Smart Mode Switch functionality:
1) Traffic entering ports on side A will only show up at same port on side B. Single, Double and
untagged traffic can be sent across. Each incoming port is assigned a different PVID to map the traffic
to Port 9. Ingress ports are configured as unaware hybrid. Port 6 is a trunk port with all frames being
tagged on egress.
2) Management traffic from a designated local port or the modem port will be MAC filtered and sent to
CPU port. Not user traffic at management port. ACL rule to redirect traffic with CPU MAC to port 7
3) 1588 PTP messages only will be filtered and sent to Port 1 which is a high priority fixed latency
modem port. ACL rule to redirect 1588 PTP messages(untagged, tagged, UDP, TCP) to port 1.
4) MAC learning is disabled.

Multilayer Header Compression
When dynamic multilayer header compression is enabled, up to 1.5 Gbps per carrier
capacity (IPv4) can be achieved for small packets without the dependency on traffic
payload. Up to 2048 headers are stored in a database and the Ethernet header is
replaced with a 2 or 4 byte tag. The tag is re-mapped to the correct Ethernet header on
the far end of the link. Statistics are available to show the effectiveness of the Header
Compression Engines. There are two engines used for compressing the streams, one
primarily for L2 portion of the header, and another for the L3-L4 portions of the header.
A higher percentage indicates better compression effectiveness. For a single stream of
IPV4 with UDP the percentage can be as high as 60%.
Custom channel size and T/R Frequency Duplex Spacing
The 24 GHz unlicensed spectrum is typically very clear due to the narrow antenna
beamwidths required. However, if collocated systems on the same path are required,
