XL-HB14128M HomePNA3.0 Switch User’s Guide
Priority in Upstream
3 levels of service can be provided. With priority value 0 and 1 is regarded as the basic level. Priority value 2 and 3 is
a higher level. Priority value 4, 5, 6, and 7 is the highest level.
Port-Based Priority
Assign each HomePNA port (1 to 14) with a value within 0 to 7. Packet enter high priority port (for example, port with
priority value 6 or 7) will go out faster than packet enter low priority port (as priority value 0 or 1). It takes effect in the
upstream direction.
802.1P
Tagged packet contains the 3-bit (0~7) 802.1P field regarded as priority. The default priority mapping setting is usually
workable. For example, to map 802.1P value to priority 7, to map value 0 to priority 0, and so on. It takes effect in both
downstream and upstream.
IP TOS
The bit7 to bit5 of Type Of Service byte in IP packet is treated as TOS precedence value (0~7). By default,
XL-HB14128M uses the precedence value for priority. Instead, it may adopt the TOS value (bit4 to bit2 of TOS byte)
as priority.
TCP/UDP Port Number
Different TCP or UDP port number usually states for different protocol. You may raise the priority for important
application with specified TCP or UDP port number. In XL-HB14128M, you can assign higher priority for total 8
different TCP/UDP ports.
E1 Static MAC
Port E1 can secure and preserve up to 8 set of predefined MAC address. To bind some servers’ MAC addresses to port
E1 for security reason.
