One. Configuration principles 1. First determine the root Network bridge, based on the Network Bridge ID (consisting of the priority and MAC address) 2. Determine the root port. Specify port and passive port (determined by path cost, Network Bridge ID, port priority, Port ID) 3. You can enable the uplink port and speed port Two. Configure 1. Enable spanning tree on VLAN: Spanning-tree VLAN 2 2. Establish root Network bridge: (1) directly
In a Cisco switch, how does one configure QOS speed limit? How to restrict BT download? This blog will use detailed examples for your explanation.
Instance 1: QOS speed limit problem on CISCO switches
It is used to control the bandwidth of a leased line user on a vswitch. The vswitch is usually at 10/100/1000 or three rates. QOS is required for other rates. You can also limit some ports, policy to restrict

Cisco router configuration mode
In general, you can configure your router in 5 ways:
1.Console Port connection terminal or running terminal simulation software of the microcomputer;
2.AUX Port Connect modem, connect with remote terminal or computer running terminal simulation software by telephone line;
3. Via the TFTP server on the Ethernet;
4. Adoption of the Telnet procedure on the Ethernet;

I. Overview:
Cisco 15.2 iOS support IKEV2 IPSec VPN, security is more IKEV1, the first phase of authentication methods also have a variety of ways to support the local and remote use of different authentication methods, this test for both sides both local and remote use of preshared key method.
Two. Basic ideas:
The A.VPN peer is configured with a static VTI mode while the dynamic VTI mode is used.
B. The actual test found that the VTi interface c
The port Mapping method enables access to specific port services from the Internet to the local area network internal machines. For example, the machine you are using is in a LAN connected to the Internet, all the services you open on the machine (such as FTP), by default, the outside world can not access. This is because your IP is the LAN internal IP, and the outside can access only the server you are connected to the IP, because the entire LAN on the Internet only a real IP address, and this

There are many VPN products on the Cisco ASA Web VPN configuration market and their technologies are different. For example, in the traditional IPSec VPN, SSL allows the company to achieve more remote users to access the VPN in different locations, this service enables more network resources to be accessed and has low requirements on client devices, reducing the configu
