CCIE RS Lab details: Spanning Tree Protocol

In the early days of network development, transparent bridges were an important role that had to be mentioned. It is much smarter than a hub that only amplifies and broadcasts signals. It will quietly record the source MAC address and port number of the data frame sent to it. The next time the packet that encounters the destination MAC address is sent from the port number in the record, unless the destination MAC address is not recorded, or the destination MAC address itself is a multicast addre

CCIE Lab syllabus:Smart second generation—spanning tree protocol

Cisco quickly introduced the improved PVST+ protocol and became the default spanning tree protocol for switch products. The improved PVST+ protocol runs on VLAN 1 as the normal STP protocol, running the PVST protocol on other VLANs. The PVST+ protocol can communicate with STP/RSTP. The spanning tree state on VLAN 1 is calculated according to the STP protocol. On other VLANs, the common switch only forwards the PVST BPDUs as multicast packets according to the VLAN number. However, this does not a

CCIE lab Knowledge Point: Introduction to NetFlow

NetFlow is a toolkit released by Cisco for analyzing network packet information. Different schemes are customized according to different needs. Typically, it analyzes the source address and destination address of network data, analyzes various applications of traffic, or Statistics on the load of each port on the router. Statistics can be performed on the following parameters: addr, dstaddr, port, dstport, protocol, ToS, input interface, output interface, nexthop, masked, Packet count, byte coun
