Configure network port speed
Path: Configuration > Network > Port Speed
The Port Speed setting defines the communication speed of the TCP/IP port.
• For Auto-negotiation (the default), Ethernet devices negotiate to transmit at the highest possible
speed, but if the supported speeds of two devices are unmatched, the slower speed is used.
• Alternatively, you can choose 10 Mbps or 100 Mbps, each with the option of half-duplex
(communication in only one direction at a time) or full-duplex (communication in both directions
on the same channel simultaneously).
Setting Description
IPv6 Enable or disable IPv6 with this check box.
Manual
Configuration
Configure IPv6 manually by entering the IP address and the default gateway.
Auto
Configuration
When the Auto Configuration check box is selected, the system obtains addressing prefixes
from the router (if available). It uses those prefixes to automatically configure IPv6 addresses.
DHCPv6
Mode
Router Controlled: Selecting this option means that DHCPv6 is controlled by the Managed
(M) and Other (O) flags received in IPv6 router advertisements. When a router advertisement
is received, the ATS checks whether the M or the O flag is set. The NMC interprets the state of
the M (Managed Address Configuration Flag) and O (Other Stateful Configuration Flag) "bits"
for the following cases:
• Neither is set: Indicates the local network has no DHCPv6 infrastructure. The ATS uses
router advertisements and manual configuration to get addresses that are not link-local and
other settings.
• M, or M and O are set: In this situation, full DHCPv6 address configuration occurs. DHCPv6 is
used to obtain addresses AND other configuration settings. This is known as
DHCPv6
stateful
. Once the M flag has been received, the DHCPv6 address configuration stays in
effect until the interface in question has been closed. This is true even if subsequent router
advertisement packets are received in which the M flag is not set.
If an O flag is received first, then an M flag is received subsequently, the ATS performs full
address configuration upon receipt of the M flag
• Only O is set: In this situation, the NMC sends a DHCPv6 Info-Request packet. DHCPv6 will
be used to configure “other” settings (such as location of DNS servers), but NOT to provide
addresses. This is known as DHCPv6 stateless.
Address and Other Information: With this radio box selected, DHCPv6 is used to obtain
addresses AND other configuration settings. This is known as DHCPv6
stateful.
Non-Address Information Only: With this radio box selected, DHCPv6 will be used to
configure "other" settings (such as location of DNS servers), but NOT to provide addresses.
This is known as DHCPv6
stateless.
Never: Select this to disable DHCPv6.
