# Filtering IP Source Guard addresses using EDM

Use the following procedure to filter IP Source Guard addresses to display IP Source Guard information for specific IP addresses.

Important

Hardware resources can run out if IP Source Guard is enabled on trunk ports with a large number of VLANs, which have DHCP snooping enabled. If this happens, traffic sending can be interrupted for some clients. Avaya recommends that IP Source Guard not be enabled on trunk ports.

Important

The IP addresses are obtained from DHCP snooping binding table entries defined automatically in the port. A maximum 10 IP addresses from the binding table are allowed and the rest are dropped.

## Prerequisites

Before you can configure IP Source Guard, you must ensure the following:

- Dynamic Host Control Protocol (DHCP) snooping is globally enabled.

  For more information about, see Configuring DHCP snooping globally using EDM.

- The port is a member of a Virtual LAN (VLAN) configured with DHCP snooping and dynamic Address Resolution Protocol (ARP) Inspection.

- The port is an untrusted DHCP snooping and dynamic ARP Inspection port.

- A minimum of 10 rules are available on the port.

- The bsSourceGuardConfigMode MIB object exists.

  This MIB object is used to control the IP Source Guard mode on an interface.

- The following applications are not enabled:

  - IP Fix

  - Extensible Authentication Protocol over LAN (EAPoL)

## Procedure steps

1. From the navigation tree, double-click Security.

2. In the Security tree, double-click IP Source Guard (IPSG).

3. In the work area, click the IP Source Guard-addresses tab.

4. In the table, select a record.

5. In the toolbar, click Filter.

   The IP Source Guard-addresses - Filter tab appears.

6. Configure the parameters as required.

7. Click Filter.

## Variable definitions

Use the data in the following table to filter IP Source Guard addresses.

Ignore Case | Ignores the letter case while searching.
Column | Searches the columns based on the content of column search specified. Possible values are Contains Does not contain Equals to Does not equal to
All records | Displays all entries in the table.
Port | Searches for the specified port.
Address | Searches for the specified IP address.
