ARP Table Utilities Page
Activate the ARP Table Utilities page from the Protocol Configuration Page. Use the ARP Table
Utilities page to view and edit the ARP table defined by the IP Module. It allows up to 256 static
IP->MAC ARP entries.
Figure 14-21. ARP Table Utilities page
The ARP Table Utilities page contains the following options/fields:
Selection
Entry Description
Entry0001 – 0008
1 – 8 Defines up to 256 static ARP definitions on the IP Module. Use this table to
operate/view up to 8 of these definitions. An ARP definition is defined as:
1. Unicast IP Address
This IP Address is used as a lookup into the ARP table when the IP Module
needs to resolve a MAC or HDLC Address.
Restrictions:
IP Address must be on the same subnet as the Ethernet Interface.
IP Address must be a valid Unicast address (Not Multicast, broadcast, etc.)
2. MAC Address
The MAC Address defines the hardware destination MAC Address that is
used when an Ethernet packet is destined for an IP machine from the IP
Module.
Add IP to MAC ARP entry
M
Adds an IP to MAC ARP entry.
Delete ARP Entry
D
Deletes a Static ARP entry. Queries the user for the IP address of the ARP
entry to delete.
Display ARP Tbl
A
Displays the entire IP to MAC ARP table. Includes the Static as well as
dynamic ARP entries. Displays blocks of 10 ARP entries. Hit ‘Enter’ key to
display next 10 entries or ‘Escape’ to return to ARP Table Utilities page.
Flush ARP Table
F
Allows the entire ARP table to be removed. This is equivalent to performing
the standard UNIX command “arp –d” on each address reported in an “arp –
a” command. The command only flushes the dynamic ARP entries. The
static ARP entries will not be removed.
