Configuring Virtual Chassis Virtual Chassis Overview
OmniSwitch AOS Release 7 Switch Management Guide March 2015 page 12-13
Note: If more than one Virtual Chassis is part of the same EMP out-of-band management network
then each Virtual Chassis MUST have a unique chassis-group ID. Otherwise the RCD protocol
cannot differentiate between the two Virtual Chassis and will not operate correctly.
Split Chassis Detection - OS10K CMMs
Directly connecting the EMP ports of the CMMs on the Slave and Master switches is not a recommended
method for detecting a split chassis scenario. Using directly connected CMM EMP ports could result in a
scenario where the Primary CMM on one switch is directly connected to the Secondary CMM on the other
switch if a local CMM takeover occured on one of the switches. Since the RCD protocol is only active on
the Primary CMM, this would result in a loss of RCD communication.
