    Configuring a Default Rate Limit

    The “default rate limit” is a limit applied to sessions that do not match APE rules. This option is disabled by default. You can enable it by specifying a rate limit for such sessions.

    Note: If you have enabled per user rate limiting (also called per subscriber rate limiting), the default rate limit is applied per user. If not, the default rate limit is a maximum allocation for all sessions that do not match APE rules.

    To assign a default rate limit for sessions that do not match APE rules:

    1. Log into the CLI as admin and enter su - to switch to root.
    2. Use the following command to show the current value:

      [root@defaulthost admin]# scio const get sc_ape_default_rate_limit
      scio: sc_ape_default_rate_limit = 0xffffffff

      The default is 4,294,967,295 bps (0xffffffff in hexadecimal; 4,096 Mbps or .5 Gbps), which effectively turns off rate limiting for sessions that do not match APE rules.

    3. If you want to set a rate limit for sessions that do not match APE rules, use the corresponding set command. The following example sets a limit of .25 Gbps:

      [root@defaulthost admin]# scio const set sc_ape_default_rate_limit 2147483648
      scio: setting sc_ape_default_rate_limit to 0x80000000
