TRILL/3/TRILL_AUTHENTICATION_FAILURE
Message
TRILL/3/TRILL_AUTHENTICATION_FAILURE: The authentication password of received PDU is different from local configuration. (trillSysInstance=[trillSysInstance], trillCircIndex=[trillCircIndex], trillCircIfIndex=[trillCircIfIndex], trillPduFragment=[trillPduFragment], ifIndex=[ifIndex], IfName=[IfName])
Description
The device received a PDU carrying an authentication password that was different from the local one.
Parameters
Parameter Name | Parameter Meaning |
---|---|
trillSysInstance |
TRILL process ID |
trillCircIndex |
TRILL interface index |
trillCircIfIndex |
Interface index obtained from the interface management module |
trillPduFragment |
64-byte PDU fragment |
ifIndex |
Interface index defined by the interface management module |
IfName |
Interface name |
Possible Causes
TRILL authentication was configured for the local interface or process. The authentication mode configured on the remote device was the same as that configured on the local device, but the authentication password configured on the remote device was different from that configured on the local device.
Procedure
- Search the trap for the TRILL process ID, convert the decimal
value of the if-index field into a hexadecimal value based
on the TRILL packet format, and identify the PDU type and the system
ID of the source switch (device that sent the PDU) in the pdu-fragment field.
- If the PDU is a Hello packet, go to Step 2.
- If the PDU is an LSP or SNP, go to Step 4.
Table 92-1 Methods of identifying system IDs and TRILL PDU typesIdentifying the PDU Type
Identifying the System ID
Hello: The fifth byte in the pdu-fragment field is 0f, 10, or 11.
The six consecutive bytes from the tenth byte of the pdu-fragment field is the system ID.
LSP: The fifth byte in the pdu-fragment field is 12 or 14.
The six consecutive bytes from the thirteenth byte of the pdu-fragment field is the system ID.
SNP: The fifth byte in the pdu-fragment field is 18, 19, 1A, or 1B.
The six consecutive bytes from the eleventh byte of the pdu-fragment field is the system ID.
- Run the display trill peer command on the source switch to check the interface that sent the PDU and run the display this command in the interface view to check whether the configured
authentication password is the same as that configured on the destination switch.
If the two passwords are the same, go to Step 6.
If the two passwords are different, go to Step 3.
- Run the trill authentication-mode command in the interface view of the source switch to change the authentication password to the one configured on the
destination switch and then check whether the trap is cleared.
If the trap is cleared, go to Step 7.
If the trap persists, go to Step 6.
- Run the display current-configuration configuration trill command on the source switch to check whether the configured authentication password is the same
as that configured on the destination switch.
If the two passwords are the same, go to Step 6.
If the two authentication passwords are different, go to Step 5.
- Run the area-authentication-mode command in the TRILL view of the source switch to change the authentication password to the one configured on the
destination switch and then check whether the trap is cleared.
If the trap is cleared, go to Step 7.
If the trap persists, go to Step 6.
- Collect log information and configuration information, and then contact technical support personnel.
- End.
