Hi Experts ,
We have server connected to 2 Leaf switches in VPC mode .LEAF101 and LEAF102 ... We found CRC error on LEAF101 eth1/10 interface .So we have replaced the Fiber cable and sfp port ..But now we could see CRC errors on LEAF102 eth1/10 interface (earlier crc was not there in this interface ) .
And also from the Solarwinds graph we could see traffic is now on LEAF102 only and error is also on LEAF102 .There is no traffic on LEAF101 eth1/10 interface and no CRC errors .
On Vpc both interface should serve the traffic right ? do you see any issue on this ?
Hi @Network_Sarovani ,
@Sergiu.Daniluk should be sleeping, so I'll answer on his behalf,.
Probably the easiest way to shut down a port is to simply navigate to the Physical Interface, right-click and Disable it.
Fun Fact When Looking for VPC Interfaces
You can also find the interfaces for a VPC in two other places. Under the VPC Interfaces (expected) AND under PC Interfaces (unexpected, perhaps - BUT ACTUALLY EASIER)
In the picture below, I can find the interface (eth1/47) for a VPC pretty easily so long as I've given the VPC a reasonable name - in the illustration below, the port umber (47) is part of the VPC name.
However, to find the SAME VPC under the VPC Interfaces branch of the tree, I have to go expanding random numbers until I luck on the right number!
And when I DO luck on the correct number, what I see is an exact copy of the same information found in the PC Interfaces branch of the tree!

Yep.
We are facing an communication issue during replication(backup) between 2 servers SERVER-01 and SERVER-02 .
SERVER-01 is a production server and SERVER02 is backup server . May be during the backup the communication fails .
We had CRC errors/input errors on the Switch side . After reseating the Fiber cable and SFP ports , We are not observing any CRC error . But the initial issue reported by server team is till there .
on the switch interface within vpc only one interface has input traffic and on other interface the input rate is 0 . So when we checked the graph in solarwinds ,We observed that during the backup (time 02:15 CET to 02:30 CET) , the receive traffic on eth1/14 LEAF101 switch has 101GB of Bytes received but on LEAF102 it's just 5KB of received Bytes ...
On other side transferred Bytes on LEAF205 eth1/22 interface is 95 MB and transferred Bytes on LEAF206 eth1/22 interface is 107Gb ..?
when the traffic reaches POD-2 why it is not load shared between LEAF205 and LEAF206 ? Is there any issue here or it is how the port-channel or Vpc interfaces should work ???
