Configure Mroute Stream Limit on an Extreme Integrated Application Hosting Port
Note
This procedure only applies to 5720-24MXW, 5720-48MXW, 7520 Series, and 7720 Series.
About this task
Perform this procedure to limit the number of multicast streams to protect a Central Processing Unit (CPU) from multicast data packet bursts generated by malicious applications, such as viruses that cause the CPU to reach 100 percent utilization, or that prevent the CPU from processing protocol packets or management requests. If more than a certain number of multicast streams ingress to a CPU through a port during a sampling interval, the port shuts down until you take appropriate action.
Procedure
- In the navigation pane, expand .
- Select the Extreme Integrated Application Hosting (IAH) port you want to configure.
- Select the Mroute Stream Limit tab.
- Select StreamLimitEnable.
- Configure other fields as required.
- Select Apply.
