TAILIEUCHUNG - Chapter 8 – Network Troubleshooting

Establishing a network performance baseline requires collecting key performance data from the ports and devices that are essential to network Gather symptoms - Troubleshooting begins with the process of gathering and documenting symptoms from the network, end systems, and users. Stage 2 Isolate the problem - The problem is not truly isolated until a single problem, or a set of related problems, is identified. Stage 3 Correct the problem - Having isolated and identified the cause of the problem, the network administrator works to correct the problem by implementing, testing, and documenting a solution | Chapter 8 -Network Troubleshooting nillllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllir BfKHKHOfl NETWORKING KflDEMY CCNA Exploration CISCO 1 III1IIIII III III II IIIIII111III III III Illi III 111II11IIIIIIIII ------------------BfKHKHOfl NETWORKING ACADEMY DOCUMENTING YOUR NETWORK Học viện mạng Bach Khoa - Website 2 Network Configuration Table Documenting Your Network F Device Name Medel Interface Name MAC Address IP Address Subnet ip Routing Protocd s Mask R1 Cisco 2611XM fa 0 0 0007 . 24 EIGRP10 faQ 1 0007 . 24 EIGRP10 30 OSPF sữ Ũ 1 Not Connected R2 Cisco 2611XM taữ Đ 0007 . 24 EIGRP 10 r- Switch Name.
