Interface Types That Do Not Support CoS
For original Channelized OC12 PICs, limited CoS functionality is supported. For more information, contact Juniper Networks customer support.
 | Note: Transmission scheduling is not supported on 8-port, 12-port, and 48-port Fast Ethernet PICs. |
You can configure CoS on all interfaces, except the following:
- cau4—Channelized STM1 IQ interface (configured on the Channelized STM1 IQ PIC).
- coc1—Channelized OC1 IQ interface (configured on the Channelized OC12 IQ PIC).
- coc12—Channelized OC12 IQ interface (configured on the Channelized OC12 IQ PIC).
- cstm-1—Channelized STM1 IQ interface (configured on the Channelized STM1 IQ PIC).
- ct1—Channelized T1 IQ interface (configured on the Channelized DS3 IQ PIC or Channelized OC12 IQ PIC).
- ct3—Channelized T3 IQ interface (configured on the Channelized DS3 IQ PIC or Channelized OC12 IQ PIC).
- ce1—Channelized E1 IQ interface (configured on the Channelized E1 IQ PIC or Channelized STM1 IQ PIC).
- dsc—Discard interface.
- fxp—Management and internal Ethernet interfaces.
- lo—Loopback interface. This interface is internally generated.
- pe—Encapsulates packets destined for the rendezvous point routing device. This interface is present on the first-hop routing device.
- pd—De-encapsulates packets at the rendezvous point. This interface is present on the rendezvous point.
- vt—Virtual loopback tunnel interface.
Note: For channelized interfaces, you can configure CoS on channels, but not at the controller level. For a complex configuration example, see the Junos OS Feature Guides.
