Hi All
I'm having trouble finding RCA for around 100 plus server blades (7 IBM Enclosures) got network fluctuation causing some application stop on these servers.
Topology:
Server-1 blades(14 no.'s)-->IBM Switch embedded (L2)-->Port X/Y of N5K(each port X/Y is a member of Port-channel XX)
Server-2 blades(14 no.'s)--> same as above-->Port X2/Y2 of same N5K
-----list goes on to Server 7 Connecting to same N5K (2 no. in Redundant fashion)
Suspecting issue:
At same time, a team member was doing troubleshooting on a Port-channel which is not related to these enclosures Port-channels but on the common switch A. All enclosures Port-channels and troubleshooted Port-channels have same Vlan running in deep down to Servers.
Now my question is
1. if some-one doing shut, no shut of port-channel, deleting and then reapplying VPC for that PO, Creating new PO and VPC will effect another PO's and VPC's in such extent that around 7 PO's in that switch goes down and become member less of their respective ports.
2. How likely it is if some config changes in a neighboring VPC,PO's can cause malfunctioning of other PO's running in same switch.
PFA the toptology.
