In this case, the SM will append “<mac>.cfg” to the path and try to get that file. For example, if the SM’s
MAC address is 0a-00-3e-a2-c2-74, it will request for
ftp://10.120.163.253/smconfig/0a003ea2c274.cfg .
This mechanism can be used to serve individual config file for each SM.
Troubleshooting
1 Ensure that the___14 SM is running 13.3 or newer version of software.
2 If the SM has factory default config, confirm ICC is enabled on the AP, so the SM can
connect to it.
3 If the SM is connecting to the AP using a color code other than ICC, make sure the SM has
“Network Accessibility” set to “Public” and “DHCP State” set to “Enabled” in the
“Configuration > IP” page.
4 Make sure the golden config file does not turn off “Network Accessibility” or “DHCP State”.
If it does, the SM will no longer request the config file when it is rebooted.
5 Check the event log of the SM to see the status of the configuration file import including
any errors that prevented it from importing the file.
6 Capture the DHCP Offer packet from the DHCP server to the SM and verify that Option 66
has the expected URL.
