Cisco switch port broadcast storm settings

Cisco switch port broadcast storm settings are more practical. When a port receives a large number of broadcast, unicast, Or multicast packets, a broadcast storm occurs. Forwarding these packets will slow down the network or cause timeout. Using broadcast storm control on ports can effectively avoid network paralysis caused by hardware damage or link failure. By default, broadcast, multicast, and unicast storm control is disabled. 1. To enable storm control, follow these steps. The specific descriptions of the commands in the Code are listed below www.2cto.com: level. Specifies the upper bandwidth limit of the blocked port. When broadcast, multicast, or unicast transmission accounts for the proportion of bandwidth (percentage), the port will block transmission. Value Range: 0.00 ~ 100.00. If you set the value to 100%, no transmission is restricted. If you set the value to 0%, all broadcasts, multicast, and unicast on the port will be blocked. Level-low. Specifies the bandwidth limit of the enabled port. This value should be less than or equal to the lower limit. When the proportion of bandwidth occupied by broadcast, multicast, or unicast transmission is lower than this value, the port resumes forwarding. Value Range: 0.00 ~ 100.00. Bps. Bps can be expressed as bit/s. Specifies the upper limit of the port blocking transmission rate. When broadcast, multicast, or unicast transmission reaches several bps per second, the port will be blocked. Value Range: 0.0 ~ 10 000 000 000.0. Bps-low. Specifies the lower transmission rate limit enabled on the port. This value should be less than or equal to the lower limit. When broadcast, multicast, or unicast transmission is less than several bps per second, the port will resume transmission. Value Range: 0.0 ~ 10 000 000 000.0. If the value is large, k, m, or g headers can be used for representation. Pps. Specifies the upper limit of the port blocking forwarding rate. When the broadcast, multicast, or unicast transmission rate reaches several packets per second (pps), the port will be blocked. Value Range: 0.0 ~ 10 000 000 000.0. Pps-low. Specifies the lower transmission rate limit enabled on the port. The value must be less than or equal to the lower limit. When the forwarding rate of broadcast, multicast, or unicast packets is lower than several packets per second (pps), the port will resume transmission. Value Range: 0.0 ~ 10 000 000 000.0. If the value is large, k, m, or g headers can be used for representation. Example: When the bandwidth usage is 30%, the broadcast package is blocked (generally only one upper limit is entered, and the lower limit is kept by default). Example: When the bandwidth usage is 30%, when int f0/1storm-control broadcast level 30.00 reaches 60 broadcast packets per second, blocking starts. If the number of broadcast packets is lower than 30, stop blocking (this must have the upper and lower limits) int f0/1storm-control broadcast level pps 60 30 Note that the blocking method can only be set to one.
