Cisco Systems DL-2159-05 manual Enabling a Protocol Filter

Chapter 5 Configuring Filters and QoS

Filter Setup

Step 9 Select forward or block from the Disposition drop-down menu to forward or block the protocol traffic, or leave this setting at default to use the default disposition that you selected for the filter set in Step 6.

Step 10 Select a priority for the protocol from the Priority drop-down menu. The menu includes the following options:

•background—Use this setting for bulk transfers and other activities that are allowed on the network but should not impact network use by other users and applications.

•default—This setting is the same as best effort, which applies to normal LAN traffic.

•excellentEffort—Use this setting for a network’s most important users.

•controlledLoad—Use this setting for important business applications that are subject to some form of admission control.

•interactiveVideo—Use this setting for traffic with less than 100 ms delay.

•interactiveVoice—Use this setting for traffic with less than 10 ms delay.

•networkControl—Use this setting for traffic that must get through to maintain and support the network infrastructure.

Step 11 Enter milliseconds in the Time-to-Live entry fields. If you leave these settings at 0, the protocol adopts the default time-to-live values you entered in Step 7.

Note The time-to-live values you enter should be compatible with the priority you select for the protocol. For example, if you select interactiveVoice as the priority and enter high time-to-live values, voice packets will stay in the access point buffer longer than necessary, causing delivery of stale, useless packets.

Step 12 Select Alert? yes to send an alert to the event log when a user transmits or receives the protocol through the access point.

Step 13 Click OK. The Filter Set page appears with the protocol listed at the bottom of the page.

To edit the protocol entry, type the protocol name in the Special Cases entry field or click the select button beside the entry and click Edit. To delete the protocol, type the protocol name in the Special Cases entry field or click the select button beside the entry and click Remove.

Step 14 To add another protocol to the filter set, repeat Step 8 through Step 13. When you have included all the protocols you need in the filter set, click OK. The EtherType Filters, IP Protocol Filters, or IP Port Filters page appears, and the filter sets you defined appear in the filter set list at the bottom of the page.

Note After defining the protocol filter set, follow the steps in the Enabling a Protocol Filter section to activate the filter.
