下表显示每个字段的说明。
表 2. show interface 字段
字段
|
说明
|
Interface ID
|
接口 ID。
|
“interface_name ”
|
逻辑接口名称。如果不配置名称,则在硬件行之后会出现以下消息:
Available but not configured via nameif
|
is state
|
管理状态,如下所示:
|
Line protocol is state
|
线路状态,如下所示:
-
up - 工作电缆插入网络接口。
-
down - 电缆不正确或未插入接口连接器。
|
VLAN identifier
|
对于子接口,是 VLAN ID。
|
Hardware
|
接口类型、最大带宽、延迟、复用和速度。在链路断开时,复用和速度显示配置的值。当链路连通时,这些字段显示配置的值,并在括号中包含实际设置。
|
Media-type
|
(并非始终显示)显示接口介质类型,例如 RJ-45 或 SFP。
|
message area
|
在某些情况下可能显示消息。请参阅以下示例:
|
MAC address
|
接口 MAC 地址。
|
Site Specific MAC address
|
对于集群技术, 显示正在使用的站点特定 MAC 地址。
|
MTU
|
此接口上允许的最大数据包大小(以字节表示)。如果没有设置接口名称,此字段显示“MTU not set”(未设置 MTU)。
|
IP address
|
接口 IP 地址,静态或从 DHCP 服务器接收。
|
Subnet mask
|
IP 地址的子网掩码。
|
Packets input
|
此接口上接收的数据包数。
|
Bytes
|
此接口上接收的字节数。
|
No buffer
|
块分配的失败数。
|
Received:
|
|
Broadcasts
|
接收的广播数。
|
Input errors
|
输入错误总数,包括如下所示的类型。其他与输入有关的错误也可能导致输入错误计数增加,并且一些数据报可能有多个错误;因此,这个总数可能超过以下类型列出的错误数。
|
Runts
|
由于小于最小数据包大小(64 字节)而丢弃的数据包数。超短帧通常是由冲突引起的。也可能是由接线不良和电子干扰引起的。
|
Giants
|
由于超出最大数据包大小而丢弃的数据包数。例如,大于 1518 字节的所有以太网数据包均被视为超长帧。
|
CRC
|
循环冗余检查错误数。当站发送帧时,会将 CRC 附加到帧尾。此 CRC 是使用算法基于帧中的数据生成的。如果在源和目的地之间更改了帧,系统会注意到 CRC 不匹配。CRC 数量过大通常是冲突或站传输错误数据引起的。
|
Frame
|
帧错误数。错误的帧包含长度不正确或帧校验和错误的数据包。此错误通常是冲突或以太网设备故障引起的。
|
Overrun
|
因输入速度超出接口处理数据的能力而导致接口无法将接收的数据传递至硬件缓冲区的次数。
|
Ignored
|
不使用此字段。值始终为 0。
|
Abort
|
不使用此字段。值始终为 0。
|
L2 decode drops
|
因未配置名称或接收具有无效 VLAN ID 的帧而丢弃的数据包。在冗余接口配置中的备用接口上,此计数器的数值可能因该接口没有配置名称而增加。
|
Packets output
|
在此接口上发送的数据包数。
|
Bytes
|
在此接口上发送的字节数。
|
Underruns
|
发射器运行速度比接口处理速度更快的次数
|
Output Errors
|
因超过已配置的最大冲突数而未传输的帧数。在网络流量巨大时,此计数器的数值只会增加。
|
Collisions
|
由于以太网冲突(单一和多个冲突)而重新传输的消息数。这通常发生在过度扩展的 LAN(以太网或收发器电缆太长、站之间超过两个中继器或层叠的多端口收发器太多)上。输出数据包仅对发生冲突的数据包计数一次。
|
Interface resets
|
接口已重置的次数。如果接口在三秒内无法传输,系统会重置接口以重启传输。在此时间间隔内,保持连接状态。接口环回或关闭时,也会出现接口重置。
|
Babbles
|
未使用。(“babble”意味着发射器在接口上的时间大于传输最大帧所花费的时间。)
|
Late collisions
|
因冲突发生在正常冲突时间范围之外而未传输的帧数。延迟冲突是在传输数据包中延迟检测到的冲突。通常,这些不应该发生。当两台以太网主机同时尝试通信时,它们应在数据包的早期阶段发生冲突且双方都退出,或者第二台主机应看到第一台正在通信和等待。
如果遇到延迟冲突,设备将迅速行动并尝试在以太网上发送数据包,而 威胁防御 设备已部分完成发送数据包。 威胁防御 设备不重新发送数据包,因为它可能已释放保留数据包第一部分的缓冲区。这不是真正的问题,因为网络协议设计为通过重新发送数据包来解决冲突。但是,延迟冲突指示您的网络中存在问题。常见问题是运行着大量重复的网络和以太网络,超出了指定范围。
|
Deferred
|
在传输之前由于链路上的活动而延迟的帧数。
|
input reset drops
|
当发生重置时,计算 RX 环中丢弃的数据包数。
|
output reset drops
|
当发生重置时,计算 RX 环中丢弃的数据包数。
|
Rate limit drops
|
将接口配置为非千兆位速度而尝试传输超过 10 Mbps 或 100 Mbps(具体取决于配置)时丢弃的数据包数。
|
Lost carrier
|
在传输期间载波信号丢失的次数。
|
No carrier
|
未使用。
|
Input queue (curr/max packets):
|
输入队列中数据包的当前数和最大数。
|
Hardware
|
硬件队列中的数据包数。
|
Software
|
软件队列中的数据包数。对千兆位以太网接口不可用。
|
Output queue (curr/max packets):
|
输出队列中数据包的当前数和最大数。
|
Hardware
|
硬件队列中的数据包数。
|
Software
|
软件队列中的数据包数。
|
input queue (blocks free curr/low)
|
当前/低条目指示接口的接收(输入)描述符环上当前可用和始终可用的最低插槽数。这些数值由主 CPU 更新,因此最低(直到接口统计信息清除或设备重新加载)水印不是十分准确。
|
output queue (blocks free curr/low)
|
当前/低条目指示接口的接收传输(输出)描述符环上当前可用和始终可用的最低插槽数。这些数值由主 CPU 更新,因此最低(直到接口统计信息清除或设备重新加载)水印不是十分准确。
|
Traffic Statistics:
|
接收、传输或丢弃的数据包数。
|
Packets input
|
The number of packets received and the number of bytes.
|
Packets output
|
传输的数据包数和字节数。
|
Packets dropped
|
丢弃的数据包数。通常,当加速安全路径 (ASP) 上丢弃数据包(例如,如果数据包由于访问列表拒绝而被丢弃)时,此计数器数值会增加。
有关接口上潜在丢弃的原因,请参阅 show asp drop 命令。
|
1 minute input rate
|
在过去一分钟内接收的数据包数(包/秒和字节/秒)。
|
1 minute output rate
|
在过去一分钟内传输的数据包数(包/秒和字节/秒)。
|
1 minute drop rate
|
在过去一分钟内丢弃的数据包数(包/秒)。
|
5 minute input rate
|
在过去 5 分钟内接收的数据包数(包/秒和字节/秒)。
|
5 minute output rate
|
在过去 5 分钟内传输的数据包数(包/秒和字节/秒)。
|
5 minute drop rate
|
在过去 5 分钟内丢弃的数据包数(包/秒)。
|
Redundancy Information:
|
对冗余接口,显示成员的物理接口。主用接口在接口 ID 后有“(Active)”。
如果您尚未指定成员,您会看到以下输出:
Members unassigned
|
Last switchover
|
对冗余接口,显示上次主用接口故障切换到备用接口的时间。
|

注
|
show interface detail 命令结果中的输入和输出速率可能与 管理中心 用户界面的接口模块中显示的输入和输出流量速率不同。
接口模块根据 Snort 性能监控的值显示流量速率。Snort 性能监控和接口统计信息的采样间隔不同。这种采样间隔的差异会导致 管理中心 用户界面和 show interface detail 命令结果中的吞吐量值不同。

以下是 show interface detail 命令的输出示例。以下示例展示所有接口的详细接口统计信息,包括内部接口(如果针对您的平台存在)和非对称路由统计信息(如果已启用):

说明
|
Demux drops
|
(仅在内部数据接口上)因 威胁防御 设备无法多路复用来自其他接口的数据包而丢弃的数据包数。
|
内部数据接口 |
数据平面(系统支持 diagnostic-cli)上的接口是 Internal-Data0/0 和 Internal-Data0/1。
其中每个接口都有一个缓冲区。其中一个设备线程从缓冲区读取数据,并将数据包移动到 RX 环中。例如,在 4120 设备中,环总数为 23(从 00 到 22),其中 RX 环 16 和 17 为 OSPF 保留。同样,根据设备型号,某些环会保留给故障转移和
CCL 数据包。
这些环是数据包堆栈,可确保来自同一数据流的数据包顺序相同;具有相同 5 元组(基于源/目的 IP)的数据包将始终位于同一 RX 环上。

Control Point Interface States:
|
|
Interface number
|
用于调试的编号,指示此接口创建的顺序,从 0 开始。
|
Interface config status
|
管理状态,如下所示:
-
active - 该接口没有关闭。
-
not active - 接口被有意关闭。
|
Interface state
|
接口的实际状态。在大多数情况下,此状态与上述配置状态匹配。如果配置高可用性,则可能不匹配,因为 威胁防御 设备会根据需要打开或关闭接口。
|
Asymmetrical Routing Statistics:
|
|
Received X1 packets
|
在此接口上接收的 ASR 数据包数。
|
Transmitted X2 packets
|
在此接口上发送的 ASR 数据包数。
|
Dropped X3 packets
|
在此接口上丢弃的 ASR 数据包数。当尝试转发数据包时,如果接口关闭,则可能丢弃数据包。
