Using pattern matching with the show VLANs custom command

If a pattern matching command is in a search for a field in the output of the show vlan custom command and it produces an error, the error message may not be visible. For example, if you enter a command with the pattern matching include option that contains an error (such as 'vlan' is misspelled) as in the following example, the output may be empty:

switch(config)# show vlans custom 1-3 name vlun include vlan1

Hewlett Packard Enterprise recommends that you try the show vlans custom command first to ensure that there is output and then enter the command again with the pattern matching option.
