Using the Strom-control (Storm Control) feature in three-layer switching, this feature is based on port-controlled unicast \ Multicast \ Multicast, which can be accurate to 0.01%, but an approximate value. This method is a threshold way, limit the monitoring time per second, more than the set threshold to discard the packa

message is an illegal message, discard, but in some cases the source Mac and the destination MAC address of the data frame is indeed the same out of the interface, In order for the switch to be able to not discard the frames in these special cases need to enable the exchange of Port bridge features, such as the switch is not equipped with a two-layer forwarding
For many enterprise network administrators, switches are naturally the most commonly used equipment. So how much do you know about vswitches? Next we will use an example to discuss the practice of vswitch port configuration and access security protection!
Scenario: There is a CISCO3550 switch in a certain unit. For the sake of network security, the security requirements for some ports are high, that is, on
bandwidth description:
When the Ethernet frame is 64 bytes, the fixed overhead of the 8 byte frame header and the 12 byte frame gap must be considered. Therefore, the packet forwarding rate of A 1-gigabit Ethernet port when forwarding a 64-byte packet is 1.488 Mpps. The 10-in-10 Gigabit Ethernet packet forwarding rate is 148.8 kpps.◆ For
tags. Each 24-port full-gigabit switch enables the port priority. Then, we will observe the results of the 24-port full-gigabit switch processing different priority packets.
The second type is that the tested port is divided into
lower priority are treated differently from those with a lower priority.The test method is to send data frames from three ports to 4th ports at the same time. Each port starts from 30% of the load, and then increases by 10% each time until 100% of each port, causing congestion, view the results of processing data frames of different priorities on the 24-
24-port full-Gigabit Switch forwarding performance and line-end congestion tests. The current 24-port full-Gigabit Switch market is in great competition, some may not know the forwarding Performance Test and line congestion test of 24 full gigabit switches. After reading the following articles, you will become an exper
three major issues, is the first choice for building a "harmonious" Internet cafe network.
The energy saving of RG-S1824GT-E lies in the non-Fan Design and port energy saving design. The RG-S1824GT-E adopts the non-Fan Design of natural heat dissipation mode, compared with the similar full Gigabit Switch products with a fan, its power saving is as high as 40% or more. An Internet cafe with 200 pcs.

I will talk about two tips, one about monitoring switch port traffic and the other about store value.
1. Monitor switch port traffic

SNMP, POP3, and HTTP data streams that simulate UDP ports 161,110 and 80 to ports 4 at the same time.
The priority of the three data packets is the highest in the 24-port full Gigabit Switch, the highest in SNMP, the lowest in POP3, and the lowest in HTTP. The traffic on the three ports starts from 30% of the load and sends data packets to the congestion port. T

Between PC1 and PC2 in different VLANs, by setting the upper layer three switch SwitchB VLAN interface 10 I
