250 CHAPTER 5: CONFIGURING WX SYSTEM AND ADMINISTRATIVE PARAMETERS
Configuring ARP The Address Resolution Protocol (ARP) table maps IP addresses to MAC
addresses. ARP is enabled by default on the WX and cannot be disabled.
An ARP entry is added to the table in one of the following ways:
■ Automatically by the WX. The WX adds a local entry for its own MAC
address and adds dynamic entries for addresses learned from traffic
received by the WX. When the WX receives an IP packet, the WX adds
the packet’s source MAC address and source IP address to the ARP
table.
■ By the system administrator. Using 3WXM, you can add permanent
entries to the ARP table.
In addition to adding permanent ARP entries, you can set the amount of
time unused dynamic entries remain in the table before they are
removed.
Adding ARP Entries
You can add permanent ARP entries to the ARP table. Permanent entries
do not age out and remain in the table even after the WX is rebooted.
To add a permanent ARP entry:
1 Do one of the following:
■ Open the WX Switch wizard, then select ARP under IP Services in the
organizer list of the System and Administrative page.
■ In the Organizer panel, select IP Services under a WX switch or
Domain Policies, then select Edit > Properties. The Modify IP Services
wizard appears. Click on ARP at the top of the wizard.
Here is an example of the ARP page in the WX Switch wizard.
