Display neighbour table

  nstat

Description

Display all entries in the neighbour table. The output will show key information about each neighbour. For example:

  iPXE> nstat
  net0 IP 10.253.253.1 is Ethernet 02:00:69:50:58:45 (ARP)
  net0 IP 10.253.253.22 is Ethernet (incomplete) (ARP)
  net0 IPv6 fe80::69ff:fe50:5845 is Ethernet 02:00:69:50:58:45
  net0 IPv6 3ffe:302:11:2:0:69ff:fe50:5845 is Ethernet 02:00:69:50:58:45
  net0 IPv6 3ffe:302:11:2:0:2aff:6b84:321a is Ethernet (incomplete) (NDP)

In this example you can see that there are five neighbours:

  • IP address 10.253.253.1, resolved using ARP to Ethernet 02:00:69:50:58:45.
  • IP address 10.253.253.22, still attempting resolution using ARP.
  • IPv6 (link-local) address fe80::69ff:fe50:5845, resolved to Ethernet 02:00:69:50:58:45 without using a discovery protocol.
  • IPv6 (global) address 3ffe:302:11:2:0:69ff:fe50:5845, resolved to Ethernet 02:00:69:50:58:45 without using a discovery protocol.
  • IPv6 (global) address 3ffe:302:11:2:0:2aff:6b84:321a, still attempting resolution using NDP.
