Network Management Card User’s Guide57

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).

DNS

Path: Administration > Network > DNS > options

Use the options under DNS on the left navigation menu to configure and test the Domain Name System

(DNS):

• Select servers to specify the IP addresses of the primary and optional secondary DNS server. For

the Management Card to send e-mail, at least the IP

address of the primary DNS server must be

defined.

– The Management Card waits up to 15 seconds for a response from the primary DNS server or

the secondary DNS server (if a secondary DNS server is specified). If the Management Card

does not receive a response within that time, e-mail cannot be sent. Therefore, use DNS

servers on the same segment as the Management Card or on a nearby segment (but not across

a wide-area network [WAN]).

– After you define the IP addresses of the DNS servers, verify that DNS is working correctly by

entering the DNS name of a computer on your network to look up the IP address for that

computer.

• Select naming to define the host name and domain name of the Management Card:

– Host Name: After you configure a host name here and a domain name in the Domain Name

field, users can enter a host name in any field in the Management Card interface (except e-mail

addresses) that accepts a domain name.

– Domain Name (IPv4): You need to configure the domain name here only. In all other fields in

the Management Card interface (except e-mail addresses) that accept domain names, the

Management Card adds this domain name when only a host name is entered.

• To override all instances of the expansion of a specified host name by the addition of the

domain name, set the domain name field to its default, somedomain.com, or to

0.0.0.0.

• To override the expansion of a specific host name entry (for example, when defining a trap

receiver), include a trailing period. The Management Card recognizes a host name with a

trailing period (such as mySnmpServer.) as if it were a fully qualified domain name

and does not append the domain name.

• Domain Name (IPv6): Specify the IPv6 domain name here.
