• ISATAP Robustness—Used to calculate the interval for the DNS or router
solicitation queries. The bigger the number, the more frequent the queries.
The default value is 3. The range is 1-20.
NOTE The ISATAP tunnel is not operational if the underlying IPv4 interface is
not in operation.
STEP 3 Click Apply. The tunnel is defined, and the switch is updated.
Defining IPv6 Neighbors Information
The IPv6 Neighbors Page
enables
configuring and viewing the list of IPv6
neighbors on the IPv6 interface. The IPv6 Neighbor table (also known as IPv6
Neighbor Discovery Cache) displays the MAC addresses of the IPv6 neighbors
that are in the same IPv6 subnet as the switch. This is used to verify the
reachability of this neighbor. This is the IPv6 equivalent of the IPv4 ARP table.
When the switch needs to communicate with its neighbors, the switch uses the
IPv6 Neighbor Table to determine the MAC addresses based on their the IPv6
addresses.
This page displays the neighbors that were automatically detected or manually
configured entries. Each entry displays to which interface the neighbor is
connected, the neighbor’s IPv6 and MAC addresses, the entry type (static or
dynamic), and the state of the neighbor.
To define IPv6 neighbors:
STEP 1 In Layer 2 mode, click Administration > Management Interface > IPv6
Neighbors.
In Layer 3 mode, click IP Configuration > Management and IP Interface > IPv6
Neighbors.
The IPv6 Neighbors Page opens.
STEP 2 Select a Clear Table option to clear some or all of IPv6 addresses in the IPv6
Neighbors Table.
•
Static Only
—Deletes the static IPv6 address entries.
•
Dynamic Only
—Deletes the dynamic IPv6 address entries.
•
All Dynamic & Static
—Deletes the static and dynamic address entries IPv6
address entries.
