w-apn
This command allows you to configure the W-APNs that can be connected through DeWAG, and the default-gateway
IP addresses to be used by the UEs for connecting to the W-APN network.

Syntax
w-apn apn_name default-gw ipv4/ipv6_address/maskbits +
no w-apn apn_name
no
If previously configured, removes the specified configuration.
apn-name apn_name
Specifies the APN name.
apn_name
must be the name of an APN and must be a string of 1 to 62 characters in length consisting of
alphabetic characters (A-Z and a-z), digits (0-9), dot(.) and the dash (-).
This value is compared against the subscribed APN returned by the AAA server or locally configured APN in
the subscriber-template configuration to find the default-gateway IP address to be used in DHCP signaling
packets.

default-gw ipv4/ipv6_address/maskbits
Specifies the IP address of the default gateway to be used by UE for W-APN access.
You can configure a maximum of four default gateways per W-APN. Multiple default-gateways are possible
as the APN can have different pools of different subnet with different default-gateway IP addresses.

ipv4/ipv6_address/maskbits
must be an IPv4/IPv6 address and subnet-mask, for example
192.168.1.1/24.
This value should be in the same subnet as that of UE allocated IP address from GGSN for the W-APN.
GGSN does not supply subnet-mask along with IP address. Therefore, the identification of whether GGSN-
allocated IP address is in same subnet or not is done with the help of configured “/maskbits”. This default-
gateway value is sent to the UE as default-gateway IP address using “Router” option in DHCP-OFFER
message. The maskbits is sent to the UE as subnet-mask using the “Subnet Mask” option in DHCP-OFFER
message.
