BreezeCOMPACT Full Configuration via CLI
In the case of a restart on one of the EPC entities, after that EPC recovers, eNBs will force all
the sessions to it until the load between all the entities is proportionally aligned.
In the case eNB switched to work with the Secondary MME pool, the UE sessions forwarded to
"secondary" MME entities will stay there until UE disconnection. After the recovery of the
primary, in a new UE Attach, eNB will perform the new balancing decision, forwarding the
new coming UEs to one of the Primary MME entities. There is a manual operational command
on eNB that enables an operator to force disconnection of UE sessions on Secondary MME
entities to move to the primary.
Following the settings. This should be running from BreezeCompact% prompt:
 set networking s1-signaling-servers-list 172.16.81.144 mme-load-balancing-
priority Primary
 set networking s1-signaling-servers-list 172.26.20.70 mme-load-balancing-
priority Secondary
For load balancing - configure MMEs within the same group (Primary or
Secondary)
For Fail over – configure at least two MMEs (one in primary group and one in
secondary group)
Show MME settings:
BreezeCompact% show networking s1-signaling-servers-list
s1-signaling-servers-list 172.16.81.144 {mme-load-balancing-priority Primary;
}
s1-signaling-servers-list 172.26.20.70 { mme-load-balancing-priority Secondary;
}
Note, in case the primary fail consequently all the UEs which associate with the primary MME
automatically will registers with the secondary MME. When the primary MME will come up
the UEs that are connected to the secondary MME will not move back to the primary MME
unless the operator will initiate the following command:

Use Bearer Interface as External Management Mode
If a single interface is used for both bearer traffic and management, you must select the B
Bearer
Interface as External Management
M
Mode
option. In this mode, only the bearer VLAN is used
and external management parameters are ignored.
Do not use this mode when using the BreezeWay2020, as the Management and
Bearer must be defined on different VLANs.
To enable this mode, enter the following command at the B
BreezeCompact%
prompt:
 set networking external-management use-bearer-ip-address true
To disable this mode (the default mode), enter the following command at the B
