MD5 failed cisco 6509

22:31:44.950 UTC: %TCP-6-BADAUTH: No MD5 digest from 10.10.10.1(646) to 10.10.10.2 (29167) (RST) tableid - 0

sometimes we received this error in the log

After troubleshoot  we found the hash is the same in both sides,.so our other option
check if error is related to same interfaces this will point to the module .

sh int gi4/0/0 and sh int gi4/0/1 we found there is not traffic in that interfaces

so the next step if check if there was any fail in the ASIC or inidication of any fault in the module

we can do sh diag module  number (in this case 4)

so the action recomended is

procedure to reboot a module in cisco

#hw-module module number reset

other
config t
config)# no power enable module number

test>>> sh diag module number
sh module
