Cisco Nexus – Ping Sweep

The following script can be utilized to execute a ping sweep of a /24 network on Cisco Nexus switch. This has been tested and verified on Cisco Nexus 7K running 6.2.8a code version.

Actual script:

tclsh
for {set i 1} {$i < 255} {incr i} {
cli "ping 192.168.1.$i count 2 time 1 vrf VRF_A"
}

Script execution on a Cisco Nexus 7000 switch:

N7K_SW1# tclsh
N7K_SW1-tcl# for {set i 1} {$i < 255} {incr i} {  
> cli "ping 192.168.1.$i count 2 time 1 vrf VRF_A"
> }

Similar script but copy/pasting specific IP addresses:

tclsh
foreach address {
> 10.90.55.97
> 10.90.55.98
> } { cli ping $address count 2 time 1 vrf VRF_A }
