My packet capture captured less than I wanted or failed.
The packet capture screen’s File Size sets a maximum size limit for the total combined size of all the
capture files on the NXC, including any existing capture files and any new capture files you generate. If
you have existing capture files you may need to set this size larger or delete existing capture files.
The NXC stops the capture and generates the capture file when either the capture files reach the File
Size or the time period specified in the Duration field expires.
My earlier packet capture files are missing.
New capture files overwrite existing files of the same name. Change the File Suffix field’s setting to avoid
this.
The screens of the NXC Web Configurator are not displaying properly.
Clear cache and cookies from your web browser, and try to access the Web Configurator again.
36.1.2 Wireless
This section provides troubleshooting for wireless devices connected to the NXC.
APs cannot be managed by the NXC.
• There may be a configuration mismatch between the AP and the NXC. This could be the result of a
number of things, such as incorrect VLAN topology, incorrect AP profiles, incorrect security settings
between the AP, and the NXC.
See Section 6.11 on page 86 for how to check if the AP’s runtime management VLAN ID setting
matches the NXC’s management VLAN ID setting for the AP.
See Section 6.11.1 on page 90 for how to check if the AP’s configuration is in conflict with the NXC’s
settings for the AP.
• The wireless client’s MAC address may be on the MAC filtering list. See Section 19.3.3 on page 275 for
details on managing the NXC MAC Filter.
• Your AP needs to support CAPWAP managed AP mode in order to be managed by the NXC. See the
NWA/WAC Series User’s Guide.
