A.2.14.3 UTP Port 3 Rate Limiting
The 1000EAS provides per port ingress and egress rate limiting. For bandwidth settings, IRL or ingress rate
limit refers to limiting any packets coming into the converter, while ERL or egress rate limit refers to limiting packets
leaving the converter. When rate limiting is applied, ERL will use pause commands (802.3X) when the desired rate
limit is exceeded, while any IRL setting will cause packet to be dropped when the limit is exceeded. This is an
important point when doing the rate limit settings. It is preferable to set ERL at each port for the path that requires
limiting so that flow control can help connected devices cope with the limiting. If IRL is employed, a connected
device which has its packets dropped without flow control, will continue to send packets at its full rate. Also, since
the packets are dropped, the application layer can only deal with the packet loss by timing out.
The ingress rate setting menu. Select rate from 70K to 250M or unlimited.
The same setting rates can be applied to the egress direction.
