Device upgradtion consideration


Device up-gradation consideration these are thinks better to consider while upgrading the device with the newer one .
 
 Space
 power [ AC/ DC  / socket type ( C14/C15 - C19/C20 etc) 
 Rack type and mounting brackets and screws
 IOS  Feature comparison  does all the features supported in the newer image - double check [ sometime we downgrade the device eg: move the powerful device where most needed]
 Access to the technicians 
 Interface Type and fibre patch cords [ lc / sc / fc ] , length. 
 If we are swapping the device from different location make sure the transport and proper wrapping / cartons. 
 Then actual migration plan :) 

CCIE SP TCL IOS XR reachability Script with source address


Following Script will work to check the reach-ability in IOS XR with source address Execute
 
run tclsh
Then you can place the TCLSH commands :
 
set i "9.9.0.3"
foreach X {
9.9.0.1
9.9.0.2
} { ping -s $i $X }
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 9.9.0.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 9/11/19 ms
