ESXi Network troubleshooting issue

[kmarty009]

We are trying to troubleshoot a VMKernel issue via NFS and believe that traffic is getting routed out to the core switch. However, we cannot verify this because I have no tools in ESXi 4.1 to run tracert, traceroute, tracepath etc. Am I missing something here....? Where are the tracert tools on ESXi? I cannot image that VMware cut those out?

Describe your problem, maybe we can help without using tools.

I have an IBM Blade Center with 2 1GB Switches which I use for the ESXi Management Network. I have 2 other switches that are 10GB with 10GB cards. I am connecting via NFS for my Datastores. When pinging at 1500 MTU with vmkping it is working. When I ping with -m 9000 it works on some and fails on other addresses that worked at 1500. Long story short... we believe the ESXi mgmt network is routing the traffic at 1500 to our core switch and at 9000 it is not. We need to use a tracert just verify where are traffic is going. But ESXi does not have any of these tools from to verify it. All I want is to use vmkping and watch where the traffic is going.

Why don't you configure th ESXi vSwitches to use Jumbo Frames? By default they are not set to this MTU size. The default is 1500.

I did configure vswitch1 to MTU 9000 however vswtich0 is 1500 which is only used for ESXi Management.
