Network Port Settings

Network parameters determine how the SLC interacts with the attached network. Use this page to set the following basic configuration settings for the network ports (Eth1 and Eth2).

Note: If you entered some of these settings using a Quick Setup procedure, you may update them here.

To complete the Network Settings  page:

  1. Enter the following information for one or both network ports in the following sections:

IP Addressing Options

IP Address (if specifying)

TCP Keepalive Settings

DNS Servers

DHCP-Aquired DNS Servers

GPRS-Acquired Servers

IP Addressing Options

Disabled

If selected, disables the network port. Defaults are Eth1 and Eth2 enabled.

Obtain from DHCP

Acquires IP address, subnet mask, hostname, and gateway from the DHCP server. (The DHCP server may not provide the gateway and hostname, depending on its setup.) By default, both Eth1 and Eth2 are enabled. If you select DHCP, skip to Hostname.

Obtain from BOOTP

Lets a network node request configuration information from a BOOTP "server" node.  If you select this option, skip to Hostname.

Specify

Lets you manually assign a static IP address, generally provided by the system administrator.

 

IP Address (if specifying)

Note: Configurations with the same IP subnet on multiple interfaces (Ethernet or PPP) are not currently supported.

IP Address

 

An IP address that will be unique and valid on your network. There is no default.

Note: Enter all IP addresses in dot-quad notation.  Do not use leading zeros in the fields for dot-quad numbers less than 100. For example, if your IP address is 172.19.201.28, do not enter 028 for the last segment.

Subnet Mask

The network segment on which the SLC resides. There is no default.

IPv6 Address

Address of the Ethernet port in IPv6 format.

Note: The SLC supports IPv6 connections for a limited set of services: the web, ssh, and Telnet.

IPv6 addresses are written as 8 sets of 4-digit hexadecimal numbers separated by colons. There are several rules for modifying the address. For example,

1234:0BCD:1D67:0000:0000:8375:BADD:0057 may be shortened to 1234:BCD:1D67::8375:BADD:57.

Eth1/Eth2 Mode

Select the direction (Full-Duplex or Half-Duplex) and speed (10 or 100Mbit) of data transmission. The default is Auto, which allows the Ethernet port to auto-negotiate the speed and duplex with the hardware endpoint to which it is connected.

Eth1/Eth2 Multicast

Displays the multicast address of the Ethernet port.

Hostname

The default host name is slbXXXX, where XXXX is the last 4 characters of the hardware address of Ethernet Port 1. There is a 64-character limit (contiguous characters, no spaces). The host name becomes the prompt in the command line interface.

Domain

If desired, specify a domain name (for example, support.lantronix.com). The domain name is used for host name resolution within the SLC. For example, if abcd is specified for the SMTP server, and mydomain.com is specified for the domain, if abcd cannot be resolved, the SLC attempts to resolve abcd.mydomain.com for the SMTP server.

Gateway

To enter gateway information, click the Settings link. The Gateway page displays.

Enable IP Forwarding

IP forwarding enables network traffic received on one interface (Eth1, Eth2, or an external/PC Card modem attached to the SLC with an active PPP connection) to be transferred out another interface (any of the above). The default behavior (if IP forwarding is disabled) is for network traffic to be received but not routed to another destination.

Enabling IP forwarding is required if you enable Network Address Translation (NAT) for any device port modem or PC Card/ISDN modem. IP forwarding allows a user accessing the SLC over a modem to access the network connected to Eth1 or Eth2.

TCP Keepalive Settings

Start Probes

Number of seconds the SLC waits after the last transmission before sending the first probe to see whether a TCP session is still alive. The default is 600 seconds (10 minutes).

Number of Probes

Number of probes the SLC sends before closing a session. The default is 5.

Interval

The number of seconds the SLC waits between sending probes. The default is 60 seconds.

DNS Servers

#1

IP address of the primary name server. This entry is required if you choose to configure DNS (Domain Name Server) servers.

#2 (optional)

IP address of the secondary DNS name server.

#3 (optional)

IP address of the tertiary DNS name server.

DHCP-Acquired DNS Servers (view only)

#1

 

Displays the IP address of the primary name server if automatically assigned by DHCP

#2

 

Displays the IP address of the second name server if automatically assigned by DHCP

#3

 

Displays the IP address of the third name server if automatically assigned by DHCP

GPRS-Acquired DNS Servers (view only)

#1

Displays the IP address of the primary name server if automatically assigned by General Packet Radio Service (GPRS).

#2

Displays the IP address of the second DNS server if assigned by GPRS.

#3

Displays the IP address of the third DNS server if assigned by GPRS.

 

  1. To save your entries, click the Apply button.  Apply makes changes effective immediately and saves them so they will be there when the SLC is rebooted.
