Hello, at work they recently connected an Isilon server to a Nexus 3172. I am connected with a QSFP broken into 3 interfaces to 3 nodes on the Isilon. I can log into the Isilon and see all interfaces are up with an MTU configured of 9000 but I can not ping above 1472. My config below has 9216 but I had it set at 9000 and it did not work. Am I missing anything in my configuration or is there not enough output shown below?
-----------
policy-map type network-qos jumbo
class type network-qos class-default
mtu 9216
system qos
service-policy type network-qos jumbo
-----------
interface Ethernet1/50/1
switchport access vlan 131
speed 10000
interface Ethernet1/50/2
switchport access vlan 131
interface Ethernet1/50/3
switchport access vlan 131
