UPS Network Management Card 2 User’s Guide62
download the .ini file. After the download, the Management Card uses the .ini file as a boot file to
reconfigure its settings.
Path: Administration > Network > TCP/IP > IPv6 settings
Ping Response
Path: Administration > Network > Ping Response
Select the Enable check box for IPv4 Ping Response to allow the Network Management Card to
respond to network pings. Clear the check box to disable a Management Card response. This does not
apply to IPv6.
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.
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 Management Card checks whether the M or the O flag is set.
The Management Card 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 Management
Card 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 Management Card
performs full address configuration upon receipt of the M flag
• Only O is set: In this situation, the Management Card 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.
