交换机端口流量如何查询？

看哪一个参数呢，老师。 GigabitEthernet1/0/1 Current state: UP Line protocol state: UP IP packet frame type: Ethernet II, hardware address: 083a-382c-ec6c Description: xushulong Bandwidth: 1000000 kbps Loopback is not set Media type is twisted pair Port hardware type is 1000_BASE_T 1000Mbps-speed mode, full-duplex mode Link speed type is autonegotiation, link duplex type is autonegotiation Flow-control is not enabled Maximum frame length: 10240 Allow jumbo frames to pass Broadcast max-ratio: 100% Multicast max-ratio: 100% Unicast max-ratio: 100% PVID: 99 MDI type: Automdix Port link-type: Access Tagged VLANs: None Untagged VLANs: 99 Port priority: 0 Last link flapping: 3 weeks 1 days 23 hours 1 minutes Last clearing of counters: Never Current system time:2013-01-23 23:02:10 Last time when physical state changed to up:2013-01-01 00:00:53 Last time when physical state changed to down:2013-01-01 00:00:13 Peak input rate: 0 bytes/sec, at 2013-01-01 00:00:52 Peak output rate: 2211 bytes/sec, at 2013-01-01 00:06:13 Last 300 seconds input: 0 packets/sec 0 bytes/sec 0% Last 300 seconds output: 3 packets/sec 870 bytes/sec 0% Input (total): 0 packets, 0 bytes 0 unicasts, 0 broadcasts, 0 multicasts, 0 pauses Input (normal): 0 packets, - bytes 0 unicasts, 0 broadcasts, 0 multicasts, 0 pauses Input: 0 input errors, 0 runts, 0 giants, 0 throttles 0 CRC, 0 frame, - overruns, 0 aborts - ignored, - parity errors Output (total): 5114961 packets, 1072015754 bytes 49453 unicasts, 1280940 broadcasts, 3784568 multicasts, 0 pauses Output (normal): 5114961 packets, - bytes 49453 unicasts, 1280940 broadcasts, 3784568 multicasts, 0 pauses Output: 0 output errors, - underruns, - buffer failures 0 aborts, 0 deferred, 0 collisions, 0 late collisions 0 lost carrier, - no carrier

dis counters inbound/outbound interface GE1/0/1

以上命令可看接口带宽使用率

一步步排查网速是在哪个部分开始变慢的
