400g

Supported ports operate at 400-Gbps speed.

40g

Supported ports operate at 40-Gbps speed.

50g

Supported ports operate at 50-Gbps speed.

oc12-stm4

Supported ports operate at OC12 or STM4 speed.

oc3-stm1

Supported ports operate at OC3 or STM1 speed.

oc48-stm16

Supported ports operate at OC48 or STM16 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 seeMX10003 MPC (Multi-Rate) and Supported Active Physical Ports for Configuring Port Speed 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). For more information, see MX204 Router Overview and Supported Active Physical Rate-Selectable Ports to Prevent Oversubscription on MX204 Router

(PTX1000 routers) The PTX1000 routers has 72 network ports that support the QSFP+ transceivers and can be configured as channelized 4x10-Gigabit Ethernet interfaces by default (for a maximum of 288 10-Gigabit Ethernet ports). When you configure the speed of a port, you must reset the FPC for the configuration to take effect. If you do not reset the FPC after modifying the port speed configuration, the router displays the following error message:

pic_need_skip_port_speed_change: pic-0/0: Port speed changed while previous port speed transition is pending. This PIC needs to be restarted. Please take this PIC or FPC offline and online via CLI.

(PTX10001-36MR routers) See Port Speed on PTX10001-36MR Router Overview to learn about multiple port speeds supported on PTX10001-36MR router, guidelines, and how to configure the port speed.

(PTX10003-80C and PTX10003-160C) To configure 100-Gbps, 10-Gbps, or 40-Gbps speed per port on the PTX10003-80C and PTX10003-160C line cards, specify 100g, 10g, or 40g, respectively, as the speed for the specified port. Use the number-of-sub-ports statement to configure the number of channels for a particular port if the optics are used in a channelized mode. Use the number-of-sub-ports statement with the speed statement to configure a supported for the different channels based on the optics used. See PTX10003 Router Port Speed Overview for more details.

(ACX5448-D) To configure 100-Gbps, 10-Gbps, or 40-Gbps speed per port on the ACX5448-D router, specify 100g, 10g, or 40g, respectively, as the speed for the specified port.
