About ARP table

arp

#1

Hello,

I have a question.

How long the time does vyos hold arp table?

I want to know the time to flush arp table.

Regards,

It’s probably the same as Debian, which Googling says defaults to 60 seconds and is set by the gc_stale_time sysctl.
No idea if that’s correct or how to flush it.

vyos@sh-bdr-vyfw:~$ cat /proc/sys/net/ipv4/neigh/eth1/gc_stale_time 60

Thank you for your reply.

I understood that there are no functions about arp flush.
