What is FPC in Juniper router?
FPC – Flexible PIC Concentrator – PICS go into FPC’s on larger routers – – example 4 PIC’s to an FPC – used in larger routers.
What is router FPC?
The FPC is a component of the Packet Forwarding Engine. FPCs house the various PICs used in the router. The FPCs installed in the router depend on the platform and the PICs needed. Table 1 provides some FPC characteristics for each router type.
What does Juniper FPC stand for?
Flexible PIC Concentrator
M320 Flexible PIC Concentrator (FPC) Description – TechLibrary – Juniper Networks.
What is PIC in router?
A PIC is an interface card through which network cables carry data transmissions to and from the network plug. A PIC installs into a Flexible PIC Concentrator (FPC). Before transmitting outgoing data packets, the PICs encapsulate packets received from the FPCs.
What are three functions of the re Juniper?
The RE’s primary functions are to manage the PFE, control the device’s software (Junos operating system), manage the command-line interface (CLI), provide troubleshooting tools, and maintain the route tables (both the route table and the route forwarding table).
What are two functions of the PFE Juniper?
On Juniper Networks routers, the PFE is designed to perform Layer 2 and Layer 3 switching, route lookups, and rapid forwarding of packets. Using ASICs, the strategy of the PFE is to divide and conquer the business of forwarding.
What is PIC Juniper?
Flexible PIC Concentrators (FPCs) and Physical Interface Cards (PICs) function similarly to MICs and MPCs. PICs provide physical interfaces for the router and install into FPCs which provide packet forwarding services. Each FPC supports up to two Physical Interface Cards (PICs).
What is the difference between router and modem?
Your modem is a box that connects your home network to the wider Internet. A router is a box that lets all of your wired and wireless devices use that Internet connection at once and also allows them to talk to one another without having to do so over the Internet.
What are the two functions of PFE?
The PFE is the central processing component of the forwarding plane. The PFE uses Layer 2 and Layer 3 forwarding tables to forward traffic toward its destination. The PFE implements various services such as policing, stateless firewall filtering, and class of service.
What is a function of the PFE Juniper?
The Packet Forwarding Engine (PFE) is the central processing element of the forwarding plane, systematically moving the packets in and out of the device. In the Junos OS, the PFE has a locally stored forwarding table.
What is a juniper line card?
The MX10K-LC2101 line card is a fixed configuration MPC and it does not contain separate slots for Modular Interface Cards (MICs). The line card provides a maximum bandwidth of 2.4Tbps and has six Packet Forwarding Engines, each providing a maximum bandwidth of up to 400 Gbps.
What happens when you install a FPC into a router?
When you install an FPC into a functioning router, the Routing Engine downloads the FPC software, the FPC runs its diagnostics, and the PICs, housed on the FPC, are enabled. Forwarding continues uninterrupted during this process.
Where does a Flexible PIC concentrator ( FPC ) install?
Up to eight Flexible PIC Concentrators (FPCs) install vertically in the front of the router (see Figure 1 ). The FPC slots are numbered left to right from FPC0 to FPC7. Depending on the FPC type, an FPC has either two or four slots into which a PIC can be installed (see M320 FPCs Supported for more information).
Can a PIC be installed into any FPC slot?
Depending on the FPC type, an FPC has either two or four slots into which a PIC can be installed (see M320 FPCs Supported for more information). An FPC can be installed into any FPC slot on the router, regardless of which PICs it contains.
How many FPC slots are there in M320?
The FPC slots are numbered left to right from FPC0 to FPC7. Depending on the FPC type, an FPC has either two or four slots into which a PIC can be installed (see M320 FPCs Supported for more information). An FPC can be installed into any FPC slot on the router, regardless of which PICs it contains.
