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(configure)# media-manager 

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 

PCOSBC(steering-pool)# realm-id External

PCOSBC(steering-pool)# done

steering-pool

 ip-address 192.168.10.201

 start-port 20000

 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.
