hi

dùng chương trình error decoder:

1. %SYS-3-NOELEMENT: [chars]:Ran out of buffer elements for enqueue
The process was unable to enqueue data because it ran out of buffer elements.

Recommended Action: Copy the error message exactly as it appears on the console or in the system log. Issue the show tech-support command to gather data that may help identify the nature of the error. If you cannot determine the nature of the error from the error message text or from the show tech-support command output, contact your Cisco technical support representative, and provide the representative with the information you have gathered.

hi

nếu chuyển về xác thực từ local thì lỗi trên còn xuất hiện không?

sửa lại như sau:

aaa authentication login default group tacacs+ local

hoặc

aaa authentication login default local

thử xem và vui lòng cho biết kết quả.

[thabeo]

Router của tôi không thể login vào được dù đã cắm dây console. Khi cắm dây console, rồi bật router lên khi bấm enter thì báo là authentication failed. Các bạn có biêt cách nào sửa được lỗi này ko, và vào lại được router của tội

Xin cám ơn rất nhiều

[thabeo]

Thưa anh Minh, sau khi đã làm theo cách của anh chi dận Router vẫn báo lỗi:

[trung tam kn]

lổi này là do cấu hình phần AAA quên chỉ ra phần local. Trong phương thức xác thực chỉ có tacacs hoặc radius nên router sẽ không cho phép truy cập vào router.

Giải pháp là telnet vào routers, hoặc thử crack password.

[lj]

Hi thabeo !
Mình mạo muội có ý kiến .
Có vẻ như khi chạy router thiếu Ram, bạn thử nâng cấp ram hoặc giảm ram cấp cho router khi khởi động xem,sau đó reload.
Rgds.

[lj]

Hi thabeo !
Có thể khi bạn cấu hình AAA phần authentication cho line console xác thực bằng line password, nhưng lại quên cấu hình hoặc xóa mất dòng lệnh "password xxx" trong cấu hình line console. bạn làm theo cách của "trung tam kn" xem sao.

Rgds.
