Description
Configure the IDS rule session limits for an individual destination or source address or subnet. This protects against network probing attacks and network flooding attacks. This IDS rule can only be assigned to a service set on an MS-MPC.
You can specify limits for specific protocols (ICMP, TCP, and UDP), or specify limits independent of a protocol.
When a session limit is exceeded for a source or destination, packets from the source or to the destination are dropped until the session limit is no longer exceeded.
To specify limits for destination or source subnets rather than
individual addresses, include the aggregation statement
at the [edit services ids rule rule-name term term-name then] hierarchy level.
The remaining statements are explained separately. See CLI Explorer.
