Today's recommendation: cisco switch module Ethernet application details, familiar with the following cisco switch module knowledge point, you only need to spend a few minutes to understand the cisco switch Module Settings. There is also a diagram below, and other related information will be mentioned in this article. As an important cisco switch modular multi-layer switch, the Catalyst 6500 series provides secure fusion services for cabling rooms, co
Understanding layer-3 Interfaces Layer-3 interfaces are classified into two categories: Physical Layer-3 interfaces and logical layer-3 interfaces. logical layer-3 interfaces include layer-3 VLAN interfaces and routing sub-interfaces. layer-3 VLAN interfaces integrate the routing and bridging functions; the physical layer-3 interface has only the routing function, which is equivalent to a traditional router. 1. layer-3 logical VLAN Interface The logical layer-3 VLAN interface provides a routing

configuring the switch via the console port is the most common and basic management and configuration that network administrators must master. The different types of switch console ports are located in the same location, some on the front panel (such as Catalyst 3200 and Catalyst 4006), and others on the back panel (such as Catalyst 1900 and
Some DHCP port settings are involved in this article. In its settings, Do you know some port problems? Configure the network environment of the DHCP server instance for a Cisco 3750 switch: A 3750 switch is divided into three VLANs. vlan2 is the network where the server is located, and the IP address segment is 192.168.2.0. The subnet mask is 255.255.255.0, gateway: 192.168.2.1. The Domain server is windows
Use Telnet to manage network devices This management mode requires the configuration of commands on the routing and switching devices, which is less than the command configured in the SSH management mode. The following figure uses the topology of Figure 1 as an example to configure the vswitch so that you can manage the PC and use Telnet to manage the configuration of Cisco 4506. The management VLAN 20 configuration on Cisco 4506 and Cisco 3750 is the
Failure phenomenon When the computer is unable to connect to the Internet, find the user's IP address from the document, try to ping several, and find all the connections timed out. Then, Ping the Library building's central switch is normal.

Application examples My school is a student apartment, PC owns about 1000 units. Using DHCP assigned IP address, with 4 C class addresses, the actual number of addresses available is about 1000. Because of the frequent presence of private DHCP servers in the building, a large number of hosts cannot be assigned to legitimate IP addresses, and because a significant number of hosts specify IP addresses, conflicts with DHCP-assigned IP addresses are caused. The above two aspects, all caused the apa
