TCL Script to get MAC to IP and connected port

I have used simple image to test and it works fine

below IOS i have tested in my LAB.

Here is the steps

INET#tclsh
INET(tcl)#puts [open “flash:tcl_script1.tcl” w+] {

PASTE here your TCL Script to run

#############
foreach ip $::argv {
set result [exec “show arp | inc $ip”]
if [regexp {[a-zA-Z]+\s+\d+\.\d+\.\d+\.\d+\s+\d+\s+([0-9a-f]+\.[0-9a-f]+\.[0-9a-f]+)\s+ARPA} $result match mac ] {
set output [exec “show mac address-table address $mac”]
regexp {(\d+\s+[0-9a-f]+\.[0-9a-f]+\.[0-9a-f]+\s+[A-Z]+\s+[0-9\/a-zA-Z]+)} $output match output
puts “$ip = $output”
} else {
puts “$ip not in arp table”

}}

########

}  – To close the script

INET(tcl)#tclquit
INET#

here is my test

It works, simple for day to day life of DevOps.

I am going to create another one..which collect all MAC address and IP and port information stored in Database, so Engineer can pull the data when ever required

happy labinnggggggggggggg !
