Configuring the Egress Port Rate Limiting

6.6 Egress Port Rate Limiting

The SBx3112 supports egress port rate limiting on both the CUSTOMER and NETWORK directions.
The major steps and commands used to implement egress port rate metering are as follows:
Create a set of egress limiter names with a RATE and BURSTSIZE.
•
Assign each limiter to a interface/interface range.
•
Table 6-11 lists the increment value and burst size support when configuring the interfaces.
TABLE 6-11
Value
Egress rate limiting increment value (kbps)
Egress rate limiting minimum burst size (KBytes)
Egress rate limiting maximum burst size (KBytes)
On the GE24POE and GE24SFP, the actual limited rate could be off by as much as 72K if the total
Note:
specified rate limit is less than or equal to 293M. The actual limited rate could be off as much as 288K
if the total specified rate is more than 293M.
On the XE4, the actual limited rate could be off by as much as 192K if the total specified rate limit is
Note:
less than or equal to 785M. The actual limited rate could be off as much as 2.1M if the total specified
rate is more than 785M.
