(1) Runts: discarded packets that are smaller than the mediums minimum packet size.
( Receive Byte Count < 64 and NOT CRC Error
or Receive Byte Count < 64 and Tag Packet and NOT CRC Error,
無論是否有vlan tag,數(shù)據(jù)段小于64字節(jié),而且沒有CRC校驗(yàn)錯(cuò)誤的幀。)
(2) Giants: discarded packets that are larger than the mediums maximum packet size.
( Receive Byte Count > 1518 and NOT CRC Error
or Receive Byte Count > 1522 and Tag Packet and NOT CRC Error,
沒有vlan tag,數(shù)據(jù)段大于1518字節(jié),小于最大幀長度,而且沒有CRC校驗(yàn)錯(cuò)誤的幀,和有vlan tag,數(shù)據(jù)段大于1522字節(jié),小于最大幀長度,而且沒有CRC校驗(yàn)錯(cuò)誤的幀。)
(3) Throttles: discarded packets that are incomplete frames.
( 交換機(jī)察覺緩存或CPU過載,關(guān)閉接口接收器的情形稱為 throttle,是cisco路由器上的一個(gè)概念,我們的交換機(jī)目前不具備這個(gè)功能,一般應(yīng)該顯示為不支持。)
(4) CRC: discarded packets with checksum error.
( Receive Packet CRC error,幀長度在正常范圍(不帶tag,長度在64到1518之間,或帶tag,長度在64到1522之間),而且CRC校驗(yàn)錯(cuò),如果支持此項(xiàng),則不支持奇偶校驗(yàn)錯(cuò)誤項(xiàng)。)
(5) Frame: discarded packets with frame pad/sequence/alignment error, out of frame etc.
( 不是整數(shù)字節(jié),而是多1~7bit,因此不對齊,或亂序或空幀,而且CRC校驗(yàn)錯(cuò)誤,但是不計(jì)入CRC錯(cuò)誤。)
(6) Overrun: the receiver hardware is unable to hand received data to a hardware buffer because the input rate exceeds the receivers ability to handle the data.
( 由于接口輸入速率超過接受方處理能力,導(dǎo)致丟包,由于我們的交換機(jī)一般是線速轉(zhuǎn)發(fā),這項(xiàng)一般應(yīng)該為0,只有部分交換機(jī)對上傳CPU或三層線速轉(zhuǎn)發(fā)的幀有接口帶寬限制,或是通過ACL實(shí)現(xiàn)的帶寬限制,因此被丟棄的幀,計(jì)入此項(xiàng)。)
(7) Aborts: Input abnormal frames that are discarded.
( 除其他錯(cuò)誤之外,產(chǎn)品認(rèn)為有必要統(tǒng)計(jì)的錯(cuò)誤,例如前導(dǎo)碼異常的幀,計(jì)入此項(xiàng)。)
(8) Ignored: packets that are discarded because the interface hardware does not have enough internal buffers.
( Packet ignored,由于接口內(nèi)部buffer滿,丟棄的幀,與由于主系統(tǒng)緩存空間缺乏,導(dǎo)致的丟棄幀不同。線速轉(zhuǎn)發(fā)的幀,在多接口滿帶寬輸入,單接口輸出等情況下,由于輸出接口的帶寬不足,數(shù)據(jù)幀將內(nèi)部緩存占滿,導(dǎo)致從接口輸入的幀在進(jìn)入內(nèi)部緩存之前被丟棄,以及進(jìn)入內(nèi)部緩存的幀超時(shí)無法輸出,計(jì)入此項(xiàng),上傳到CPU的幀,由于CPU處理能力限制,toCPU的緩存滿,導(dǎo)致被丟棄,也計(jì)入此項(xiàng)。)
(9) Parity: Frames with parity error.
( Receive Packet parity error,如果支持此項(xiàng),則不支持 CRC 錯(cuò)誤項(xiàng)。)
[20] 接口的物理層輸出總值統(tǒng)計(jì) 顯示物理層輸入的報(bào)文數(shù)/字節(jié)數(shù)/廣播和多播/PAUSE幀
總的統(tǒng)計(jì)值只包括正常幀、異常幀和PAUSE幀。
Pauses: Flow control pauses including Xon and Xoff.
[21] 接口的物理層輸出正常幀統(tǒng)計(jì) 顯示物理層輸入的報(bào)文數(shù)/字節(jié)數(shù)/廣播和多播/PAUSE幀
總的統(tǒng)計(jì)值只包括正常數(shù)據(jù)幀和正常PAUSE幀。
[22] 接口的物理層輸出錯(cuò)誤統(tǒng)計(jì) 輸入丟棄數(shù)/輸入錯(cuò)誤數(shù),output errors等于各種重要錯(cuò)誤信息的總和。不同的產(chǎn)品可以根據(jù)具體情況增加其它參數(shù),或減少不能實(shí)現(xiàn)的參數(shù)。
(1) Underruns: There are no data in the output queue.
( Transmit under run,與 Overrun相反,輸出接口的緩存從輸出隊(duì)列中取以太網(wǎng)幀時(shí),沒有幀,是一種非常少見的硬件異常。有的交換機(jī)就沒有單獨(dú)的接口輸出緩存,與接口輸出隊(duì)列是同一塊緩存。)
(2) Buffer failures: Hardware does not have enough internal buffers.
( 內(nèi)部緩存滿,如果輸出隊(duì)列滿,輸出的以太網(wǎng)幀將在內(nèi)部緩存中暫時(shí)存儲,由于內(nèi)部緩存滿,導(dǎo)致幀丟棄。由于交換機(jī)對線速轉(zhuǎn)發(fā)的數(shù)據(jù)幀發(fā)生的這種異常,認(rèn)為只是到達(dá)內(nèi)部緩存而沒有到達(dá)出接口,是個(gè)輸入幀,因此計(jì)入 Input Ignored Error,只有從CPU發(fā)出的幀,由于內(nèi)部緩存滿,導(dǎo)致幀丟棄,計(jì)入此項(xiàng)。)
(3) Aborts: Output abnormal frames that are discarded.
( 在半雙工模式下,由于沖突檢測,延遲發(fā)送超過15次的幀,被丟棄,計(jì)入此項(xiàng)。除其他錯(cuò)誤之外,產(chǎn)品認(rèn)為有必要統(tǒng)計(jì)的錯(cuò)誤,例如添加前導(dǎo)碼異常的幀,也計(jì)入此項(xiàng))
(4) Deferred: The packets could not be sent out for collision under half-duplex mode.
( 半雙工模式下,由于檢測到載波正在被聲明,當(dāng)時(shí)沒有發(fā)出的包,延時(shí)一次,計(jì)數(shù)加一。)
(5) Collisions: Statistic of collision detection under half-duplex mode.
( 半雙工模式下,在以太網(wǎng)幀數(shù)據(jù)部分的前64字節(jié)進(jìn)入線路前,由于檢測到?jīng)_突,當(dāng)時(shí)沒有發(fā)出的包。)
(6) Late collisions: Statistic of collision with GE port sending packets less than 512 bytes and 10/100M port less than 64 bytes.
( 半雙工模式下,在以太網(wǎng)幀數(shù)據(jù)部分的前64字節(jié)進(jìn)入線路后,由于檢測到?jīng)_突,當(dāng)時(shí)沒有發(fā)出的包。)
(7) Lost carrier: Statistic of losing the carrier.
( 載波丟失,一般適用于串行WAN接口,發(fā)送過程中,每丟失一個(gè)載波,此計(jì)數(shù)加一,對于交換機(jī),通常是由于線路中斷造成。)
(8) No carrier: Statistic of no carrier.
( 無載波,一般適用于串行WAN接口,當(dāng)試圖發(fā)送幀時(shí),如果沒有載波出現(xiàn) ,此計(jì)數(shù)加一,對于交換機(jī),通常是由于線路中斷造成。)
