Command History
Usage Guidelines The show interfaces capabilities command with different keywords has these results:
• Use the show interface capabilities module number command to display the capabilities of all
interfaces on that switch. If there is no switch with that module number, there is no output.
• Use the show interfaces interface-id capabilities to display the capabilities of the specified
interface.
• Use the show interfaces capabilities (with no module number or interface ID) to display the
capabilities of all interfaces.
• Use the show interface switchport module number command to display the switch port
characteristics of all interfaces on that switch. If there is no switch with that module number, there
is no output.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.
Examples This is an example of output from the show interfaces gigabitethernet0/1 command:
Switch# show interfaces gigabitethernet0/1
GigabitEthernet0/1 is up, line protocol is up
Hardware is Gigabit Ethernet, address is 0002.4b29.4401 (bia 0002.4b29.4401)
MTU 1500 bytes, BW 100000 Kbit, DLY 10 usec,
