9.3.6 Configuring Port Traffic Rate Limiting
Purpose
To limit the incoming rate of traffic entering the Matrix E1 on a per port/priority basis. The
allowable range for the rate limiting is as follows:
• For 10/100 ports: 195000 to 100,000,000 bits per second (Bps)
• 1000Base-SX/LX: 195000 to 1,000,000,000 bits per second (Bps)
• 10/100/1000: 195000 to 1,000,000,000 bits per second (Bps)
The inbound rate limit is configured for a given port and list of priorities. The list of priorities can
include one, some, or all of the eight 802.1p priority levels. The rate of all traffic entering the port
with the priorities configured to that port is not allowed to exceed the programmed limit. If the rate
exceeds the programmed limit, frames are dropped until the rate falls below the limit.
Commands
The commands to configure traffic rate limiting are listed below and described in the associated
section.
• show port ratelimit (Section 9.3.6.1)
• set port ratelimit (Section 9.3.6.2)
