Layer-3 Ethernet switch: introduces L2 VLAN forwarding, configurations in layer-3 Ethernet switches, MAC addresses, and L2 VLAN forwarding, I hope you will have a clear understanding after reading the following articles. The forwarding mechanism of a layer-3 Ethernet switch is divided into two parts: layer-2 forwarding

K CommandLine is a command line, much like a router that uses commands to configure and monitor routers, mainly through

VLAN configurations in NVRAM, however, the VLAN information transmitted by other layer-3 switches in The VTP domain can be synchronized. Transparent mode: You can create, modify, or delete a VTP domain, or transmit the VTP broadcast information sent by other layer-3 vswitches In The VTP domain, but it is not involved in the synchronization and allocation of The VTP domain, it does not pass its own

C-F6. Multi-VLAN configuration DHCP? C3750-E? CISCO switches, c-f6c3750-e C-F6. Multi-VLAN configuration DHCP? C3750-E? CISCO switches. After VLAN and interface are allocated according to our plan, we need to consider which VLANs need to be configured with the DHCP service.

During hard disk data sorting, we found the original dtp vlan jump experiment video, which includes DTP protocol data packets, test tools, videos, and lazy. The following are the steps. Download the video and watch it. It was very casual. At that time, I kept it for reference. Implementation of VLAN jump attacks I don't talk much about it. I only find such a term on the Internet. No one has told me the

A comprehensive case of Cisco inter-VLAN routing and HSRP topology Description: www.2cto.com 1. R3 and R4 simulate the customer's pc, which belong to vlan10 and vlan20 respectively. Vlan10 and vlan20 represent different departments in reality. 2. SW1 is a layer-3 switch, and SW2 is a layer-2 switch. 3. R5 simulates the

Its VLAN configuration only affects itself.The switch is in Server mode by default.4) create a

interconnected with layer-3 switches. When using a router to connect to a vrovlan, you generally need to set sub-interfaces corresponding to each VLAN on the LAN Interface, while a layer-3 Switch generates a "VLAN Interface" internally )". A VLAN interface is an interface used to send and receive data from each

I have just been familiar with the basic configurations of the VLAN division experiment of the switch VLAN division configuration (PT simulator). I am not familiar with this knowledge for too long. Please forgive me for any errors, this configuration is for you to learn about the Cisco simulator configuration case. Www

The cluster connection options for the CISCO switch 2950 include Ethernet, fast Ethernet, fast Ethernet, and Gigabit Ethernet connections. Because it is not technically limited by dedicated stack modules or stack cables, CMS ex
