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

Add Catalyst 5002 to the domain
You need to add Catalyst 5002 To The VTP management domain named cisco and set it to VTP client. It will receive VTP configurations and updates from the VTP server.
Note: by default, the Catalyst 5000 series switches are VTP servers.

Recently, the OS of a vswitch is old, so I want to update it. I want to ask a user to update the OS. After updating the OS, the problem occurs, I have a password for the OS. Since the password is being used and it is difficult for them to ask for it, I am ready to clear the password. After finding the relevant article on www.cisco.com, cleared successfully. Write down the cleanup process.
