Question on: sh int status | include (port|fa0/13)

ciscofun

Dear all,
i just started working on my IE workbook Vol.1 , and found a question that would like to ask, below is what i need help on.

on Page.4 under the "Bridging and Switching"
1. there is a command call : sh int status | include (port|fa0/13),
what does the "|" and the "include (port|fa0/13)" means, how does it works ??

2. i followed the workbook to type this command, but nothing comes out from the switch, which does not match the outcome of the workbook's after running this command... but i checked all the commands in my switch are correct.

below is the outcome captured from my 3550

R12_Switch#
R12_Switch#
R12_Switch#sh int status | include (port|fa0/13)
R12_Switch#sh int status | include (port|fa0/13)
R12_Switch#sh int status | include (port|fa0/13)
R12_Switch#
R12_Switch#



can any one advice ? Thank you.

The pipe ( | ) means to take the results of the first command and redirect the output to the second command (in this case i which is short for include). Sorta like grep from linux. That and the "do" command are some of the best ever.

You would use it like

router(config-router)#do sh int stat | i fastethernet 0/0

Here is another example

Cisco-gw(config-router)#do sh ip int bri | i Fast
FastEthernet0/0 192.168.1.3 YES NVRAM up up

Cisco-gw(config-router)#

In the 2nd part, the | means OR

You want to include only the output lines from the show interface status command that includes the words Port (so that you get the "header line" for the output) OR the interface that you are interested in -- Fa0/13


The reason you're not getting any output is because the "match option" is case sensitive.

S3550-1#
S3550-1#sh int status | include (port|fa0/13)
S3550-1#sh int status | include (Port|Fa0/13)
Port      Name          Status       Vlan       Duplex  Speed Type
Fa0/13                  connected    trunk      a-full  a-100 10/100BaseTX
S3550-1#

Use Port instead of port and Fa0/13 instead of fa0/13

Also - the command will work with or without the parentheses.

Dammit, Mike! I've been trying to make that command work for the past year, or so, with no results. I keep thinking, "one of these days, I'll experiment with it and figure it out", sort of lazily and without too much effort put into it. . . and there you go, ruining what could have been several hours of hair-pulling and swearing, possibly even the kicking of more than one router.

Thank you guys !!!! i got it !!

case sensitive !! never thought of that !! thanks Mike !!!

I LOVE that one whenever I just want to find one thing in a running config when the device has a configuration a mile long...it really saves some time and tabbing!

Inc

For running config I use "sh run int <int><mod>/<port>"

dc-sw00#sh run int vl1
Building configuration...

Current configuration : <some number> bytes
!
interface Vlan1
<configuration>
end

also "sh run | section <string>" helps.

Result will be configuration blocks where case sensitive search string has matched.

Router#sh run | s FastEthernet0
interface FastEthernet0

interface FastEthernet0.24979

I like using the carrot ^ as well especially for syslog events. It allows you to specify what the line begins with

Anyone else use the "/" to search through sh run?
