NOTE

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:

–Start IP Address

–End IP Address

–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.

NOTE

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

Link Integrity

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:

–Target IP Address

–Comment (optional)

–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.
