This optional string parameters defines how 3GPP AAA Server strips MAC address of wireless LAN access point if it is embedded in the username. Some user equipment sends username in format such as 0234031234567890@00-11-22-33-44-55:nai.epc.mnc003.mcc234.3gppnetwork.org where 00-11-22-33-44-55: is not part of the username as specified by 3GPP TS 29.273. If ePDG or other network device can not be configured to remove the MAC address, 3GPP AAA Server can be configured to do so.

This option is not set by default and nothing is stripped. The only currently allowed value is colon, which removes everything starting after @ and ending with the first :.

# Our ePDG can not strip MAC addresses
StripMACFromUserName colon
