Configuring the Test Set's LAN

Configuring the Test Set's LAN

Last updated: May 30, 2011

Description

LAN IP Address

   
CAUTION
Always verify that the test set is responding to a new LAN IP Address by pinging the test set. If the test set does not respond to the ping, cycle power. This will ensure that the test set will respond to the new LAN IP Address.
   

The LAN address is a character string with a maximum of 15 characters and a format of A.B.C. D where A is between 0 and 223 (excluding 127, which is assigned for use as the Internet host loopback address), and B, C, and D are between 0 and 255. No embedded spaces are allowed. The address may be manually set/viewed in the system configuration screen. The LAN address can be set/queried using the SYSTem subsystem.

The LAN address is a non-volatile parameter. The LAN address is not affected by any reset operation and can only be changed by direct access to the parameter itself.

   
NOTE
If the LAN address is set to a different network class, the subnet mask will change to the default net mask for the new network class.
   

For convenience the DATA port on the front panel may be configured as a LAN port. When an RJ45 jumper cable, (part number E5515-61160) is connected from the LAN PORT on the rear panel, to the ETHERNET TO FRONT PANEL port also on the rear panel, the user has LAN access from the front panel of the test set. Without the RJ45 jumper cable, the test set connection to a LAN is the rear-panel, LAN PORT connector.

The LAN address cannot be changed when the Operating Mode is set to Active Cell .

LAN Default Gateway

The LAN router, (default gateway), is a character string with a maximum of 15 characters and a format of A, B, C, D, where A is between 0 and 223 , and B, C, and D are between 0 and 255, no embedded spaces are allowed. If the default gateway is set to a format not allowed with the LAN address or the subnet mask that have been selected, the default gateway will be set to a null string, indicated by a blank field on the test set display. The address may be manually set/viewed in the system configuration screen. The LAN default gateway can be set/queried using the SYSTem subsystem.

The LAN default gateway is the address of a router that routes messages between networks and or subnets. If this value is not specified, LAN communications will be limited to the network and subnet specified by the LAN IP address and the subnet mask. Your network administrator will know if a default gateway is needed and if so, the address of the router. If the default gateway address is not needed by your network, it may be disabled by entering any of the following values: "0" (zero), "" (null string), "0.0.0.0"

The LAN default gateway is a non-volatile parameter. The LAN default gateway is not affected by any reset operation and can only be changed by direct access to the parameter itself.

LAN Subnet Mask

The LAN subnet mask address is a character string with a maximum of 15 characters and a format of A, B, C, D, where A , B, C, and D are between 0 and 255. No embedded spaces are allowed. The address may be manually set/viewed in the system configuration screen. The LAN subnet mask address can be set/queried using the SYSTem subsystem.

The subnet mask number combined with the IP address identifies which network and subnet your computer is on. Contact your system administrator for the correct subnet mask for your network.

The subnet mask determines the boundaries between the subnet ID and the host ID.

The LAN subnet mask is a non-volatile parameter. The LAN subnet mask is not affected by any reset operation and can only be changed by direct access to the parameter itself or by changes to the LAN IP Address.

   
NOTE
If the LAN address is set to a different network class, the subnet mask will change to the default net mask for the new network class.
   

The subnet mask number is obtained from your network administrator.

LAN 2 PORT

   
NOTE
You may not be able to set the LAN 2 PORT address due to hardware restriction. Contact your sales representative for more information.
   

The LAN 2 PORT allows you to use the Data Channel functionality with High Data Rate. To use the Data Channel functionality (to establish a Packet Data connection, for example), you must connect your data server to the LAN 2 PORT , rather than to the LAN 1 PORT as in the past.

Tip: The easiest way to identify whether the test set supports LAN 2 PORT is as follows: press the SYSTEM CONFIG hardkey, then press F1 ( Instrument Setup ) and go to the bottom of the Instrument IP Setup middle menu. Check if the LAN IP Address 2 (Data+) setting exists under the Restart on Fatal Error State setting, if not, then the test set does not support the LAN 2 PORT.

LAN 1 PORT is still used for all other LAN operations such as protocol logging, firmware downloads and screen captures.

The LAN 2 PORT connects directly to the test set's protocol processor.

You must configure the address of the LAN 2 PORT using the LAN IP Address 2 (Data+) setting (see LAN IP Address for general information about LAN IP addresses). LAN IP Address 2 (Data+) must not be identical to the LAN IP Address setting, and must be on the same subnet as the LAN IP Address setting. If LAN IP Address or Subnet Mask is changed such that LAN IP Address 2 (Data+) is identical to or is no longer on the same subnet as LAN IP Address , then LAN IP Address 2 (Data+) is set to 0.0.0.0 and a warning is posted.
