Configuring A Static Ipv6 Route; Configuring Ipv6 Tcp Properties - 3Com 4210 9-Port Configuration Manual

Configure the NS Interval
After a device sends an NS message, if it does not receive a response within a specific period, the
device will send another NS message. You can configure the interval for sending NS messages.
Table 1-9 Configure the NS interval
To do...
Enter system view
Enter VLAN interface view
Specify the NS interval
Configure the neighbor reachable timeout time on an interface
After a neighbor passed the reachability detection, the device considers the neighbor to be reachable in
a specific period. However, the device will examine whether the neighbor is reachable again when there
is a need to send packets to the neighbor after the neighbor reachable timeout time elapsed.
Table 1-10 Configure the neighbor reachable timeout time on an interface
To do...
Enter system view
Enter VLAN interface view
Configure the neighbor
reachable timeout time

Configuring a Static IPv6 Route

You can configure static IPv6 routes for network interconnection in a small sized IPv6 network.

To do...
Enter system view
Configure a static IPv6
route

Configuring IPv6 TCP Properties

The IPv6 TCP properties you can configure include:
synwait timer: When a SYN packet is sent, the synwait timer is triggered. If no response packet is
received before the synwait timer expires, the IPv6 TCP connection establishment fails.
