CHAPTER 48
IPv6 Neighbor Table
48.1 IPv6 Neighbor Table Overview
This chapter introduces the IPv6 neighbor table.
An IPv6 host is required to have a neighbor table. If there is an address to be resolved or verified,
the Switch sends out a neighbor solicitation message. When the Switch receives a neighbor
advertisement in response, it stores the neighbor’s link-layer address in the neighbor table. You can
also manually create a static IPv6 neighbor entry using the Basic Setting > IPv6 > IPv6
Configuration > IPv6 Neighbor Setup screen.
When the Switch needs to send a packet, it first consults other table to determine the next hop.
Once the next hop IPv6 address is known, the Switch looks into the neighbor table to get the link-
layer address and sends the packet when the neighbor is reachable. If the Switch cannot find an
entry in the neighbor table or the state for the neighbor is not reachable, it starts the address
resolution process. This helps reduce the number of IPv6 solicitation and advertisement messages.
48.2 Viewing the IPv6 Neighbor Table
Use this screen to view IPv6 neighbor information on the Switch. Click Management > IPv6
Neighbor Table in the navigation panel to display the screen as shown.

LABEL DESCRIPTION
Index This field displays the index number of each entry in the table.
Interface This field displays the ID number of the IPv6 interface on which the IPv6 address is created or
through which the neighboring device can be reached.
Neighbor
Address
This field displays the IPv6 address of the Switch or a neighboring device.
MAC This field displays the MAC address of the IPv6 interface on which the IPv6 address is
configured or the MAC address of the neighboring device.
