The quota in the RADIUS VSA Credit-Control-Quota uses this fixed format:
Alc-Credit-Control-Quota = ‟<volume-quota>|<time-quota>|<category name>”
volume-quota is specified in bytes (B), in kilobytes (K or KB), in megabytes (M or MB), in gigabytes (G or GB)
time-quota is specified in seconds (s), in minutes (m), in hours (h), in days (d) or a combination (5m30s). A lower unity may never exceed the higher unity: 5m60s is not allowed and should be specified as 6m.
Both volume and time quota should be specified in the attribute but only one credit type (volume or time) is applied per category. The credit-type of a category is configured in the category-map CLI context.
For example, use Alc-Credit-Control-Quota = ‟0|1h30m|cat1” to grant time quota and Alc-Credit-Control-Quota = ‟1G|0|cat2” to grant volume quota.
