•metricout <increment value> This modifier tells the device to increment the metric on outgoing routes which match the filter rule. By increasing or decreasing the metric, a particular route can be made more or less attractive. The value to increment by can be from 1 to 15.
IPX Route Filter Rule Notification
Filter rule matches can optionally cause a log message to be sent. By default, no logging of matches is performed. See the section on the Logging Config- uration Dialog Box of this manual for more information.
•log The log keyword causes the device to send information about the packet to syslog when the condition of the rule is met.
IPX Route Filter Rule Examples
The following example specifies a rule to allow routes to be input from any IPX network except network number 7.
permit network != 7
The rule below specifies that routing information should only be accepted from the Ethernet 0 interface.
permit network = ALL from ethernet 0
IPX SAP Filter Rules
To access a dialog box for IPX SAP filters, open the Main IPX Filtering Dialog Box (under Global/Filtering/IPX Filtering) and then select the SAP Filters button.
SAP filtering rules are applied globally in the device and are not associated with any interface. However, they can be restricted to an interface using the “from” or “to” modifiers in the rule.
A device does not reorder rule sets as they have been specified before they are applied. They are applied in the order they were written. When multiple filter sets are selected with CompatiView, the filter sets will be concatenated in the device from first to last (top to bottom on screen).
Any server not explicitly allowed by the rules will not be included in the SAP table on input or in the SAP update on output. To allow all other servers not filtered, the last rule must be:
permit
