Using the Keyword no
To disable, delete, or return to default values, use the no form of the commands. For most commands,
if you type the keyword
no in front of the command, you will disable that command or delete it from
the running configuration. In this document, the
no form of the command is described in the “Syntax”
portion of the command description.
Syntax

| io-aggregator broadcast storm-control | snmp-server | username
}

Filtering show Commands
You can filter the display output of a show command to find specific information, to display certain
information only, or to begin the command output at the first instance of a regular expression or phrase.
When you execute a
show command, followed by a pipe ( | ) and one of the parameters listed below
and a regular expression, the resulting output either excludes or includes those parameters, as defined
by the parameter:
•
except— display only text that does not match the pattern (or regular expression)
•
find — search for the first occurrence of a pattern
•
grep — display text that matches a pattern
•
no-more — do not paginate the display output
•
save — copy output to a file for future use
The
grep command option has an ignore-case sub-option that makes the search case-insensitive. For
example, the commands:
•
show run | grep Ethernet returns a search result with instances containing a capitalized
“Ethernet,” such as interface TenGigabitEthernet 0/0
.
• show run | grep ethernet does not return the search result above because it only searches for
instances containing a non-capitalized “ethernet”.
•
show run | grep Ethernet ignore-case returns instances containing both “Ethernet” and
“ethernet”.
Version 8.3.17.0 Supported on M I/O Aggregator
Note: FTOS accepts a space before or after the pipe, no space before or after the pipe, or any
combination. For example:
FTOS#command | grep tengigabit |except regular-expression | find
regular-expression
