CoS on 10-Gigabit Ethernet LAN/WAN PIC with SFP+ Overview
The 10-Gigabit Ethernet LAN/WAN PIC with SFP+ supports intelligent handling of oversubscribed traffic in applications, such as data centers and dense-core uplinks. The 10-Gigabit Ethernet LAN/WAN PIC with SFP+ supports line-rate operation for five 10-Gigabit Ethernet ports from each port group or a total WAN bandwidth of 100 Gbps with Packet Forwarding Engine bandwidth of 50 Gbps.
This PIC has a front panel label with the designation “ETHERNET 10GBASE-SFP+ LAN-WAN” and can also be identified by its model number, PD-5-10XGE-SFPP. It is referred to hereafter as the 10-Gigabit Ethernet LAN/WAN PIC.
The class-of-service (CoS) configuration for the 10-Gigabit Ethernet LAN/WAN PICs are supported on standalone T640 and T1600 core routers, as well as T640 and T1600 routers in a routing matrix. The 10-Gigabit Ethernet LAN/WAN PICs support behavior aggregate (BA) and fixed classification, weighted round-robin scheduling with two queue priorities (low and strict-high), committed and peak information rate shaping on a per-queue basis, and excess information rate configuration for allocation of excess bandwidth.
To configure these features, include the corresponding class-of-service
(CoS) statements at the [edit class-of-service] hierarchy
level. The CoS statements supported on the 10-Gigabit Ethernet LAN/WAN
PICs are shown in Table 1.
