Multimedia Traffic Control with IP Multicast (IGMP) v2 NG

IGMP, after being re-architected, is referred to as IGMP v2 NG, the next generation of IGMP version 2. IGMP V2 NG is based on the existing working Multicast Listener Discovery (MLD) code base and an event-driven architecture which enable easy enhancement and maintenance of the code. IGMP V2 NG uses Multicast Traffic Manager (MTM) to program hardware filters and MAC address.

The syslog hostname configuration is system-wide, not per syslog server.
