show system

Using the show system command, you can obtain a component status summary regarding the switch components. This information includes the system status, current traffic percentage, peak percentage, status of the fans, power supplies, and modem; uptime, and system identification configuration. There is no comparable command on the 1900EN series switches.

show test

The show test command can be used to obtain the status of the switch, interface cards, power supplies, Enhanced Address Recognition Logic (EARL) tests, or active loopback. It also displays the memory status of the read−only memory (ROM), flash electrically erasable programmable ROM (EEPROM), serial EEPROM, and non−volatile RAM. There is no comparable command on the 1900EN series switches.

show version

The show version command provides hardware and software version numbers, in addition to memory and the system uptime statistical information. This command can be used on both the Set/Clear IOS and the CLI−based IOS.

show vtp domain controller

The VLAN Trunking Protocol (VTP) maintains a consistent VLAN configuration throughout the network. In a VTP management domain, a configuration change is done only once on a VTP server−configured switch. The new configuration is propagated throughout the network. The show vtp domain controller command provides the status and configuration information for VTP.

Viewing the Set/Clear IOS Configuration

To view the Set/Clear IOS configuration, use the show config command. Let’s take a look at an example of the output from this command:
