 Subnet Mask This field displays the subnet mask currently assigned to the system. If the
system does not automatically obtain a subnet mask, enter one here.
● DNS Servers
 DNS Servers Displays the DNS servers currently assigned to the system. If the system does
not automatically obtain a DNS server address, you can enter up to four DNS servers here.
 You can specify IPv4 DNS server addresses only when the IPv4 address is entered
manually. When the IPv4 address is obtained automatically, the DNS Server addresses are
also obtained automatically.
● LAN Options
 Host Name Indicates the system’s Domain Name System (DNS) name.
 This LAN option applies only to IPv4 environments and is available only on the web
interface.
 Domain Name Displays the domain name currently assigned to the system. If the system
does not automatically obtain a domain name, enter one here.
 This LAN option applies only to IPv4 environments and is available only on the web
interface.
 Autonegotiation Specify whether the network switch should automatically negotiate the LAN
speed and duplex mode. If this setting is enabled, the LAN Speed and Duplex Mode settings
become read only.
 LAN Speed Specify 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.
Note: LAN speed settings for the Polycom Group Series and switch must be the
same.
Polycom does not support Auto for the Polycom Group Series only or the switch only; the
settings for both must be the same.
 Duplex Mode Specify the duplex mode to use. Note that the Duplex mode you choose must
be supported by the switch. Choose one of the following options:
 Half Duplex Half Duplex provides communication in both directions, but only one direction
at a time (not simultaneously).
 Full Duplex Full Duplex allows communication in both directions simultaneously.
 Ignore Redirect Messages Enables the HDX system to ignore redirect messages from
network routers. A redirect message tells the endpoint to use a different router than the one it is
using.
 This LAN option applies only to IPv4 environments and is available only on the web
interface.
 ICMP Transmission Rate Limit (millisec) 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.
