fex switches bounce to other nexus

hi all,

got two nexus 7000 connected via vpc to eachother but only one switch (core 1) contains all the configs for the 10 fex switches we have attached to them, all the fex switches have port channels to each switch

when they bounce to the other switch (core 2), they lose connection as the configs for them on core 1, so i have to bounce them back to core 1, i do this via doing on core 2

conf t

int po(whatever)

shut

then it goes back to core 1

is there any reason why it bounces them and whats the best remedy for this not happening again

thanks,

rob

whats the difference between static pinned and port channel, as i have said each fex is linked back to core 1 and core 2 via pos on both nexus's plus the nexus's are connected to eachother via vpc

actually we got this

Single Homed Host and Active-Active FEX (VPC) Design

and our nexus versions on each are 12.x

so do our nexus 7ks support this or not

can you draw topology ?

Just looked on both cores and there running v6.2 so this is why it's not working

Thanks so much MHM
