interfaceВ feesВ orВ linearВ cardsВ Juniper NetworksВ (line card, interface module) В allow you to expand your router or switch (modular platform, chassis) Required functional, including the necessary access ports at speedsВ 1GbE,В 10GbE,В 40GbEorВ 100GbE, control boards (switch control board) etc..
Interface boards JuniperВ represented by various modules that are compatible with a particular series (for example. interface module MS-MIC-16G compatible with the entire rangeВ Juniper MX, and the module MPC-3D-16XGE-SFPP series compatibleВ MX240,В MX480В andMX960).
interface board MICВ (Modular Interface Cards) is a small-sized module that provides physical connection to various types of network devices. MIC the board can support various physical interfaces in one module.В module Juniper MICsВ also support hot swapping and plugging. For example, in routers MX series, interface moduleВ MICВ installed in the moduleВ MPCВ (Modular Port Concentrator), and in series fromВ MX5В beforeВ MX104В moduleВ MPCВ already built in chassis.
interface module Juniper MPCВ (Modular Port Concentrator) provides transfer services Lkand packages. moduleВ MPCВ encapsulates packets and passes them through the module's outgoing interfacesВ MIC. everyoneВ MPC moduleВ equipped with up to four chipsetsВ Junos Trio, which performs the functions of management. For example, a router Juniper MX960 supports installation of up to 12 modules MPCs, and the platform MX480 before 3 MPCs. For proper operationВ module Juniper MPCВ You need to use high-performance cooling modules. Online JuniperВ http://www.juniper.netВ there is a calculator for calculating the recommended power and cooling power, for a specific series and used MPC modules. В В
Interface modules DPCВ (Dense Port Concentrators) Provides several physical interfaces and pass systems Lkand packages on a single board that fits into a slot in a router or modular chassis.В module DPCВ accepts incoming packets and sends outgoing packets to the network.
module Juniper PICВ (Physical Interface Card) installed inВ FPCВ (Flexible PIC Concentrators), similar to how they workВ MICВ andMPC modules.В PICsВ modules provide physical interfaces, andВ FPCsВ boards provide transfers Lkfor packets on the network. everyoneВ FPCthe module is equipped with a microchipВ ASIC, which performs the functions of management, andВ FPCВ supports installation of 2 modulesВ PIC.

Syntax: ge-fpc/pic/portВ where:
В·В В В В В В В В fpc: Slot in the router where the MPC is installed
В·В В В В В В В В pic: 0 (left grouping of 10 ports) or 1 (right grouping of 10 ports) when installed in MIC slot 0; 2 (left grouping of 10 ports) or 3 (right grouping of 10 ports) when installed in MIC slot 1
В·В В В В В В В В port: 0 through 9
For example, ge-1/3/0 is the interface for port 0 in the right grouping of ports on the MIC installed in MIC slot 1 on an MPC installed in slot 1.
