SVSI (AMX / HARMAN Networked AV)
SVSI is AMX/HARMAN's proprietary Networked AV platform for AV-over-IP distribution, not one universal wire protocol. Treat the port table below as the native local-platform baseline for current AMX Networked AV planning, then add branch-specific streaming, audio-interoperability, directory, security, and management requirements for the exact submitted system.
Scope: N2600, N3300 and N-Command profiles; separately scoped legacy KVM and ancillary services

Infrastructure Requirements
- Managed Ethernet switching as a baseline, not an optional enhancement
- explicit IGMP snooping/querying for multicast-oriented branches, with Immediate Leave / Fast Leave behavior checked against the exact switch platform
- separate VLAN planning for video, audio, and control on converged networks
- enough per-port and uplink bandwidth for the chosen stream family including querier/uplink behavior
- security-policy alignment if using 802.1X, directory services, and TLS features
- a service-by-service firewall schedule covering native SVSI control/media, web/secure shell/file-transfer, HControl, N-Command, AES67, Dante AV, serial/IR/KVM, transport-stream, HTTP Live, and branch-specific streaming modes where used
- careful series-to-series compatibility planning because SVSI is a platform umbrella, not one universal bitstream

Gotchas & IT Notes
- ⚠Select the model and enabled feature; the combined table is not a blanket allowlist.
- ⚠N2600 Dante AV-A includes randomized TCP allocations beyond port 60000. N-Command WebView ranges depend on the unit count.
- ⚠Secure control/serial services use the base port plus 100 where enabled.
- ⚠Match multicast, bandwidth and switch configuration to the encoder/decoder family; the checked multicast defaults are planning context, not a blanket service allowance.
