-remote management of routers-

-

A: router remote connection configuration:

The remote management of the router needs to meet the following conditions:

1. External interface: ip address

2.line vty login password and login login behavior.

3.PC can ping with ip.

Telnet: connecting remote Devic

Telenet ip

Sh ip int brief: see what interfaces the device has and how it is connected.

Quit: log out of the remote vty login.

The router displays telnet connections:

Show sessions on A router: who am I connecting with

Show users on B router: who is connecting with me?

-

B: (eject) suspend and resume telnet session:

X: suspend the last telent session and return to the local router or switch

Remember: 1. Press and hold Ctrl-Shift-6 at the same time, then let go, and press the X key: (suspend the telnet session temporarily and return to the local router or switch to configure the local router or switch).

two。 Press enter twice in a row to return to the telnet session: (you can also configure the telnet remote router or switch).

Note: suspending does not mean exiting the link, but temporarily returning to the original link.

-

C: log out of remote login:

Exit: means to end a remote telnet session and return to the local switch or router.

Disconnect: end a tenlet session from the local device. If you have more than one session, use the disconnect session sessionnumber command to close the session you want.

Clear line: indicates that the telnet session is closed from the external host, that is, by the recipient of the telnet.

Clear line link number: strip out the telent of that link.

-

D: use the ping and trace (path tracing) commands:

All belong to the icmp protocol.

Ping: test connectivity to remote devices.

Trace: the path that the test took.

-- start-up and configuration management of routers--

-

A: router Appliances / Startup sequence:

1. Complete the POST (plus a little self-test).

two。 Load and run the Bootstrap (bootstrap) code. (what startup mode, minimize startup, etc.)

3. Discover the Cisco IOS software.

4. Load the Cisco IOS software.

5. Look for the configuration file for the router.

6. Load the configuration file for the router.

7. If the above is done correctly, then the boot is complete.

B: internal components of the router:

1.RAM: memory.

2.ROM: read-only memory (devices that put some self-test).

3.Flash: put the IOS system (equivalent to a hard disk).

4.NVRAM (Configuration Register): put the configuration file and startup configuration values (bootstrap code).

5.Interfaces: interface.

6.CPU: the maintenance cost is high.

C:ROM (self-reading memory) function:

1.Bootstrap: the function is to read the value of the register and to control how the configuration file for IOS is loaded.

2.POST: self-check behavior.

3.Mini IOS software file: minimum IOS. When the IOS is damaged, you can enter the minimum IOS.

4.ROM Monitor:ROM monitoring mode (for password recovery), press Ctrl+Break or continuous switching power supply 3 to enter this mode.

Show verson: displays 1, 2, 3, 4 messages.

D: load the IOS software from Flash (flash memory):

In general, flash files are extracted into RAM.

You can use the boot system command to change the boot order.

E: configuration register value:

The value can be viewed through show version.

Config-register value: modifies the register value. The last 4 bits of the value are the startup setting bits.

0x2102: normal startup value.

0x2142: the nvrom configuration is not called, and is generally used when changing passwords.

F:flash command:

Show flash: view flash information.

Size, read-only, ios version and other information.
