I have a question regarding Isolating SMs in PMP Option 2 - Forward SM destined packets upstream.
When this is enabled how is this accomplished? What are the side effects of enabling this? (the goa is to have all traffic pass from SM to AP to switch then back if needed for CALEA compliance.
SMs in the sector can be prevented from directly communicating with each other.
If SM1 and SM2 are both on AP1, then will be unable to communicate directly with one another. This can be useful to eliminate chatter and broadcast traffic on an AP.
Enable Option 2 - Forward SM destined packets upstream. This not only prevents multicast/broadcast and unicast SM-to-SM communication but also sends the packets, which otherwise may have been handled SM to SM, through the Ethernet port of the AP.
I hope this should help you.
