13.1.3. Layer-3 Check
If some network segments cannot be used for L3 forwarding, and no problems are found in the L2 check, it can
be conducted:
Step 1 show ip route Check the content of the route table, the
correctness of the route table, and whether
the configured static route and the
OSPF/RIP route have been learnt and the
selection of routes is correct.
Step 2 show interface <ifname> Check whether the related interfaces are
correctly “upped”.
Step 3 show ip route cache Check the correctness of the bottom layer
host route table.
13.1.4. Service Check

13.2. Unstable Service due to Wrong Making of Network
Cables
Basic Information
Name of case Unstable service due to wrong making of network
cables
Product name 3P@C 4450E
Module type and version DS-4TXB
Software version None
Since the implementing party lacks sufficient knowledge of making network cables, assuming that the linear
ordering of the two ends is the same, the actual service cannot be stably run for a long time after being
commissioned. For the physical problem location of this kind, the engineers should be careful enough and
improve their understanding of the Ethernet auto-negotiation and basic principles of communication.
13.2.1. Common Causes
Mismatched working modes of the interconnected ports between both parties
Problem of network adapter
Problem of network
Problem of port module
