command to compare the information in

running memory to the information stored in non-volatile
memory.

• This command displays settings for key command modes. Each

mode group is separated by “!” symbols, and includes the
configuration mode command, and corresponding commands.
This command displays the following information:

- SNMP community strings

- Users (names and access levels)
- VLAN database (VLAN ID, name and state)

- VLAN configuration settings for each interface

- IP address configured for VLANs
- Routing protocol configuration settings

- Spanning tree settings

- Any configured settings for the console port and Telnet
