You can configure and view the following parameters within the DHCP Server Configuration screen:
•

Enable DHCP Server: Place a check mark in the box provided to enable DHCP Server functionality. 

You cannot enable the DHCP Server functionality unless there is at least one IP Pool Table Entry configured.

•

Subnet Mask: This field is read-only and reports the Access Point’s current subnet mask. DHCP clients that 
receive dynamic addresses from the AP will be assigned this same subnet mask.

•

Gateway IP Address: The AP will assign the specified address to its DHCP clients.

•

Primary DNS IP Address: The AP will assign the specified address to its DHCP clients.

•

Secondary DNS IP Address: The AP will assign the specified address to its DHCP clients.

•

Number of IP Pool Table Entries: This is a read-only field that reports the number of IP address pools currently 
configured.

•

IP Pool Table Entry: This entry specifies a range of IP addresses that the AP can assign to its wireless clients. 
The maximum number of entries allowed is 20. Click Add to create a new entry. Click Edit to change an existing 
entry. Each entry contains the following field:
–

–

Default Lease Time (optional): The default time value for clients to retain the assigned IP address. DHCP 
automatically renews IP Addresses without client notification. This parameter supports a range between 3600 
and 86400 seconds. The default is 86400 seconds.

–

Maximum Lease Time (optional): The maximum time value for clients to retain the assigned IP address. 
DHCP automatically renews IP Addresses without client notification. This parameter supports a range 
between 3600 and 86400 seconds. The default is 86400 seconds.

Comment (optional)

Status: IP Pools are enabled upon entry in the table. You can also disable or delete entries by changing this 
field’s value.

You must reboot the Access Point before changes to any of these DHCP server parameters take effect.

The Link Integrity feature checks the link between the AP and the nodes on the Ethernet backbone. These nodes are 
listed by IP address in the Link Integrity IP Address Table. The AP periodically pings the nodes listed within the table. 
If the AP loses network connectivity (that is, the ping attempts fail), the AP disables its wireless interface until the 
connection is restored. This forces the unit’s wireless clients to switch to another Access Point that still has a network 
connection. Note that this feature does not affect WDS links (if applicable).
You can configure and view the following parameters within the Link Integrity Configuration screen:
•

Enable Link Integrity: Place a check mark in the box provided to enable Link Integrity. 

•

Poll Interval (milliseconds): The interval between link integrity checks. Range is 500 - 15000 ms in increments of 
500 ms; default is 500 ms.

•

Poll Retransmissions: The number of times a poll should be retransmitted before the link is considered down. 
Range is 0 to 255; default is 5.

•

Target IP Address Entry: This entry specifies the IP address of a host on the network that the AP will periodically 
poll to confirm connectivity. The table can hold up to five entries. By default, all five entries are set to 0.0.0.0. Click 
Edit to update one or more entries. Each entry contains the following field:
–

–

Status: Set this field to Enable to specify that the Access Point should poll this device. You can also disable 
an entry by changing this field’s value to Disable.
