Enterasys Networks 2H252, 2E253, 2H253, 2H258 manual Entering Ranges of Addresses

Access Control List Screen

The designated devices associated with the IP addresses in the ACL will now be the only ones to have remote access to Local Management. Access to Local Management using the COM port is not affected.

Entering Ranges of Addresses

1.Use the arrow keys to highlight one of the place holders (0.0.0.0) under IP Addresses.

2.Enter the IP address of a device that you want to have access to Local Management using the following format: nnn.nnn.nnn.nnn (where n is an alphanumeric character).

3.Use the arrow keys to highlight the Mask field and type in the appropriate Mask value to establish a range of addresses based on the IP address entered. For example, if an IP address of 123.123.20.25 and a mask value of 255.0.0.0 was entered, all IP addresses starting with 123 would have access to Local Management.

4.Repeat steps 1 through 3 if more than one range of addresses is being entered. Up to 16 ranges of IP addresses, including any single IP Addresses entered. If an invalid format is used to enter an IP address, one of the following messages may display in the Event Message Line:

•“INVALID IP FORMAT” if more than 3 periods are entered.

•“INVALID IP” if numbers greater than 255 are entered.

•“DUPLICATE IP” if a duplicate IP address is entered.

•“INTERNAL IP” if the IP of the device is entered. Then the field returns to 0.0.0.0.

5.Use the arrow keys to highlight the Access Control Lists field.

6.Press the SPACE bar to toggle the field to ENABLED.

7.Press ENTER.

8.Use the arrow keys to highlight the SAVE command and press ENTER. The message “SAVED OK” displays on the screen.

NOTE: Exiting without saving causes a “NOT SAVED?” message to display above the SAVE command. Edits are lost if they are not saved before exiting.
