8.4 DHCP status
Information on the activities of the DHCP server can be accessed by selecting the DHCP
status
item. The DHCP server provides automatic configuration of devices connected to the
network managed router. DHCP server assigns to each device’s IP address, netmask, default
gateway (IP address of router) and DNS server (IP address of router).
For each configuration, the
DHCP status
window displays the following information:
Item Description
lease Assigned IP address
starts Time of assignation of IP address
ends Time of termination IP address validity
hardware ethernet Hardware MAC (unique) address
uid Unique ID
client-hostname Computer name
Table 18: DHCP status description
In the extreme case, the DHCP status can display two records for one IP address. That
could have been caused by resetting of network cards.
Figure 19: DHCP status
Note: Starting with firmware 4.0.0, records in the DHCP status window are divided into two
separate parts – Active DHCP Leases (Primary LAN) and Active DHCP Leases (WLAN) .
