Network

The moment you get into the hands of Mikrotik RouterOS is the default setting. Every time you boot is initialized and any supported hardware is immediately ready for use. In the default setting, all devices are prohibited. Primitive This must be done via the command line. To that can be accessed via the serial interface or directly via the console (monitor + keyboard). The command line enables complete administration RouterOS. The controls are very intuitive (not to deny his resemblance to the console of Cisco) and are equipped with a rich Help, which can be recalled at any time by typing a question mark “?”. Nevertheless, we assume that Most novice users will be more graphical interface WinBox. To use it, You must set the IP address and enable network interface (interface), through which the RouterOS connecting. For these purposes, RouterOS has a simple wizard that run after logged out of the system.

When you see an fcs error it is almost always the cabling on the radio at the other end of the link from where you see the FCS errors.

You can change cables over and over again on the side where the FCS occur and have minimal results.

It can be a bad cable from media converter to Mikrotik, bad media converter, the problem with fiber optic cable between 2 media converters, port on neighbor device and of course port on Mikrotik.

In this article, we’ll look at the following topics:

• IP Precedence bits
• Random Early Detection (RED)
• Committed Access Rate (CAR)
• Some Cisco QoS Links

The IP Precedence bits allow us to specify what traffic gets what Class of Service. RED lets us selectively drop TCP packets to throttle the sender, providing better goodput. And CAR is input-side traffic admission control, allowing us to police inbound traffic.

IP Precedence Bits

Part of the new IP QoS tool kit in routers and switches is the IP Precedence bits. Devices at the edge of the network may classify traffic as deserving a certain Class of Service using these bits. Core devices can then use the bits to provide differing types of service to different flavors of traffic.

Mikrotik Fetch Tool is one of the tools on the console/terminal Mikrotik RouterOS that works to copy (copy) files through FTP, HTTP, and https protocol. This Fetch tool can copy files from other devices to Mikrotik Router (download) or copy files from Mikrotik Router to other devices (upload). So its use is similar like wget on linux, with the different command.

Until RouterOS version 6.38.1, Mikrotik fetch tool still no fetch menu in its Winbox GUI. So to use this fetch tool we still have to type the command on Mikrotik terminal. It does not matter because the use of his command will be discussed one by one in this Mikrotik Tutorial until easy to understand.

What Is QoS?

QoS stands for Quality of Service. The term is being used by Cisco to refer to IP-based features that allow specification and delivery of services much like the Quality of Service features in ATM.

When you get right down to it, there isn’t all that much a router can do to control traffic, since it is not the originator of most of the traffic. The router can drop traffic — although we’d prefer it didn’t do so. It can put some queued frames out an interface before others. It can be selective about accepting traffic — another form of dropped traffic. And, with TCP, it can selectively drop the occasional packet as an indirect signal to slow down. With cooperative hosts, the router can try to accept reservations and hold bandwidth for applications that need it.
