Appendix C

Policies and Filters

The HP 9304M, HP 9308M, and HP 6308M-SX routing switches and the HP 6208M-SX switch provide a robust array of policies and filters. You can configure policies and filters to do the following:

•Change Quality-of-Service priorities for individual ports, VLANs, Layer 4 flows, static MAC entries, and AppleTalk sockets.

•Configure protocol-based VLANs, IP sub-net VLANs, and IPX network VLANs within standard 802.1d port­ based VLANs.

•Forward or drop IP packets based on source and destination IP addresses, Layer 4 information (such as TCP or UDP port), or both.

•Learn or drop IP/RIP routes on incoming traffic, based on network address or the IP/RIP neighbor’s IP address.

•Control learning and advertisement of IP/RIP routes, based on network address or the IP/RIP neighbor’s IP address.

•Forward or drop IPX packets based on source and destination network address and socket information.

•Control learning and advertisement of IPX RIP routes.

•Permit or deny access to IPX servers.

•Permit or deny AppleTalk zone and network information to reach other zones.

•Control learning and advertisement of routes learned from BGP4 neighbors. You can filter based on network address information, AS-path information, and community names.

•Redistribute routes among IP/RIP, OSPF, and BGP4.

•Filter on specific MAC addresses, on Layer 2 multicast packets, and on Layer 2 broadcast packets.

This appendix describes the various types of policies and filters. For each type of policy or filter, the CLI command syntax and the Web management links for configuring the policy or filter are provided. This appendix also refers you to specific configuration procedures.

NOTE: This appendix does not describe Access Control Lists (ACLs) or IPX SAP ACLs, which are additional methods for filtering packets. See “Using Access Control Lists (ACLs)” on page 3-1and “Configuring IPX SAP Access Control Lists (ACLs)” on page 14-9.
