Host DoS Configuration describes how to configure Host DoS on an S- K- and 7100-Series device. Host DoS configuration commands are entered in global configuration command mode.
Step | Task | Command(s) |
---|---|---|
1 | Enable host DoS globally for this device. Threats must be specifically enabled for mitigation to occur for that threat as specified in the following step. | hostdos enable |
2 | Enable a mitigation type, and optionally set the rate at which events will be acted upon. | hostdos {mitigation-type | enable | icmp-maxlength icmp-maxlength} [rate count [per-second | per-minute | per-hour | per-day]] [nolog] |
3 | Optionally, set a logging event-rate for one or all DoS attack types, specifying the rate per specified time period. | hostdos mitigation-type event-rate count {per-seconds | per-minutes | per-hours | per-days} |
4 | Optionally, disable logging for the specified DoS attack types. | hostdos mitigation-type nolog |
5 | Optionally, specify an ICMP maximum packet size for icmpsize mitigation. | hostdos icmpsize maxlength length |
Managing TACACS+ describes how to display Host DoS configuration state and counters on an S- K- and 7100-Series device.
Step | Task | Command(s) |
---|---|---|
1 | Display configuration state for one or all Host DoS attack mitigation types. | show hostdos [mitigation-type] |
2 | Display statistic counters for one or all Host DoS attack mitigation types. | show hostdos [mitigation-type] [stats] |
