Hi,
can anyone explain whats the difference between the Idle Time and the Host Dead Time?
Idle is explained by Mikrotik-Wiki:
idle-time (read-only; time) : time user has been idle
Unfortunately Host Dead Time is not explained and it differs sometimes (not always) from Idle:
Indeed! I cannot find any information about the Host Dead Time so I cannot give any differences about these two. Where did you heard about it? bubble shooter
Its under Hotspot → Hosts - you can add the column “Dead Host Time”:
I investigated and found something in an old ROS V2.9 documentation:
https://www.manualslib.com/manual/491908/Mikrotik-Routeros-V2-9.html?page=530
host-dead-time(read-only: time) - how long has the router not received any packets (including ARP replies, keepalive replies and user traffic) from this host
Now, the question is, why differ the Idle-Time and the Host-Dead-Time sometimes?
I did a few tests and it seems Idle-Time refers to “user traffic” only - not network traffic data itself. As an example, if I ARP-request the host (ARP-Ping, I’d consider ARP as “network traffic”, not “user traffic”), I will get an reply, the Host-Dead resets but the Idle does not. If the Host leaves the wifi-coverage area, Idle and Host-Dead are the same. But it seems if the Host does simply nothing, but some network related stuff goes on (ARP…), the Idle counts up, but the Host-Dead resets.
One question remains, why has Mikrotik purged this from their current documentation?
