There are still many things worth learning about Cisco switches. Here we mainly introduce the Cisco switch interface mode. In a Cisco switch network, there are four main types of interfaces in the LAN that are ultimately stable: access/trunk/multi/dot1q-tunnel. 1. access: it

The naming rules for Cisco switches are more complex than the naming rules for routing,Look at these:ws-c2960-24tc-l, WS-C2950G-24-EI-DC, Ws-c2960-24tt-l, Ws-c3750g-24ts-e, Ws-c3750g-24t-s, We didn't find them on the switch, we just saw the Catalyst 2950 series and wrote it all: The Cisco Catalyst 2950 Series, which means the

In Cisco networks, there are four main types of interfaces in the final stable state of a switch in a LAN: Access/trunk/multi/dot1q-tunnel.1, Access: Mainly used to access terminal equipment, such as PC, server, print server and so on.2, Trunk: Mainly used to connect other switches, in order to host multiple VLANs on the line.3. Multi: Hosts multiple VLANs in one line, but unlike trunks, it does not label t
