# Setting a One-Rate Rate-Limit Profile

You can use the rate-limit-profile one-rate command to create a rate-limit profile and enter Rate Limit Profile Configuration mode, from which you can configure attributes for the rate-limit profile. See Table 11.

| Note: The JUNOSe software includes the layer 2 headers in the calculations it uses to enforce the rates that you specify in rate-limit profiles.

Use one of the ip, ipv6, l2tp, or mpls keywords in front of the command to specify the type of rate-limit profile you want to create or modify. If you do not include one of the keywords, the router creates an IP rate-limit profile by default.

For hierarchical rate limits, do not specify the interface type, but add the hierarchical keyword at the end. The color-aware keyword is only supported on hierarchical rate limits.

If you do not include a one-rate or two-rate keyword, the default is a two-rate rate-limit profile. If you enter a rate-limit-profile command with the one-rate keyword and then type exit, the router creates a rate-limit profile with the default values listed in Table 13.

Table 13: One-Rate Rate-Limit-Profile Defaults

Policy Attribute | Default Value
--- | ---
type | one-rate
committed-rate | 0
committed-burst | 8192
excess-burst | 0
committed-action | transmit
conformed-action | transmit
exceeded-action | drop
mask (IP and IPv6 rate-limit profiles) | 255
exp-mask (MPLS rate-limit profiles) | 7

| Note: We recommend that you do not configure a committed or peak burst size smaller than the MTU of the interface. Doing so causes large packets to be dropped even when they are transmitted at a very low rate.

- Issue the ip rate-limit-profile command in Global Configuration mode:
  `
  host1(config)#ip rate-limit-profile tcpFriendly10Mb one-rate
  `

  | Note: Commands that you issue in Rate Limit Profile Configuration mode do not take effect until you exit from that mode.
