Count mode
Egress rate limiting count mode. This parameter is used to control which bytes in the transmitted
frames are counted for egress rate limiting as follows:
• frame — The egress rate limiting is done based on frame count [fps] as opposed to the byte
count [kbps] of the packet.
• layer 1 — Preamble (8bytes) + Frame’s DA to CRC + IFG (inter frame gap, 12 bytes)
• layer 2 — Frame’s DA to CRC
• layer 3 — Frame’s DA to CRC - 18 - 4 (if the frame is tagged)
Only one tag is counted even if the frame contains more than one tag. A frame is considered tagged
if the egress frame going out onto the wire is tagged.
Rate limit
Egress data rate shaping. When Rate = 0 egress rate limiting is
disabled
.
Note
The
Count mode
parameter is used to control which bytes in the transmitted frames are
counted for egress rate limiting.
If the egress shaping is controlled by
frame rate
, the desired frame rate can vary from 7.6k to
1.488M frames per second. Valid values are between 7632 and 1488000.
If the egress shaping is controlled by
bit rate
, the desired rate can vary from 64 kbps to 1 Gbps in
the following increments:
• Desired rate between 64 kbps and 1 Mbps in increments of 64 kbps
• Desired rate between 1 Mbps to 100 Mbps in increments of 1 Mbps
• Desired rate between 100 Mbps to 1 Gbps in increments of 10 Mbps
Therefore, the valid values are:
• 64, 128, 192, 256, 320, 384,..., 960,
• 1000, 2000, 3000, 4000, ..., 100000,
• 110000, 120000, 130000, ..., 1000000.
Frame overhead [B]
This parameter is used to adjust the number of bytes that need to be added to a frame’s IFG (inter
frame gap) on a per frame basis. This is to compensate for a protocol mismatch between the
sending and the receiving stations. For example, if the receiving station were to add more encap-
sulations to the frame for the nodes further downstream, this per frame adjustment would help reduce
the congestion in the receiving station.
