Re: AES-CCMP TSC replay was detected

Hi Jackal,

From:

http://www.cisco.com/en/US/docs/wireless/access_point/12.3_8_JA/configuration/guide/s38err.html

Error Message: DOT11-4-CCMP_REPLAY: "AES-CCMP TSC replay was detected on packet (TSC

0x%11x received from &e)."

Explanation: AES-CCMP TSC replay was indicated on a frame. A replay of the AES-CCMP TSC in a received packet almost indicates an active attack.

Recommended Action: None.

HTH,

Re: AES-CCMP TSC replay was detected

Hi J

thanks for reply, yes i have checked cisco site as well, your msg basically was same to Cisco. i feel something is not right, coz i noticed wlan connection affected and some more if no action taken, then what does this msg stand for ? if just information only why Cisco need to advertise the logs on the device ? it maybe client software problem or cisco device problem ? ... hmn.....

anyway, thanks for ur update.

thanks.

Jackal
