Sending bunch of commands from txt file in Expect

Question

How to send bunch of commands to Cisco router from txt file like:

configure
class-map match-any popc_fiberpower004_booster_v4
 match access-group ipv4 bng_permit_v4
 match access-group ipv6 bng_permit_v6
end-class-map
policy-map popc_fiberpower004_booster_v4_in
 class popc_fiberpower004_booster_v4
  police rate 110 mbps
  set dscp 0
 class class-default
end-policy-map

And of course from Expect script via telnet. Thank you in advance for help.

Answer 1

Note that expect is an extension of tcl, so you'll want to use some Tcl commands

• open
• while
• gets

You might find the Tcl tutorial helpful, particularly the File Access 101 section.
