Desktop. Desktop routers include routers that do not use special rack mounts and are suitable for placement on any suitable surface — a table, shelf, etc. Although there are quite advanced models among desktop devices, however, most of them have relatively simple functionality and are designed for use in small networks where an abundance of equipment is not required.
—
Rack mounted. Routers that are standard installed in a telecommunications rack are usually 19 "standard (although technically many of them can also be used as desktop ones, albeit with less convenience). Racks are used in extensive networks that require a large amount of equipment; accordingly, routers of this type in general, more powerful and advanced than the desktop, and are designed primarily for professional use.

To the mast. Installation on a mast or other vertical structure — a tower, a pole, etc. Quite a rare form factor; It is mainly used in waterproof models designed for the possibility of working outdoors. Mobile network capable devices in this category may have a directional antenna to improve connectivity.
The presence of a
console port in the router. This connector is used to control the device settings from a separate computer, which plays the role of a control panel — a console. The advantage of this format of operation is that access to the functions of the router does not depend on the state of the network; in addition, special utilities can be used on the console that provide more extensive capabilities than a regular web interface or network protocols (see "Management"). An RS-232 connector is often used as a console port, but in modern routers this role can also be played by a separate Ethernet input (not used for any other purpose).
Management methods and protocols supported by the router.
—
SSH. Abbreviation for Secure Shell, i.e. "Safe shell". The SSH protocol provides a fairly high degree of security, because. encrypts all transmitted data, including passwords. Suitable for managing almost all major network protocols, but requires a special utility on the host computer.
—
Telnet. A network management protocol that provides configuration via a text-based command line. It does not use encryption and does not protect transmitted data, and is also devoid of a graphical interface, which is why in many areas it has been supplanted by more secure (SSH) or more convenient (web interface) options. However, it is still used in modern network equipment — in particular, as a means of managing FTP servers.
—
Web interface. This function allows you to open the router's management interface in a regular Internet browser. Thus, to access the settings, you do not need special software — just a regular computer or even a smartphone / tablet is enough (modern mobile browsers are close to desktop ones in terms of capabilities).
—
SNMP. Abbreviation for Simple Network Management Protocol, i.e. "simple network control protocol". It is a standard part of the common TCP/IP protocol on which both the Internet and many local networks are built. I
...t uses two types of software — "managers" on control computers and "agents" on managed computers (in this case, on a router). The degree of security is relatively low, but SNMP can be used for simple management tasks.
Note that this list is not exhaustive — some routers have other, more specific management capabilities (such as the EEM event manager in Cisco devices).
