3. Troubleshooting Functional Failures During Operation

(f) Checking the filters and QoS configuration information

Only certain packets might have been discarded by filtering, or packets might have been discarded

by bandwidth monitoring, drop control, or the QoS control shaper.

On the Switch and the relay device between the DNS server and the DHCP server, make sure that

the setting conditions for filters and QoS control in the configuration are correct, and that

bandwidth monitoring, drop control, or the shaper is used appropriately in the system

configuration. For details about the procedure, see 3.25.1 Checking the filters and QoS

configuration information.

In addition, if DHCP snooping is used, packets might have been discarded by a terminal filter.

Check whether the setting conditions for DHCP snooping in the configuration are correct. For

details about the procedure, see 3.27 DHCP snooping problems.

(g) Checking the Layer 2 network

If you do not find any incorrect settings or a failure in the steps (a) to (f), there might be a problem

with the Layer 2 network. Check the Layer 2 network according to 3.6 Layer 2 network

communication failures.
