Table 8. FID+SA Look-Up in the VLAN Mode
Advanced VLAN features are also supported in KS8995MA, such as “VLAN ingress filtering” and “discard non PVID” defined
in Register 18 bit 6 and bit 5. These features can be controlled on a port basis.
Rate Limit Support
KS8995MA supports hardware rate limiting on “receive” and “transmit” independently on a per port basis. It also supports rate
limiting in a priority or non-priority environment. The rate limit starts from 0Kbps and goes up to the line rate in steps of 32Kbps.
The KS8995MA uses one second as an interval. At the beginning of each interval, the counter is cleared to zero, and the rate
limit mechanism starts to count the number of bytes during this interval.
For receive, if the number of bytes exceeds the programmed limit, the switch will stop receiving packets on the port until the
“one second” interval expires. There is an option provided for flow control to prevent packet loss. If the rate limit is programmed
greater than or equal to 128Kbps and the byte counter is 8K bytes below the limit, the flow control will be triggered. If the rate
limit is programmed lower than 128Kbps and the byte counter is 2K bytes below the limit, the flow control will be triggered.
For transmit, if the number of bytes exceeds the programmed limit, the switch will stop transmitting packets on the port until
the “one second” interval expires.
If priority is enabled, the KS8995MA can support different rate controls for both high priority and low priority packets. This can
be programmed through Registers 21–27.
