IronClad Rate Limiting
Foundry’s IronClad rate limiting enables you to control the amount of bandwidth specific traffic uses on specific
interfaces, by limiting the amount of data the interface receives or forwards for traffic. You can configure the
following types of rate limiting:
• Fixed Rate Limiting – Enforces a strict bandwidth limit. The device forwards traffic that is within the limit but
drops all traffic that exceeds the limit.
• Adaptive Rate Limiting – Enforces a flexible bandwidth limit that allows for bursts above the limit. You can
configure Adaptive Rate Limiting to forward, modify the IP precedence of and forward, or drop traffic based on
whether the traffic is within the limit or exceeds the limit.
NOTE: If you want to use ARP rate limiting, see “Rate Limiting ARP Packets” on page 15-30.
Rate limiting support differs depending on the Foundry product. Table 14.1 lists the Foundry products on which
rate limiting is supported and the specific rate limiting support on each product.
