Error Code 98321

This indicates that the communication between the Web LCT and the NE is
abnormal. Please check whether the communication network and parameter
settings between the PC and the NE are correct.

Handling Process

Modify the submask of NE 9-8 as 255.255.255.0, and fault is removed.

Root Cause

1. This is a local login fault, so there is no business with the Microwave link itself.

2. Since it is a fault of communication, so communication parameters
should be firstly check and the following information is got:

NE 9-8   NE IP: 10.109.1.8 Submask: 255.255.0.0
NE 9-9   NE IP: 10.109.1.9 Submask: 255.255.255.0
Laptop IP:10.109.1.125 Submask: 255.255.255.0

3. Check the IP routing table, and pick out the two key items as follow:

4. As we know, when Weblct on the laptop logins into the NE 9-8, the
laptop sends out the packet to the NE 9-8, and the NE 9-8 sends back a
reply packet according to the routing foward table, and right now as
shown above in the route table ,there are two available pieces of
routing, 10.109.0.0/16 and 10.109.1.0/24, and the corresponding
interface are NMS port (Etherent1) and Microwave link(Serial2), based on
the longest match principle, 10.109.1.0/24 is the final option, and the
reply packet is forwarded to Serial2 but not Ethernet1, in another
word, the laptop can not receive the reply packets, and the Weblct login
fails.

Suggestions

DCN parameters should be uniformly planned and carefully configured.
