• secondary: Configures the secondary static FQDN string. The primary FQDN will be tried before trying
the secondary FQDN.
• default: Returns the command to default setting of pgw fqdn.
• no: Disables the pgw fqdn command if it was previously enabled.
If the above CLI command is not configured then the HSGW uses DNS to select the serving P-GW. The
HSGW receives a list of all the P-GWs that serve the given APN. Then, the HSGW compares a list of
P-GWs with the locally configured FQDN and selects the best matching P-GW.
