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:
Enter the following information for one or both network ports in the following sections:
Eth1/Eth2 Settings |
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)
|
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. |
Eth1 and/or Eth2 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. |
Note: Configurations with the same IP subnet on multiple interfaces (Ethernet or PPP) are not currently supported.
Default |
IP address of the router for this network. If this has not been set manually, any gateway acquired by DHCP for Eth1 or Eth2 displays. All network traffic that matches the Eth1 IP address and subnet mask is sent out Eth1. All network traffic that matches the Eth2 IP address and subnet mask is sent out Eth 2. If you set a default gateway, any network traffic that does not match Eth1 or Eth2 is sent to the default gateway for routing. |
DHCP-Acquired (display only) |
Gateway acquired by DHCP for Eth1 or Eth2. |
GPRS-Acquired (display only) |
Displays the IP address of the router if it has been automatically assigned by General Packet Radio Service (GPRS). |
Precedence |
Indicates whether the gateway acquired by DHCP or the default gateway takes precedence. The default is DHCP Gateway. If the DHCP Gateway is selected and both Eth1 and Eth2 are configured for DHCP, the SLB gives precedence to the Eth1 gateway. |
Alternate |
An alternate IP address of the router for this network, to be used if an IP address usually accessible through the default gateway fails to return one or more pings. |
IP Address to Ping |
IP address to ping to determine whether to use the alternate gateway. |
Ethernet Port to Ping |
Ethernet port to use for the ping. |
Delay between Pings |
Number of seconds between pings |
Number of Failed Pings |
Number of pings that fail before the SLB uses the alternate gateway. |
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. |
Hostname |
The default host name is slcXXXX, 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. |
DNS Servers #1-3 |
Configure up to three name servers. At least one entry is required if you choose to configure DNS (Domain Name Server) servers. |
DHCP-Acquired DNS Servers (view only)#1-3
|
Displays the IP address of the primary name server if automatically assigned by DHCP |
GPRS-Acquired DNS Servers (view
only) |
Displays the IP address of the primary name server if automatically assigned by General Packet Radio Service (GPRS). |
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. |
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.
