Network Analysis Module NAM easy monitoring and switching network

Most network administrators use port mirroring, data generation technology, or passive networks to configure network detectors. Although these solutions can work barely, they will have negative effects, affect network performance and response speed, and perform tedious and slow operations. To address these problems, Cisco has released its network analysis module NAM. NAM is designed for Cisco switches of the Catalyst 5000, 6000, and 6500 series. It i

host-b between the Doom game data traffic must pass through all 7 bridges. If I didn't tell you not to choose the root bridge randomly, then let me point out how bad the facts are for you. Assume that the Cat-1 is a software bridge made by an earlier Cisco MGS or AGS Router (a 2-tier forwarding capability is approximately equal to 10,000 packets per second), and the remaining six devices are Catalyst 5500 or 6000 switches (2-tier forwarding capabilit

Causes, prevention and troubleshooting of broadcast storms

I. CausesA broadcast storm means that too many broadcast packets consume a large amount of network bandwidth and normal data packets cannot be transmitted over the network. Generally, a broadcast packet causes multiple responses, each response results in multiple responses. Just like a snowball, all the bandwidth of the network is exhausted. This phenomenon is usually caused by network loops, faulty NICs, viruses, etc.Ii. Prevention (take Cisco Catalyst

specific version of The VTP configuration. the value of the Configuration Modification number starts from 0. Each time it is modified, it is increased by 1 until it reaches 4294967295. Then, it is cyclically set to 0 and increased again. each VTP device records its own VTP Configuration Modification number. The VTP packet contains the VTP Configuration Modification Number of the sender. this information is used to determine whether the received information is updated later than the current info

QoS policies for lan ip Phones

Traditional Ethernet frame header, of which 802.1p occupies three places. 802.1p extends the 802.1d Protocol. A maximum of eight priority levels can be provided with a three-bit priority. 802.1Q uses VI (VLAN Identifier, virtual network Identifier) bits to identify which virtual network the transmitted frame belongs. A total of 12 VI bits are supported. The maximum number of virtual networks supported is no more than 4096. 2. qoS in the queue management LAN is used to check when a communication
