cisco native vlan

with option 82 from the L2 switch and establish binding entries for the information . 　　Of course, if you encounter the switch does not support IP DHCP snooping information option allow-untrusted command can have the following two solutions:① using the IP DHCP relay information trusted(in-VLAN) command within an int VLAN of an unsupported switch② on the access layer switch to turn off the function of inser

Cisco switch in the VLAN how to add multiple ports at a time, this is usually used in the process of our configuration, because if one of the add port, the workload will be very large, so need to add multiple ports at once, the following by the small set of specific operations to introduce 1, first through the Consolo port or telnet to connect the switch to enter the user mode "", as shown in the picture:

Cisco device vlan, trunk, and Ethernet channel managementToday, we will introduce some common basic operations on cisco devices, such as creating VLANs, binding network cables, and using trunk and layer-3 switches. This is the topology of today: two three-layer switches, two PCs added with vlan10 and 20 respectively, and two three-layer switches with network redu

Today, we introduce some common basic operations of Cisco devices, such as creating VLANs, binding network cables, doing trunks, using three-layer switching, and so on.This is today's topology diagram: Two three-layer switching, two PCs, respectively, add vlan10 and 20, two three layers to do network redundancy, and finally achieve two PC communication, very simple, but the use of an experiment:650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M0

Experiment topological diagram Experiment Request: Using static route to realize network interoperability, using VTP management VLAN, using three-layer switching technology to achieve VLAN communication. Experiment steps: 1, using Visio to draw a topology map 2. Planning IP Address 3, using packet Tracer 5.0 for simulation experiment. Summary of Knowledge points: This experiment set involves stati
