Since the upgrade to 21.2 communications with TL1 devices is effectively stopped. When running sniffer traces with tcp dump or wireshark we are not seeing any traffic on the tl1 ports. We are also not seeing any traffic from the TL1 to the network.
Secure Corba changes in 21.2.1 and above caused communication failures.
Release : 21.2
Component : Spectrum Applications
This has been resolved by patch 21.2.1_D08 for 21.2.1 and in Spectrum_21.02.02.PTF_21.2.201 for Spectrum 21.2.2. This fix will be included in NetOps Spectrum release 21.2.6.
