clear counters interface command on FabricInterConnect

kashima yoshihito · ‎05-08-2015

after logging in nxos on FabricInterconnect ,

I used "clear counters interface all" command in order to delete all of the packet-infomations

after than I checked whether the infomations has deleted .

I know All packet-infomations have deleted ,

regardless of deleting These Infomations , I found "Last clearing of show interface counters" has not changed "

when i used "show int " command .

As For FC port , I found "last clearing of show interface" counters has changed .

Is this a bug ?

Hi kenny

I checked two UCS

one is FI6248 whose version is 2.2(3a), nxos is 5.2(3)N2(2.23a)

the other is FI6324 which is 3.0(2c), nxos is 5.0(3)N2(3.02c)
