R94 Description of the menu options

The entries in the ARP table might, for example, have the following appearance if different devices with different IP addresses (192.168.139.20, 192.168.130.30) communicated with the router:

IP-address

Node-ID

Last-access

Connect

192.168.130.20

0000c0717860

6780443 tics

local

192.168.130.30

0800091eebf4

ARP-aging-min.This option allows you to enter a time (from 1 to 99 minutes) at the end of which the ARP table is automatically updated, i.e. all IP addresses that have not been accessed since the last automatic update are removed. The default setting is 15 minutes.

TCP-aging-min.If data transfer stops during a TCP connection to the router, e.g. if the user does not enter any more data during the remote configuration, it will automatically release the TCP connection on expiry of the time entered here. Possible settings are from 1 to 99 minutes; The default setting is 15 minutes.

TCP-max.-conn.The maximum number of allowable connections possible at the same time can be set here. DEFAULT setting is '0', meaning the same as “any number“.
