Modify the script to include the IRLs. Enter the show nv edge data forwarding location 0/RSP0/CPU0
command in order to check the links.
set irl_list {{TenGigE 0/0/2/0} {TenGigE 0/0/2/1} {TenGigE 1/0/2/0} {TenGigE 1/0/2/1} }

Modify the script to include a Linux Telnet disconnect sequence. The octal value 35 is the equivalent of
a Ctrl-] key combination, which is used to gracefully terminate the console reverse Telnet connection and
allow the script to complete successfully. The modification should be around line 162 in the script.
proc router_disconnect { } {
global debug_mode
global connected_rack
if {$debug_mode == 1} { return }
send -- ?\35?
sleep 1
expect -exact "telnet> "
send -- "quit\r"
expect eof
set connected_rack -1
sleep 5
