Hi Team
in a few days I will renovate 2 legacy 6500 in VSS mode with a pair of c9500.
They will be a collapse core in a very legacy envirotment and our customer asks me to enable jumbo frame in these cores. I'm afraid if I enable globally system mtu 9000, it could impact downlinks connections with legacy accesss switches, routers or firewall connect directly with this core.
is it a recomendation to go for it? or should i tell to my customer keep with the default MTU.
thanks,
Jhon
