Replacing APs
To assign a channel, use the Dot11Radio interface command channel. With the Web
UI, configure a channel by clicking Configuration > Wireless > Radio, select a radio
and then select a Channel from the drop-down list.
Replacing APs
If you are replacing existing APs with a newer model of APs, use the swap ap
command to ease the task of updating your site’s AP settings. To use the swap ap
command, you need the MAC addresses of the new and old APs. There are two ways
to determine a MAC address. You can check MAC addresses of the APs to be replaced
with the show ap command. You can also look on the back of any AP for the MAC
address. The serial number is displayed on the label, below the bar code. The last 12
digits of the serial number is the AP MAC address.
The swap ap command equates the MAC address of an AP that you want to replace
with the MAC address of the new AP. By linking the numbers to an AP ID in the replace-
ment table, the system can assign the configured settings from the old AP to the new
AP. The settings that are tracked are the channel number, preamble, and power
settings. After inputting the swap information, use the show ap-swap command to
double check the AP MAC settings before physically swapping the APs.
Once you have double-checked the MAC addresses, take the old APs offline by discon-
necting them from the system. Replace the APs. When the APs are discovered, the
replacement table is checked, and the changes are applied to the new APs. Once the
new AP has been updated, the entry is removed from the replacement table.
To summarize the steps to replace the APs:
meru-wifi (config)# do show ap (gets the serial numbers of the APs you are replacing)
meru-wifi (config)# swap ap 00:oc:e6:00:00:66 00:CE:60:00:17:BD
meru-wifi (config)# exit
meru-wifi# show ap-swap
AP Serial Number New AP Serial Number
00:0c:e6:00:00:66 00:ce:60:00:17:bd
AP Replacement Table(1 entry)
meru-wifi# show ap (Disconnect the old APs and make sure they show Disconnect/offline
status)
Note: Replacing one AP model with another usually preserves the settings of the
original configuration. A newer AP may have settings that the older one does not;
those settings will be set to the default.
Caution! Despite the fact that some AP settings and configurations can be carried over
when replacing an AP, users cannot simply replace an AP300/AP400 with a different model
(such as an AP1000). The two models have very different capabilities and configuration
specifications and should not be considered synonymous.
