If I have the UCSE external interface being used for CIMC, can I still use the internal interface ucse2/0 for hypervisor management.  If so, then my config is:
 
interface ucse2/0
 ip address 192.168.5.254 255.255.255.0
 ip nat inside
 ip virtual-reassembly in
 imc ip address 192.168.1.253 255.255.255.0 default-gateway 192.168.1.254
 imc access-port dedicated
 
But if I configure my ESXi vmnic0 to 192.168.5.253, it does not work.  Any suggestions.

Ken,

I ran some tests in my lab.  Your configuration looks correct; however I think your ethernet connections might be the issue.  In my lab the M port on the UCSE server is connected to the switch.  This connection keeps the BMC data separate and bypasses the router so that no cpu cycles are utlized on it for BMC processing.  The default-gateway as you specified as 192.168.1.254 would be a router interface that is also connected to the switch as well.

My interface configuration looks like:

interface GigabitEthernet0/0
ip address 192.168.1.60 255.255.255.0
duplex auto
speed auto
no cdp enable

interface ucse2/0
ip address 192.168.3.1 255.255.255.0
ip nat inside
ip virtual-reassembly in
imc ip address 192.168.1.61 255.255.255.0 default-gateway 192.168.1.60
imc access-port dedicated

Please let me know if the wiring changes fix the issue.  If this configuration doesn't suit your needs, please provide details of what you are trying to do.

Thanks,

Brett

Brett,

Thanks for the info, but what then is your ESXi settings?  My BMC (or CIMC) works just fine, its the ESXi management console I can not get to remotely.

Ken,

Just to clarify. Do you have your ESXi default-gateway set to 192.168.5.254 ?

Manuka,

I tried setting IP address to 192.168.1.252 and the gateway to 192.168.1.254 and it didn't work.
I tried setting IP address to 192.168.5.253 and the gateway to 192.168.5.254 and that also didn't work.
So I am at a loss on how it is supposed to work.

Ken,

I've got vmnic0 set to IP 192.168.3.5.  I've got my VM as 192.168.3.10.  The VM resides with vmnic0.

Ok, I will try this again.

Thanks,

Reboot the router made the ESXi config now work as well.  Everything is back to the old mode.  So I can restart testing tomorrow morning.
