3. Create dynamic aggregation
Switch(config)#interface range g0/21-22
Switch(config-if-range)#channel-group 1 mode active
Switch(config-if-range)#exit
4. Create a link type
There are three types of link Ethernet port: Access, Hybrid, Trunk. Access types can belong to a VLAN ports, ports for connecting PCs; Trunk port can belong to more than one VLAN, can receive and transmit packets of a plurality of VLAN, ports between switches generally used; Hybrid type of port can belong to more than one VLAN, can receive and transmit packets of a plurality of VLAN, the switch can be used to connect and to be connected to a computer user. Trunk Hybrid ports and ports that is different from the Hybrid port allows the packets of the plurality of VLAN transmitted without tags, and Trunk port only allows packets from the default VLAN is transmitted without tags.
Table 1-9 link type of the Ethernet port
Operation
Command
Set the port Access Port
Switch (config) #interface Range G0 / 21-22
Switch (config) #switchport MODE Access
is provided as a Hybrid port
Switch (config) #interface Range G0 / 21-22
Switch (config) #switchport mode hybrid
set as Trunk port port
Switch (config) #interface Range G0 / 21-22
Switch (config) #switchport MODE Trunk
link type recovery port is the default port Access
undo port link-type
three types of ports can co-exist on the same switch, but between Trunk and Hybrid ports can not be directly switched, only Access port, then to another type port. For example: Trunk port has to be set to the Hybrid port, you need to use Access port, then a Hybrid port.
By default, the port is Access port.
Note that: Access port to a VLAN must already exist and can not be the default VLAN; Hybrid port to the VLAN must already exist; Trunk port to a VLAN can not be the default VLAN.
Implementation of this configuration, the Ethernet port can forward packets of the specified VLAN. Hybrid and Trunk port can be added to more than one VLAN in order to achieve the same VLAN and VLAN communicate on the end of the switch on the switch. Hybrid port VLAN packets which can also be set to tag, which without tags, provide a foundation for the implementation of the different processing flow for different VLAN packets

select a PC, a device (switch, router line)
connection and PC equipment, cable select blue cable, English should be a console --- meaning the console. Connection, select the RS232 interface on the PC, select CONSOLE interface on the device
Once connected, double-click the PC icon, a window opens, click on the desktop (desktop), and then select the terminal (terminal), click OK, on it!

20. Cisco mode
Oh finally found a question about the cisco up.
Hello friends, I use my own language Ha, ha a little long, but it will help you learn to Kazakhstan. Cisco router user interface are the following:
1. The user performs mode (the User EXEC Mode)
2. privileged execution mode (the Privileged EXEC Mode)
3. Global Mode (Free Join the Configuration Mode)
4. monitor mode (ROM Monitor Mode) An BREAK + Ctrl
5. the installation mode (setup mode) to enter privileged mode line setup
6.Boot mode (RXBoot mode)
1, 2 and 3 are used. Here I will formally answer you asked.
Router a boot, go in the interface prompt is ">", like this child Ha, "Router>" This is the user EXEC mode, also the lowest level mode allows only a limited number of basic monitoring commands in this mode command will not allow any change in the router configuration.
What should we do Zenong To configure the router, then you have to come into the "privileged execution mode" of (that is, enter "enable" command in user EXEC mode). It appears like the prompt "#", such as "Router #". Compared user EXEC mode, which offers more commands and privileges, such as debug commands, and more detailed testing.
As for the "Global Mode", it is the configuration (global) system and a corresponding configuration details (such as IP interfaces, the routing protocol) when the incoming interface, the stuff in this configuration is the overall impact. Global Configuration Mode prompt like this "(config) #", for example, I cite here the example in respect of a "Router (config) #".
And to configure specific stuff must enter from the global configuration mode corresponding to the sub-configuration mode. For example:
Router (config-IF) // # specific interface configuration
Router (config-line) # // line mode configuration, such as the console and vty Ha
Router (config-router) # // router mode, such as a routing protocol Time
Baidu does not know replies not powerful enough, or I can re-mark and more beautiful typography, so that friends more easily understood.
A brief summary of your next question is, privileged execution mode is primarily used for debugging global configuration mode is used to configure. And their relationship, to reach global configuration mode, you have to come at the privileged EXEC mode Kazakhstan.
While the corresponding command Kazakhstan see below:
Router>
Router> enable // execution mode from the user to enter the privileged EXEC mode
Password: // If you set a password privileged EXEC mode, then have to enter a password when entering Kazakhstan
Router #
Router # // Exit from the privileged EXEC mode return to the user EXEC mode
Router>
// Here I demonstrate how to get global configuration mode from user mode to perform a step by step Ha:
Router> enable
Router #
Router # the configure Terminal
