Branch switches.The Cisco switch can support any media as a trunk line. To achieve relay, you can use its unique isl tag. Isl (inter-switch link) is a protocol for transmitting vlan information and vlan data streams between switches, between switches and routers, and between switches and servers, by configuring isl encapsulation on the port directly connected to
The port rate between switches and switches, between switches and routers, does not meet the actual rate and requires tying more than two ports together to load balance and prevent single points of failure.1.

Overview of LAN switches
LAN switches have evolved from a HUB-based LAN shared in the traditional sense to a broader space. Take Cisco's Catalyst 5000 Series LAN switch as an example. It includes an integrated switching hardware structure, 10-Mbps Ethernet that supports switching, and-Mbps Fast Ethernet, supports fast Ethernet, FDDI, exchange-type ring, and layer-3 switching processing. This type of switch
to say, after you set the password for level 1, you will be asked to enter the password next time you connect to the switch and enter K, this password is the password set for level 1. Level 15 is the privileged mode password that you enter after you enter the enable command.
Step 2: Set the VLAN name. Because the four VLANs belong to different switches, the command for VLAN naming is VLAN 'vlan No. 'name' vlan name ', the following code configures VL
