Cisco Cisco Gigabit Ethernet Switch Module (CGESM) for HP Technical References

Use the show dtp privileged EXEC command to display Dynamic Trunking Protocol (DTP) information 
for the switch or for a specified interface.

show dtp [interface interface-id] [ | {begin | exclude | include} expression]

User EXEC

Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output 
are not displayed, but the lines that contain Output are displayed.

This is an example of output from the show dtp command:

Switch# show dtp

        21 interfaces using DTP

This is an example of output from the show dtp interface command:

Switch# show dtp interface gigabitethernet0/1
