Cisco 76-ES+XT-8TG Line Card Overview

Port Mapping: The ES+ HD has eight 10GE ports. The first port of each NP is numbered from 1 to 4 (NP 0 to NP 3), and each NP’s second 10GE port is numbered from 5 to 8.

Oversubscription: Theoretically each NP supports 15Gb on the egress side. For instance, 10Gb traffic is sent from the line card to NP, which has 5Gb of multicast and 5Gb of unicast traffic. Using loopback interface, the NP replicates the multicast packets and sends 5Gb traffic on each NP port. This traffic is divided into 2.5Gb on each port. So, effectively each NP port or interface receives 7.5Gb traffic. Since there are two 10Gb ports on each NP, the total rate achieved is 15Gb.

On the ingress path, more than 10Gb is supported for higher packet size. For instance, when the NP receives the packets at the rate of 10Gb, and each packet size is 64 bytes, it will be 96 bytes (64 +32 byte DBUS header) when it moves from NP to line card. So, it consumes entire bandwidth and restrict the ingress traffic to 10Gb. If the packet size is greater than 64 bytes, it will give more than 10Gb throughput.
