How to Configure a VLAN Cisco Router

VLANs help to organize large networks.
Configure a VLAN on a Cisco Router by using a sub interface. CISCO2811-AC-IP The sub interface commands allow you to specify that the interface should encapsulate frames according to the IEEE 802.1Q standard. You can also specify a VLAN number.

Instructions
1
 Use the name and password given to you by your system administrator to log in.
Log on the router and enter enable mode using the standard user name and password assigned to you by your system administrator. Enter an enable password if required.

2
 Identify which interface will have VLANs.
Identify which physical interface will connect to the switch and which VLAN number is in use. It is possible that more than one interface will connect to VLANs. Record each interface and the VLAN numbers that will connect to it. As an example, let's assume VLAN 25 and 26 will connect to interface Fastethernet 0/0 and VLAN 78 will connect to Fastethernet 0/1.

3. Enter configuration mode by typing "configure terminal". The prompt will change from "Router#" to "Router(config)#".

4. Create or edit a subinterface. Type "interface fastethernet 0/0.1". CISCO2811-DC The prompt will change to "Router(config-subif)#". The "1" following a period after the interface number is the subinterface number. This command will create the subinterface if it does not exist or allow you to edit subinterface 1 if it does exist.

5. Configure the subinterface with IEEE 802.1Q encapsulation and enter one of the VLAN numbers. Use the command "encapsulation dot1Q 25" to set this subinterface to handle VLAN 25.

6
 The addresses for each VLAN will come from the network design.
Enter the IP address for this VLAN. Each router virtual interface will need a unique IP address as designed in your IP address layout. For example, enter the command "ip address 192.168.1.254 255.255.255.0". Both the address and the mask should come from your IP address design.
o    7
Enter "exit" to return to the main configuration prompt of "Router(config)#"

8. Configure the remaining subinterfaces on all required physical interfaces. Use the same commands but substitute the VLAN numbers and IP address from your network plan. In this example, enter "interface fastethernet 0/0.2", "encapsulation dot1Q 26", "ip address 192.168.26.254 255.255.255.0" and "exit" to configure the second VLAN. The last VLAN in our example would be entered using the command "interface fastethernet 0/1.1", "encapsulation dot1Q 76", CISCO2811-V/K9 "ip address 192.168.76.254 255.255.255.0", "exit". When all information is entered type "end" to exit configuration mode.

9. Verify the configuration by typing "show run" at the router enable prompt of "Router#". Make sure the commands were typed in correctly and the addresses and VLAN numbers match the numbers in your plan.

10
 Don't forget to save the configuration changes.
Save the configuration by entering the command "copy running-config startup-config".

Tips & Warnings
•    The commands shown here are spelled out in long form so they may be more easily understood. A proficient Cisco operator would abbreviate the commands.
•    For example, "configure terminal" would be abbreviated to "conf t"; "interface would be abbreviated to "int"; "fastethernet" would be abbreviated to "f"; "running-config" would be abbreviated to "run" and "startup-config" C2811-VSEC/K9 would be abbreviated to "start".
•    An alternative to the command "copy run start" is "wr me", meaning "write memory."
•    Remember that the changes you make take effect immediately.
•    Be certain you are editing the subinterface.
•    Deleted subinterfaces may not actually disappear until the the next reload.

How to Configure QOS on a Cisco 1841 Router


The Cisco 1841 router runs the Cisco IOS operating system and can be connected to by an authorized administrator using SSH on your network. Optimized for video data, the Cisco 1841 supports a full range of Quality of Service, or QOS, features that allow it to prioritize video traffic and ensure there is a reliable data stream for this form of Internet communication. In addition to its default prioritization of video data, you can prioritize specific ports on the cisco 1841 cost.
Steps to Configure QOS on a Cisco 1841 Router
1. Connect to your routeur cisco 1841 prix using SSH. Obtain the IP address from its parent router or your network administrator and open your preferred SSH client. Connect to it on the provided IP address with a port of 22.
2. Enter your administrative username and password when prompted, then press "Enter."
3. Type "qos enable <port1,port2,port3>" without quotation marks to add these ports to the priority list. precios router cisco 1841 Use a comma only if you have multiple ports and replace "port1," "port2" and "port3" with the numeric number of your application's port.
