Release Information

Statement introduced in Junos OS Release 11.2.

Support for MPC7E (Multi-Rate) introduced in Junos OS Release 15.1F4.

Support for MX10003 MPC introduced in Junos OS Release 17.3R1.

Support for MX204 routers introduced in Junos OS Release 17.4R1.

Description

Configure the port speed on MX Series routers. This statement is supported only on MPC7E (Multi-Rate) MPC, SONET/SDH (Multi-Rate) MICs with SFP, Channelized SONET/SDH OC3/STM1 (Multi-Rate) MICs with SFP, ATM MICs, and MX204 routers.

Default

oc3-stm1

Options

oc3-stm1—Supported ports operate at OC3 or STM1 speed.

oc12-stm4—Supported ports operate at OC12 or STM4 speed.

oc48-stm16—Supported ports operate at OC48 or STM16 speed.

100G—Supported ports operate at 100-Gbps speed.

10G—Supported ports operate at 10-Gbps speed.

40G—Supported ports operate at 40-Gbps speed.

Note

You can configure the oc12-stm4, oc3-stm1, and oc48-stm16 port speed options for SONET/SDH OC3/STM1 (Multi-Rate) MICs. However, for Channelized SONET/SDH OC3/STM1 (Multi-Rate) MICs with SFP and ATM MICs, you can configure only the oc12-stm4 and oc3-stm1 port speed options.

(MX Series with MPCs and ATM MICs with SFP) To configure up to OC12 CBR bandwidth speed per virtual circuit (VC) on an ATM MIC with SFP (MIC-3D-8OC3-2OC12-ATM), specify oc12-stm4 as the speed for the specified port. You can configure the oc12-stm4 port speed option only for ports 0 and 4 on an ATM MIC. If you configure the oc12-stm4 port speed option for port 0, then ports 1, 2, and 3 are disabled. Similarly, if you configure the oc12-stm4 port speed for port 4, then ports 5, 6, and 7 are disabled.

(MX Series with MPC7E-MRATE) To configure 100-Gbps, 10-Gbps, or 40-Gbps speed per port on an MPC7E (Multi-Rate) MPC, specify 100G, 10G, or 40G, respectively, as the speed for the specified port. You can configure 10G and 40G port speed options on all the six ports of PIC 0 and PIC 1 of an MPC7E-MRATE MPC. However, you can configure the 100G port speed option only for ports 2 and 5 of PIC 0 and PIC 1 of an MPC7E-MRATE MPC.

(MX10003 routers with MX10003 MPC) To configure 100 Gbps, 10 Gbps, and 40 Gbps speed on all supported ports, specify 100G, 10G, or 40G, respectively, as the speed for the specified PIC. All the six ports of the fixed port PIC support 10-Gbps and 40-Gbps speeds. All the 12 ports of the Multi-rate MIC support 100-Gbps, 10-Gbps and 40-Gbps speeds. For more information see MX10003 MPC on MX10003 Router Overview and Supported Active Physical Ports for Configuring Rate Selectability to Prevent Oversubscription on MX10003 MPC.

(MX204 Routers) The MX204 has four rate-selectable ports (referred to a PIC 0 ports) that can be configured as 100-Gigabit Ethernet ports or 40-Gigabit Ethernet port, or each port can be configured as four 10-Gigabit Ethernet ports (by using a breakout cable). The MX204 also has eight 10-Gigabit Ethernet ports (referred to as PIC 1 ports).
