Viewing Status Information¶
Status information can be viewed using the show command from either basic or
configuration mode.

The behavior of each show command is covered in relevant sections of the
documentation.
Output Modifiers¶
show commands support a limited set of output modifiers which are invoked by
adding a pipe character (|) after the command followed by one of the
supported modifiers and its arguments. These include:
| match <pattern>| exclude <pattern>| tail <num>| count
Warning
When using output modifiers there must be a space before and
after the pipe character (|). For example, a | b is valid, but
a|b is invalid.
Match¶
The | match <pattern> modifier filters the output to lines matching the
given pattern. The pattern supports some regular expression conventions such as
using . to match any single character, .* to match any string, and |
between multiple patters to match any of the given patterns.
Tip
Some pattern components may need a leading backslash, such as \. to match
a literal period character. The \ must be typed twice as the first press
escapes the second.
Example:
tnsr# show route table ipv4-VRF:0 | match 10\.30\.
10.30.0.1/24 via LAN weight 1 preference 0
10.30.0.1/32 via 10.30.0.1 local LAN weight 1 preference 0
10.30.1.1/24 via DMZ weight 1 preference 0
10.30.1.1/32 via 10.30.1.1 local DMZ weight 1 preference 0
Exclude¶
The | exclude <pattern> modifier filters the output such that it excludes
lines matching the given pattern.
Example:
tnsr# show route table ipv4-VRF:0 | exclude 10\.30\.
Route Table ipv4-VRF:0 AF: ipv4 ID: 0
-----------------------------------------
0.0.0.0/0 via 203.0.113.1 WAN weight 1 preference 0
10.15.30.2/24 via FIBER weight 1 preference 0
10.15.30.2/32 via 10.15.30.2 local FIBER weight 1 preference 0
203.0.113.30/24 via WAN weight 1 preference 0
203.0.113.30/32 via 203.0.113.30 local WAN weight 1 preference 0
Tail¶
The | tail <num> modifier filters the output so only the last <num>
lines of the output are returned.
Example:
tnsr# show route table ipv4-VRF:0 | tail 2
203.0.113.30/24 via WAN weight 1 preference 0
203.0.113.30/32 via 203.0.113.30 local WAN weight 1 preference 0
Count¶
The | count modifier does not print any of the output, instead it prints a
count indicating the number of lines in the output.
Example:
tnsr# show route table ipv4-VRF:0 | count
12
Note
The count also includes any leading or trailing blank lines in the output.
