Telnet Page 1

Page 1 displays the currently active ARP entries (up to a miximum of 40 entries = 20 lines, two entries per line) used by the Router. The ARP (or Address Resolution Protocol) table contains all entries for the Local LAN environment. ARP entries are refreshed every 2 minutes.

Each line contains two entries across, is updated every 1 second and has the following generic entry format

      IP             MAC     ST IF TTL
BBB.BBB.BBB.BBB CCCCCCCCCCCC DD EE FFF

Key

BBB.BBB is the IP address of a host on the local LAN in dotted decimal format.

CCCCC - is the 6 byte MAC (Media Access Control) address of the Ethernet destination displayed as 12 hexadecimal characters

DD - The ARP table entry status and may take one the following values

• OK = resolved entry
• WT = ARP request issued awaiting response
• WR = OK entry waiting a response to an ARP after timing out.
• BD = invalid entry

EE - defines the hardware interface unit as follows

• WarpOne
  • 10 = PCMCIA slot A
  • 11 = PCMCIA slot B,
  • 12 = PCMCIA slot C

• WarpTwo
  • 01 = LAN 0

FFF - is the ‘time to live’ (the time in seconds) before the ARP entry will expire from the ARP table and the Router will resend an ARP request to confirm the presence and MAC address of the host. Each entry in the ARP table is timed out every 120 seconds (2 minutes).

If all 40 entries have been displayed and there are additional un-displayed entries this is indicated by the text ‘….more entries’ after the last displayed ARP table entry.
