Chapter 12 Avaya P330 Layer 3 Features

Enforcement

P333R-LB can enforce policy rules on traffic addressed to its interfaces. This feature enables you to block any configuration (e.g., SNMP, TELNET, and HTTP) of the router/load balancer.

Default List Behavior

P333R-LB has a default list which is always active. The default list has one implicit rule permitting all traffic to be forwarded. The DSCP table of the default list is activated together with the default list, and includes the default DSCP-CoS mappings.

Policy and Load Balancing

P333R-LB can enforce policy rules relating to Virtual IP addresses and to the original Client IP. P333R-LB can not enforce policy rules relating to PIP addresses.

When a packet destined to a Virtual IP address is processed by P333R-LB, it checks the packet against the active policy list before any NAT manipulation is performed on the packet. Upon returning from the real servers, the packet is checked against the active policy list after NAT was performed.

P333R-LB Policy Properties

P333R-LB supports QoS and Access Control rules pertaining to source IP addresses, destination IP addresses, any IP protocol, any specific TCP/UDP port, and the ACK bit of the TCP header. It also supports QoS rules on up to 3 port-ranges of TCP/ UDP.
