Description
Indicates the system's DNS name. On IPv4 networks the system will send the host name
to the DHCP server in order to enable it to register the hostname with the local DNS
server and/or look up the domain where the endpoint is registered (if supported). This
function is not supported on IPv6, so you can leave this field unconfigured if you're using
an IPv6 network. However, configuring the field to contain the registered host name is
recommended.
Displays the domain name currently assigned to the system.
If the system does not automatically obtain a domain name, enter one here.
Specifies whether the system should automatically negotiate the LAN speed and duplex
mode per IEEE 802.3 autonegotiation procedures. If this setting is enabled, the LAN
Speed and Duplex Mode settings become read only.
Polycom recommends that you use autonegotiation to avoid network issues.
Specifies whether to use 10 Mbps, 100 Mbps, or 1000 Mbps for the LAN speed. Note
that the speed you choose must be supported by the switch.
Specifies the duplex mode to use. Note that the Duplex mode you choose must be
supported by the switch.
Enables the RealPresence Group system to ignore ICMP redirect messages.
You should enable this setting under most circumstances.
Specifies the minimum number of milliseconds between transmitted packets. Enter a
number between 0 and 60000. The default value of 1000 signifies that the system sends
1 packet per second. If you enter 0, the transmission rate limit is disabled.
This setting applies only to "error" ICMP packets. This setting has no effect on
"informational" ICMP packets, such as echo requests and replies.
Generates an ICMP Destination Unreachable message if a packet cannot be
delivered to its destination for reasons other than network congestion.
Sends an ICMP Echo Reply message in response to a broadcast or multicast Echo
Request, which is not specifically addressed to the RealPresence Group system.
Specifies the number of Duplicate Address Detection (DAD) messages to transmit before
acquiring an IPv6 address. The RealPresence Group system sends DAD messages to
determine whether the address it is requesting is already in use.
Select whether to transmit 0, 1, 2, or 3 DAD requests for an IPv6 address.
