 | Option | Description |
 | -------- | ------------ |
-| `maximum` |  The maximum number of unreachability prefixes that the switch can receive from the peer or peer group. This is critical for security to prevent state exhaustion. |
+| `inbound maximum` |  The maximum number of unreachability prefixes that the switch can receive from the peer or peer group. This is critical for security to prevent state exhaustion. |
 | `reestablish-wait` | The time in minutes to wait before establishing the BGP session again with the peer or peer group. You can specify a value between 1 and 65535, or `auto`. The default value is `auto`, which uses standard BGP timers and processing. |
 | `warning-only` | When enabled, the switch only generates a syslog warning if the number of received unreachability prefixes exceeds the limit. |
 | `warning-threshold` | The percentage of the maximum at which a syslog warning is generated. You can specify a value between 1 and 100. The default value is 75.|
