I cannot get the firmware uploaded using the commands.
The Web Configurator is the recommended method for uploading firmware. You only need to use
the command line interface if you need to recover the firmware. See the CLI Reference Guide for
how to determine if you need to recover the firmware and how to recover it.
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.
35.1.2 Wireless
This section provides troubleshooting for wireless devices connected the NXC.
Wireless clients cannot connect to an AP.
• 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, and so on.
See Section 5.11 on page 71 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 5.11.1 on page 72 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 18.3.3 on page
227 for details on managing the NXC MAC Filter.
