CLI: Viewing a Summary of Switch Operational Data

Syntax: show tech

By default, the show tech command displays a single output of switch operat ing and running-configuration data from several internal switch sources, including:

■Image stamp (software version data)

■Running configuration

■Event Log listing

■Boot History

■Port settings

■Status and counters — port status

■IP routes

■Status and counters — VLAN information

■GVRP support

■Load balancing (trunk and LACP)
