Port Speed

Path: Administration > 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).

Ping Response

Path: Administration > Network > Ping Response

• Select the Enable check box for IPv4 Ping Response to allow the NMC to respond to network

pings. Clear the check box to disable an NMC response. This does not apply to IPv6.

Setting Description

Enable Enable or disable IPv6 with this check box.

Manual 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 NMC 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 NMC 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 NMC 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.
