Resolution

Note - While there could be multiple other factors that could lead to an ICX being stuck in synchronizing state, this article explains one particular scenario among those scenarios.

On reviewing the configuration of the ICX, it was found that the "snmp-server" configuration was disabled on the ICX as shown below -

no snmp-server  

Therefore, we re-enabled SNMP on the ICX using the following command -

#conf t

#snmp-server

After enabling it, the ICX came up as operational on R1.
