DWS-1008 User's Manual
6. The DNS server replies with the system IP address of an switch.
• If only TRPZ is defined in DNS, the AP sends a unicast Find DWS-1008 message to
the switch whose IP address is returned for TRPZ.
• If only wlan-switch is defined in DNS, the AP sends a unicast Find DWS-1008
message to the switch whose IP address is returned for wlan-switch.
• If both TRPZ and wlan-switch are defined in DNS, the AP sends a unicast Find
DWS-1008 message to the switch whose IP address is returned for TRPZ. The AP
ignores the IP address returned for wlan-switch.
• If both TRPZ and wlan-switch are defined in DNS, and the AP is unable to contact
the IP address returned for TRPZ, the AP never contacts the IP address returned for
wlan-switch. The AP does not boot.
7. The AP sends Find DWS-1008 requests to the DWS-1008 IP addresses given by the DNS
reply. If a DWS-1008 receives the Find DWS-1008 Request, the process continues with
step 8.
However, if no switches reply, the AP retries this method up to 11 more times:
• If the DWS-1008 replies after all 12 attempts, the AP begins the process again with
step 1 on the other AP port.
• If the other AP port does not have a link or the AP has only one port, the AP instead
restarts, and begins the process again with step 1 on the same AP port.
8. The DWS-1008 that receives the Find DWS-1008 request determines the best DWS-1008
for the AP to use, based on the bias settings for the AP on each switch. If more than one
switch has high bias for the AP or all switches have the same bias, the DWS-1008 suggests
the switch that has the highest capacity to add new active AP connections.
9. The DWS-1008 sends a unicast Find DWS-1008 Reply message to the AP containing the
system IP address of the best switch to use.
10. The AP sends a unicast message to the suggested switch, to request a software image
and configuration. If the AP does not receive a reply after 10 seconds, the AP reboots and
starts the boot process over at step 1.
If an AP does not receive a reply to a DNS request or a request for a system image and
configuration after one minute, the AP starts the boot process over with a new DHCP Discover
message, this time from AP port 2.
