No Tclsh? No Problem!

I’m shocked and appalled to have just discovered my 3550’s don’t support scripting with tcl. Actually, the 3560’s don’t either. But, thanks to a posting on CCIE Pursuit Blog a macro can be used to substitute a tcl ping script. The macro needs to be run in global configuration mode so you’ll need to include the ‘do’ statement.

  DLS1(config)#macro name TEST
  Enter macro commands one per line. End with the character '@'.
  do ping 172.16.1.1
  do ping 172.16.1.101
  @

  DLS1(config)#macro global apply TEST
  Type escape sequence to abort.
  Sending 5, 100-byte ICMP Echos to 172.16.1.1, timeout is 2 seconds:
  !!!!!
  Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
  Type escape sequence to abort.
  Sending 5, 100-byte ICMP Echos to 172.16.1.101, timeout is 2 seconds:
  !!!!!

  DLS1#show parser macro name TEST
  Macro name : TEST
  Macro type : customizable
  do ping 172.16.1.1
  do ping 172.16.1.101
