There are times where more than one VM is running on an Appliance and they can not ping each other. When this happens you will need to enable promiscuous mode
To enable promiscuous mode first open a terminal on the appliance and log in as root. If you do not have the root password, please let me know and I can send it to you. After you in as root run
and you should see that eth0 has a flag of BMRU. Next run
ip link set eth0 promisc on
Now run the netstat -i again and your flag should now be BMPRU.
Flag details are as follows:
B flag is for broadcast
M flag is for multicast
P flag is for promisc mode
R is for running
U is for up
When the DR is over run
ip link set eth0 promisc off
To turn off promiscuous mode. This setting should not be permit and a reboot will clear the flag. You should not have to do this on all Appliances. This issue is from a limitation of the NIC and Switch.
To make it per, add ip link set eth0 promisc on above the Xeit 0 line in rc.local
