Wireshark session displaying empty field names for wireless packets
Hi,
We are using iTest 4.0.3 for automating a testcase which involves sniffing wireless packets. The wireshark session in iTest is not displaing some fields in the "show details <packet_no>" command. The same field is displaying correctly in the tshark output.
For example a snip from the "show details <packet_no>" output in wireshark session
wlan_mgt.tag.interpretation |
| Vendor Specific: WME <----- No Field displayed
wlan_mgt.tag.number | 221
Same packet snippet from tshark output
Tag interpretation: Unknown + Name: tb4-root1 #Clients: 0
Vendor Specific: WME <---- Field name is correctly displayed
Tag Number: 221 (Vendor Specific)
Tag length: 24

I am attaching both wireshark and tshark output in this post. Can anyone tell me why this is happening ?
Hi,
According to my understanding i think Vendor Specific: WME and Vendor Specific: Aironet CCX version = 5 are a kind of headers and under that the field names and values are mentioned in details.
I hope this information might help you.
Thanks
Yes it is a header but why there is no field name?
Hi,
Are you able to see those fields in Wireshark GUI correctly. If yes could you please attach your .pcap file.
