5. - SBC Steering pool

With the current configuration Oracle SBC is now able to process signaling but there are two problems, first there are no resources to manage audio and there is no routing in place to process the session correctly.

Let’s fix the problem about the resources adding steering pools associated with the Internal and External realms.

Adding steering pools resources must be associated with the number of sessions to be supported and needs to be consider ports for video and RTCP. For this lab environment we will add only 101 ports.

PCOSBC# config t

PCOSBC(media-manager)# steering-pool 
PCOSBC(steering-pool)# ip-address 192.168.10.201
PCOSBC(steering-pool)# start-port 20000
PCOSBC(steering-pool)# end-port 20100

        end-port                                20100

an easy way to verify the number of ports assigned ot realms is issuing the command show mbcd realm

PCOSBC# show mbcd realms
05:55:51-47
                 --- Steering Ports ---  ----------- Bandwidth Usage ----------
Realm             Used   Free  No Ports    Flows Ingrss Egress  IngrssPriority EgressPriority  Total  Insuf BW
External             0    101         0        0     0K     0K         0K         0K              0K         0
Internal             0    101         0        0     0K     0K         0K         0K              0K         0

This command can be used in real time to verify if ports are enough to support current sessions.
