Using pattern matching with the
show interfaces custom command
If you have included a pattern matching command to search for a field in the output of the
show int custom command, and the
show int custom command produces an error, the error message may not be visible and the output is empty. For example, if you enter a command that produces an error (such as vlan is misspelled) with the pattern matching
include option, the output may be empty:
switch# show int custom 1-3 name [vlun|include vlan1]
Try the
show int custom command first to ensure there is output, and then enter the command again with the pattern matching option.
You can substitute
int for
interface; that is: show
int custom.
