You only need to route it once to switch it multiple times without needing to query it every time. 　　 Six CEF CEF-Based Multi-layer switch cisco pxpress forwarding (three tables) FIB table (forwarding information database) Joining

The following are the modules supported by vswitch 4500: WS-F4531-Cisco Catalyst 4500 NetFlow service daughter WS-X4148-FE-LX-MT-Cisco Catalyst 4500 Fast Ethernet Switching Module, 48 Port 100BASE-LX10 Single-Mode Optical Fiber SMF) MT-RJ) WS-X4148-FX-MT-Cisco Catalyst 4500 Fast Ethernet Switching Module, 48 Port 100BASE-FX multimode fiber MMF) MT-RJ) WS-X4148-RJ-Cisco Catalyst 4500 10/100 module, 48 Port RJ-45) WS-X4148-RJ21-Cisco Catalyst 4500 10/10

module, protecting users' investment. This series of features mainly include: www.2cto.com port density is high. Supports up to 384 10/100 BaseTx adaptive Ethernet ports, 192 100 BaseFX optical fiber fast Ethernet ports, and 130 Gigabit Ethernet ports (GBIC slots ). Fast. The C6500 switching backplane can be extended to 256 Gbps, and the multi-layer switching speed can be extended to 150 Mpps. The C6000 switching backboard bandwidth is 32 Gbps, and the multi-layer switching rate is 30 Mpps. Sup

In terms of the comprehensive performance of Cisco SUP720, how can we understand Cisco SUP720? You will find many methods on the network. The following article compares the performance in three aspects, hope to help the majority of fans. Compared with SUP720, The sup720-3BXL is mainly different from the PFC used by the two. The SUP720-BXL uses PFC3BXL, while the SUP720 uses PFCA, And the SUP720 can be upgraded to a SUP720-3BXL by replacing the PFC. Cisco SUP720 Scalability:◆ The number of Route

solution is as follows. Figure 3 system protection Overview Now, if the server in the Shanghai IDC center is under heavy DDoS attacks, the protection process is as follows. 1,Attack DetectionIn the event of a DDoS attack, the attack traffic monitoring device deployed inside the core network and at the exit of the IDC center sends the Netflow data collected in real time to the security management platform, after judging whether a DDoS attack has occ

connected using Ethernet Channel Technology (Fast EtherChannel, FEC or Gigabit EtherChannel, GEC), logically achieving a port rate of 16 Gbps, you can also implement port aggregation across modules. Multi-layer switching: multi-layer switching modules of the C6000 series can be used for line-rate IP, IPX, and IP-multicast routing. Good Fault Tolerance: C6000 series with redundant super engine, redundant Load Balancing power supply, redundant fan, redundant system clock, redundant uplink connect

If you allow them, check the CAM table again and then send data;Several parts of TCAM:V (patterns): mode M (mask): determines which content to check;R (result): permit or denyCentral Exchange is a previous technology.
