Port Overview
Port 1-16 is the downlink port of an inline blade
Port 17-18 is a switch interconnect and is disable by default
Port 19 is for the blade on-board administrator.
Port 20-24 is the uplink port.
Connect to the console port of the switch
To access the switch locally:
1. Connect The switch DB-9 serial connector, using the Null-modem serial cable to a local client device (such as a laptop Computer) with VT100 terminal emulation software
startx start the x server. Then open xterm to lose.Into the echo "Hello,world" >/dev/console command, the string Hello,world is displayed on the first virtual terminal. You press CTRL+ALT+F1, go back to the terminal that started the X server, you can see the Hello, world string. Now it's time to understand the difference between the terminal and the console. To put it simply, the console is a direct connection to the computer's native device, the terminal is through the cable, network and s

Introduction SECURECRT is a terminal emulator that supports SSH (SSH1 and SSH2), simply the software that logs on to UNIX or Linux server hosts under Windows. SECURECRT supports SSH and supports both the Telnet and rlogin protocols. The SECURECRT is an ideal tool for connecting and running Windows, UNIX, and VMs. You can transfer encrypted files by using the included VCP command-line program. All features of the popular Crttelnet client include: Autoenrollment, different features for different h

Here we mainly analyze how to use the Cisco router configuration master port OSOLE to connect VT100 and compatible terminals, and pass Win 3.

How to log on to a Huawei router on a Super Terminal? Generally, we can use telnet commands to log on to a vrotelnet. Of course, this command can be used only after it is set, before that, we used the Super Terminal to log on through the Console port. This is what we will talk about below.1, physical connection 1, the configuration of the cable DB-25 plug to the computer to configure the router serial port. 2. Connect one end of the RJ-45 of the configured cable to the Console port of the router

So how can we establish a connection with a remote server? There are two ways to achieve this:
Method 1: Open the "run" dialog box in the "Start" menu and enter the Telnet
