QoS for the oversubscribed 16 x 10GE modules 18 The values of the remaining weights are calculated to be the following: w0 = 4.17%, w1 = 20.83%, w2 = 4.17%, w4 = 4.17%, w5 = 20.83%, w6 = 4.17%, and w7 = 20.83% Egress port shaping The 16x10GE module is designed to provide port fairness, but the cost is a smaller number of usable queues per input port (on egress). Traffic received on a network port will be assigned to one of 2 egress queues with a specific drop precedence value. Table 97 identifies the profile used for network control traffic which is identified using an independent flag.

You can monitor traffic on 16x10 ports. Supported ACLs The 16x10GE module supports standard, extended, named and numbered egress ACLs. Refer to Chapter 21, "Access Control List" for additional information. BigIron RX Series Configuration Guide 495 53-1001986-01
