Hiper 510 當機與系統日志

[ean_ycchu]

Hi 華網您好 :
於幾日前,網路突然不通.
至現場重啟Hiper 510及中華電數據機後, 才可正常連接.

後來在系統日誌中,看到hiper 510 好像只有記錄出當機後的狀況.
當時的log 如下,
2106-02-05 06:28:54 Call Terminated @clearSession:5
2106-02-05 06:28:59 PPPoE Up 00:30:88:1d:c8:f9
2106-02-05 06:28:59 Call Connected @_netiNetworkStateChanged:6244, on Line 1, on Channel 0
2106-02-05 06:28:59 Session Up PPPOE
(可能是此時當機了)
2013-08-14 10:16:03 Incoming Call @_netiNetworkStateChanged:6187, on Line 1, on Channel 0
2013-08-14 10:16:03 Call Connected @_netiNetworkStateChanged:6244, on Line 1, on Channel 0
2013-08-14 10:16:03 Assigned to port @answerIncomingCall:8012
2013-08-14 10:16:03 Session Up AF202
2013-08-14 10:17:52 Attack tcp attack,tcppps = 5735,tcpLimit = 3000
2013-08-14 10:17:52 Attack 10.0.0.10 is offline
2013-08-14 10:17:53 Attack tcp attack,tcppps = 25875,tcpLimit = 3000

當機前的log,看來並無保留下來.
1. 請問這樣是否正常?

2. 有一台nettv3 被設定成DMZ,可是後來看到log 一直出現這個訊息, 請問是否正常? (此台裝置於internet 是能夠正常access)

Hi:
若發生網路異常,請試試看是否可以單機聯通路由設備,確認是哪一個環節的問題.
Log 狀況無異常, 設於DMZ 的此台設備超出session 大小限制. 表示此台設備的連接數超出你設定的大小, 超出連線的部分自然被丟棄.

另外510建議使用Client 數量不要超過20個, 最好為20個client 以下.
