CA Spectrum NCM task can do external communication accessing the device for capturing device communication using SNMP/TFTP, Telnet/FTP and SSH/SCP methods. With CA Spectrum 9.2.3 the Telnet/FTP communication method may fail due to large banner pages and/or Enable Password configuration with privileged user on the device.
The problem is seen using NCM Global Sync Task, bulked tasks and also for a single NCM task to a single device.
A CA Spectrum 9.2.3 debug patch D476 has been created to address this problem. Please open an issue with CA Support to obtain this patch.
