Message: 
----------
I am having the similar issue with the Nexus 7000 switches, Nexus 5000
switches and ACE 4710 load balancers. I have no problem with other 300
Cisco devices and routers.

I am using Linux version 3.8.13-55.1.5.el6uek.x86_64 (Red Hat 4.4.7-3) and
rsyslogd 5.8.10. The firewall is turned off and selinux is set to
Permissive. I didn't set up any filter. The tcpdump shows the log message
from the Nexus 7000 (172.30.187.202) has been received by the server
syslogvm (172.30.187.78) which in on the same vlan. They can ping each
other so there is no routing issue. However, Rsyslog server won't write the
log messages to the files. I've been struggling for a week and still
couldn't figure out why. Please help. Thank you very much.

Tcpdump output is showing below.
