APPENDIX

Using Optical Splitters with 10GBE Links

• Supported Configurations, page A-1

• Unsupported Configuration, page A-2

When designing a deployment with the SCE8000, it is important to keep in mind certain characteristics

of the 10GBE link that affect the configuration of optical splitters and SPAN ports.

• Ten Gigabit Ethernet does not support autonegotiation (unlike regular GBE). The fixed 10GBE

configuration is as follows:

–

duplex = full

–

speed = 10 GBE

• The 10GBE port is UP once it detects light (and correct sync pattern) in the RX input.

• A Switch or Router port will not transmit data unless it is UP (that is, it detects a good signal on the

RX input).

Supported Configurations

Due to the 10GBE characterstics described above, the following configurations are supported in the 10

GBE environment.
