Hello all,
Thank you in advance, and understand this has been discussed several times, so need clarification help please.
Need help to correct process/procedure to set ethernet NIC in UCCX VM from 100/Full-Duplex to 1000/Full-Duplex. OS CLI cannot change this.
Problem Symptom:
UCCX prompts occasionally garbled when played out to callers from PSTN.
Additional Information:
Trying to isolate the source of the problem, and eliminating possible causes.
Found the UCCX server publisher been set to 100Mbps, Full Duplex.
The hardware platform is UCS C220-M3, also hosting CUCM and Unity Connection, these VMs are successfully running with their ethernet interfaces at 1000Mbps Full Duplex (auto negotiate).
I understand that garbled voice could also be network related, so am trying to eliminate as many possible causes.
I don't see any errors on the switch ports interfaces for the UCS host.
Troubleshooting:
- have verified the vmnic0 and vmnic1 on the host is both setup to 1000/full
- have tried rebooting, restarting VM
Environment:
- UCS C220 M3
- UCCX v10.6.1-11000-31
- VM is built with v8 image/template
Really appreciate any next steps or references, or if I need to open a TAC case for assistance.

Hi,
You should be able to change the NIC mode by SSH'ing to the CCX virtual machine and using the set network nic eth0 command as shown below:
admin:set network nic eth0 ?
Syntax:
set network nic eth0 param [value]
param mandatory auto, speed, duplex
value mandatory for auto : [en/dis]
for speed : [10/100]
for duplex: [half/full]
NOTE: 1000BASE-T can only be enabled via auto-negotiation

Ok. So I believe you just need to change the NIC type to VMXNET3 and you'll see it as 1Gbps, bit on all my systems it's still showing auto disabled, and so I don't think that's your problem.
The instructions can he found here:
