Configuring an UCS-EN140N-M2 in a ISR4451 router

joelm · ‎08-24-2020

I have a UCS-EN140N-M2 in an ISR4451 router (running Cisco IOS XE Software, Version 16.08.01) with this configuration:

router#show platform
Chassis type: ISR4451-X/K9

Type escape sequence to abort.

As you can see, I can successfully ping the CIMC interface from the router and so can any host in the VLAN100 subnet. However, I can't ping it from any host in the VLAN50 subnet.

The instructions in Getting started Guide for UCS E-Series Servers starting on page 42 are incorrect, and I don't see what I'm doing wrong.

Can anyone offer me suggestions on what I have mis-configured?
