Cisco SCE 8000 CLI Command Reference

Chapter 2 CLI Command Reference

traffic-side (SCE 8000 10G platform only)

Changes the traffic direction on Link 1 of the Cisco SCE 8000 10G platform.

Note This command is supported only on10 Gigabit Ethernet line interfaces 3/2/0 and 3/3/0. It is not supported

on interfaces 3/0/0 and 3/1/0.

Use the default form of the command to reset the interface to the default traffic direction.

Command History This table includes the following release-specific history entries:

Usage Guidelines The hardware design of the Cisco SCE 8000 10G platform is such that the traffic coming in and out of

SPAs 0 and 2 is limited to a total of 16Gbps in each direction, as is the traffic coming in and out of SPAs

1 and 3. Since by default, in 10GBE installations, SPAs 0 and 2 are subscriber-side ports, and SPAs 1

and 3 are network-side ports, this effectively limits total traffic in each direction (upstream and

downstream) to 16Gbps. Therefore, a site that has a total of more than 16Gbps of traffic in one direction

(upstream or downstream), will exceed this limit and suffer packet loss.

You can use this command to swap the roles of the ports on link 1, which will switch part of the

high-volume traffic to the opposite pair of SPAs and prevent either pair of SPAs from exceeding the

16Gbps limit.

Limitations

• This command is supported only Link 1 (3/2/0 and 3/3/0). It is not supported on Link 0.

Only one interface on the link is explicitly configured. The corresponding interface is automatically

set to the opposite traffic side.

• The connection mode must be either inline or receive-only. This command is not supported for

cascade modes.

subscriber Configure the interface to process subscriber traffic.

network Configure the interface to process network traffic.
