The ARP table does not include entries for devices that have no LAN inter-
faces.
IP Interfaces
To display a list of active IP interfaces, press [C] at the IP Status Displays Menu (or
[C], [F], [G], [C] from the Main Menu).
Information in this Display:
●
Name – identifier used in the IP Route Display. Each name is the interface
number preceded by the interface type, which is one of these:
fr Frame relay x X.25 en Ethernet
tr Token Ring lo Loopback
The loopback interface is added by the SmartSwitch 1800, and has a
number one greater than the highest configurable interface number
(to avoid a conflict)..
● MTU – Maximum Transmission Unit, the maximum size (in bytes) of the data
field that can be used to encapsulate an IP datagram for transmission over the
interface.
● Network – bit-wise AND of the IP Address and the Mask .
● IP Address – IP address of the local interface.
● Rem Address – IP address of the remote device.
● Flags : B = Broadcast.
L = Loopback.
M = Multicast.
P = Point-to-point.
U = Interface is operational.
0 = Unnumbered interface.
1 = Inverse ARP RTS (Request to Send).
2 = response from Inverse ARP RTS.
● Mask – Network mask, used during routing to determine the portion of the IP
address associated with the network.
Each entry is two lines on the screen, with the Mask on the second
line, under the associated IP Network .
If the screen is filled with information, you will be asked whether you want to display
more.
Pressing [F2] will display a screen of secondary addresses, with this information:
● IP# – interface number of the primary interface.
● Secondary addr – secondary IP address.
● Sec. broadcast – broadcast address configured for the secondary address.
● Sec. netmask – network mask configured for the secondary address.
