Rate Limiting
Congestion Control
The switch can set the maximum upload or download data transfer rate for any
port. It can control traffic storms by setting a maximum threshold for broadcast
traffic or multicast traffic. It can also set bounding thresholds for broadcast and
multicast storms which can be used to automatically trigger rate limits or to shut
down a port.
Congestion Control includes following options:
◆
Rate Limiting
– Sets the input and output rate limits for a port.
◆
Storm Control
– Sets the traffic storm threshold for each interface.
◆
Automatic Traffic Control
which can be used to trigger configured rate limits or to shut down a port.
Use the Traffic > Rate Limit page to apply rate limiting to ingress or egress ports.
This function allows the network manager to control the maximum rate for traffic
received or transmitted on an interface. Rate limiting is configured on interfaces at
the edge of a network to limit traffic into or out of the network. Packets that exceed
the acceptable amount of traffic are dropped.
Rate limiting can be applied to individual ports. When an interface is configured
with this feature, the traffic rate will be monitored by the hardware to verify
conformity. Non-conforming traffic is dropped, conforming traffic is forwarded
without any changes.
Parameters
These parameters are displayed:
◆
Interface – Displays a list of ports or trunks.
◆
Type – Indicates the port type. (1000BASE-T, 100BASE SFP, or 1000BASE SFP)
◆
Status – Enables or disables the rate limit. (Default: Disabled)
◆
Rate – Sets the rate limit level. (Range: 64 - 1,000,000 kbits per second)
– Sets thresholds for broadcast and multicast storms
