IPv4 Access List Creation on SG500X Series Stackable Switches

Objective

An Access List filters incoming and outgoing routes for an IP interface.  An Access List can do one of two actions, it can permit entry of packets from the IP addresses on the access list or it can deny entry of packets from the IP addresses on the access list.  Access Lists are used with the Routing Information Protocol (RIP).

This article explains how to create an Access List on the SG500X Series Stackable Switches.

Applicable Devices

• SG500X Series Stackable Switches

Software Version

• 1.3.0.62

Access List Settings

Step 1. Log in to the web configuration utility and choose IP Configuration > Access List > Access List Settings. The Access List Settings page opens:

Step 2. Click Add to add a new access list. The Add Access List window appears.

Step 3. Enter a name for the access list in the Name field.

Step 4. Click the radio button that corresponds with the desired source IPv4 address in the Source IPv4 Address field.

• Any — All IP addresses are included.

• User Defined — Enter an IP address in the User Defined field. This IP address is used as the source IP address.

Step 5. Click the radio button that corresponds with the desired source IPv4 mask in the Source IPv4 Mask field.

• Network mask — Enter the network mask in the Network mask field. This defines the subnet mask for the source IP address.

• Prefix length — Enter the prefix length (integer in the range of 0 to 32) in the Prefix length field. This defines the subnet mask by prefix length for the source IP address.

Note: Step 5 is only applicable if User Defined is clicked in the Source IPv4 Address field.

Step 6. Click the radio button that corresponds with the desired action in the Action field.

• Permit — Permits entry of packets from the IP address(es) chosen in the access list.

• Deny — Rejects entry of packets from the IP address(es) chosen in the access list.

Step 7. Click Apply.

Step 8. (Optional) Click the desired check box and click Delete to delete the access list.

Step 9. (Optional) Click Source IPv4 Address List to view all access lists with IPv4 addresses.
