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.

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

The ios version must be consistent with the dedicated stack module and stack cable, and the maximum number of stacks is 9.
Ii. Stack advantages:
High-density ports, easy to manage, and stacked switches can be regarded as a unified configuration of a

Iii. Stack instances:
1: The stacked cables are physically connected. The connection method is master stack1, which is connected to slave stack2.
2: enable the master without any configuration. .
3: Server Load balancer is enabled.
4: No configuration is required. Line plug, automatic stacking election upon startup, master is highlighted)
