Mac Table Aging

Wed Nov 10, 2021 10:28 pm

Is there a setting for mac table aging? From wiki I found that its about 5 min but I need to change it to about 10-15 min.
The problem I have is that my Splunk server witch is on ubuntu its almost silent on sending traffic and the mac address is removed from the Host tab after a period of time.
This results in a flood of UDP Syslog traffic to all ports and switches on that network. I know I can use the static mapping but I need to add this to multiple switches and remember it in case I want to move the VM to another host thats on a different port.

Have the host ping its default gateway every minute or so. Easy with a cron job or scheduled task.
