Deleting an ARP Table Entry {ARP Delete}
ARP (Address Resolution Protocol) is used to dynamically bind a high level IP address to a
low level physical hardware (MAC) address. ARP is limited to a single physical network that
supports hardware broadcasting. This procedure shows you how to delete an ARP table entry.
1.
From the Web Management Interface, click on
System
, then
ARP Delete .
The Delete
ARP Table Entries screen appears:
2. Enter the IP address of the entry you want to delete.
3. Click on the Delete button to delete this entry, or click on the Reset button if you want to
reset the “IP Address” value to its blank state.
Enabling the Bridge Mode Option {Bridge Mode}
Bridge Mode allows complete and unconditional access to devices on the subscriber side of the
Access Gateway. When the Bridge Mode option is enabled, the Access Gateway is effectively
transparent to the network in which it is located, allowing clusters of switches (especially
Cisco Systems switch clusters) to be managed using the STP (Spanning Tree Protocol), or any
other algorithm/protocol. The Access Gateway forwards any and all packets (except those
addressed to the Access Gateway network interface). The packets are unmodified and can be
forwarded in both directions. This
is a very useful feature when troubleshooting your entire
network as it allows administrators to effectively “remove” the Access Gateway from the
network without physically disconnecting the unit.
You can still manage the Access Gateway when Bridge Mode is enabled, but you have no
other functionality. If you enable the Bridge Mode option and then plug the Access Gateway
into a network, all you need to do is assign it routable IP addresses. You can then set up all
other features and disable the
Bridge Mode option whenever you want to start using the Access
Gateway in that network.
