP table that are supported on a Layer 3 Switch. If you need to change the maximum
number of entries supported on a Layer 3 Switch, use the method described in this section.
NOTE
The basic procedure for changing the static ARP table size is the same as the procedure for changing
other configurable cache or table sizes. Refer to the section
