Frequently Asked Questions
Q: Which managed switches support Message Rate Limiting?
A: All Sixnet switches support Message Rate Limiting.
Q: What exactly does Message Rate Limiting do?
A: Message rate limiting restricts the amount of Broadcast and Multicast traffic that passes through the switch. It has no effect on other types of communication, such as unicast.
Q: Is message rate limiting adjustable?
A: On all ET, SL, SLX, EK and EF switches, rate limiting is not adjustable; it can only be enabled and disabled on a per-port basis. The rate limits are fixed based on message type and priority. The rates are as follows:
| Background | 10% of link capacity |
| Normal | 20% of link capacity |
| Expedited | 40% of link capacity |
| Urgent | 80% of link capacity |
The EL series supports fully adjustable rate limiting on both ingress and egress. This can be done on a per-port basis.
