Entering the above command sequence results in the following prompt:
[local]host_name(apn-profile-profile_name)#
Syntax
pgw-address ip_address [ s5-s8-protocol pmip ] [ weight weight ]
no pgw-address ip_address
no
Disables the P-GW address configured in this APN profile.
ip_address
Specifies the IP address for the P-GW in IPv4 dotted-decimal or IPv6 colon-separated notation.
s5-s8-protocol pmip
MME only. Configures the S5-S8 protocol for the gateway.
weight
weight
Specifies the weight (preference) assigned to the addressed P-GW for load balancing.
weight
is an integer
from 1 through 100 where 1 is the least preferred and 100 is the most preferred. If no weight is specified, the
P-GW address is assigned a default weight of 1.
If a weight is assigned to an address, the weights of the P-GW(s) (that are operational) are totaled, and then a
weighted round-robin selection is used to distribute new primary PDP contexts (for MME) or primary CPC
requests (for SGSN) or new PDN connections (for ePDG) among the P-GW(s) according to their weights. As
with all weighted round-robin algorithms, the distribution does not look at the current distribution, but simply
uses the weights to distribute new requests. For example, two P-GWs assigned weights of 70 and 30 would
distribute 70% of calls to one, and 30% to the other. The sum of all weights do not need to total 100.

Usage
Use this command to define load balancing to be applied during P-GW selection. A maximum of 16 P-GW
addresses can be configured for this APN profile.
