Cisco switch QoS Speed limit configuration steps:1. Enable Global QoS2. Set the ACL matching traffic3. Set a class-map to match the ACL set in the second step4, set a Policy-map match Class-map, and then define a series of policies here, limit the bandwidth bitwise (BIT) for the calculation, burst in bytes (byte) calculation5, apply the POLICY-MAP to the correspo

When we want to perform permission rating management on a Cisco router or switch, it is often necessary to assign different levels of users a command that exceeds the default settings, such as show run, which is the most basic troubleshooting command.However, the command cannot be executed when your user level is at 0-14.

Disable forwarding of a specific MAC address on a cisco SwitchIt is really annoying to see other illegal DHCP in the LAN. In addition to the dhcp snooping method, you can also directly disable the mac address! The MAC address of machine A is 00-01-02-03-04-05, which is connected to port F0/3 of Switch B, port F0/3 is in VLAN3. Currently, forwarding of A is blocked on port B. You can set the following accord

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 st
