Rate Control
Note: Most of the SFP transceivers provide vendor information which allows the RocketLinx ES7528 to read it. The user
interface can display vendor name, wave length, and distance of all Comtrol SFP transceiver models. If you see
Unknown info, it may mean that the vendor does not provide their information or that the information of their
transceiver cannot be read.
If the plugged DDM SFP transceiver is not certified by Comtrol, the DDM function is not supported, but the
communication is not disabled.
Rate Control
Rate limiting is a form of flow control used to enforce a strict bandwidth limit at a port.
You can program separate transmit (Egress Rule) and receive (Ingress Rule) rate limits at
each port, and even apply the limit to certain packet types as described below. You can
increment the volume step by 64Kbps in the blank.
Port Status
Description
Port
Port interface number.
Type
100BASE-TX -> Fast Ethernet port. 1000BASE-TX -> gigabit Ethernet port.
Link
Link status. Up -> Link UP. Down -> Link Down.
State
Enable -> State is enabled. Disable -> The port is disable/shutdown.
Speed/Duplex
Current working status of the port.
Flow Control
The state of the flow control.
SFP Vendor
Vendor name of the SFP transceiver that is plugged into the port.
Wavelength
The wave length of the SFP transceiver that is plugged into the port.
Distance
The distance of the SFP transceiver that is plugged into the port.
Temperature
The temperature specific and current detected of DDM SFP transceiver.
Tx Power (dBm)
The specification and current transmit power of DDM SFP transceiver.
Rx Power (dBm)
The specification and current received power of DDM SFP transceiver.
Reload
Click to reload the port status.
Eject/Eject All
Eject the DDM SFP transceiver. You can eject one port or eject all by click-
ing Eject All.
Rate Control
Description
Limit Packet
Type
The packet types all types of packets, broadcast/multicast/unknown
unicast packets, broadcast/multicast packets, and broadcast packets
only.The ingress rate supports all types of packets. The egress rate
supports all types of packets.
Bandwidth
The ports support port ingress and egress rate control. For example,
assume that Port 1 is 10000 Kbps, you can set it's effective egress rate at
2000 Kbps, ingress rate is 1000 Kbps. The switch performs the ingress
rate by packet counter to meet the specified rate.
Ingress
Ingress rate in Kbps, the rate range is from 1000 Kbps to 1000000 Kbps
and zero means no limit. The default value is no-limit.
Egress
Egress rate in Kbps, the rate range is from 1000 Kbps to 1000000 Kbps
and zero means no limit. The default value is no-limit. Egress rate limit-
ing has an effect on all types of packets, including unicast, multicast, and
broadcast packets.
