求教两个端口速率的问题,希望各位同行能帮忙解答一下,谢谢了!
问题一:
一台N7K与ASR1006互联,端口上没有修改速率,业务一直都正常,今天整理网络拓扑的时候,发现这两端的速率不一致,一端是1000M,一端是100M,那这条链路的实际速率应该是100M吧?这会不会存在什么隐患?
在N7K上使用show interface看到端口速率为1000M:
Ethernet10/1 is up
admin state is up, Dedicated Interface
Hardware: 10/100/1000 Ethernet, address: 8478.ac20.fac1 (bia f872.ea42.a584)
Description: TO ASR1006_G1/2/0
Internet Address is 192.168.100.2/30
MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec
reliability 255/255, txload 4/255, rxload 1/255
Encapsulation ARPA, medium is broadcast
full-duplex, 1000 Mb/s
在对端的ASR1006上使用show interface看到端口速率为100M:
GigabitEthernet1/2/0 is up, line protocol is up
Hardware is SPA-2X1GE-V2, address is 4c00.823c.fb60 (bia 4c00.823c.fb60)
Description: TO N7K_E10/1
Internet address is 192.168.100.1/30
MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100 usec,
reliability 255/255, txload 4/255, rxload 40/255
Encapsulation ARPA, loopback not set
Keepalive not supported
Full Duplex, 100Mbps, link type is auto, media type is RJ45
问题二:
N7K上Eth10/43端口,端口上没有修改速率,但在使用show inter status与show inter des命令看到的speed不一致,这是为什么?
N7K上使用show inter status看到Eth10/43端口speed为100:
--------------------------------------------------------------------------------
Port Name Status Vlan Duplex Speed Type
--------------------------------------------------------------------------------
Eth10/43 -- connected 90 full 100 10/100/1000
使用show inter des看到Eth10/43端口speed为1000:
-------------------------------------------------------------------------------
Port Type Speed Description

Eth10/43 eth 1000 --
