How to flush whole entries of arp in one shot

[network_4]

Hi please let me know how to delete whole entries of arp in one shot as there are around 1000 entries and it's difficult to delete it one by one

Hi

Since there is no "flush" parameter to arp
you need to delete entries one by one:

Try:
$ for E in $(arp -a | sed "s/ .*//"); do
arp -d $E
done

Hi,

Use the below script to clear all arp cache entries in one shot -

#!/usr/bin/sh

for i in $(arp -a | awk '{print $1}')
do
arp -d $i
done

cheers!!
