Initial solution was addressed for CA Spectrum R10.3.0 - when then upgraded to R10.3.1.
This is documented at section: "OneClick Known Anomalies" from https://docops.ca.com/ca-spectrum/10-3-0/en/release-information/known-anomalies
Related first TecDoc for this is: https://knowledge.broadcom.com/external/article?articleId=125304
The workaround via edit to the CA Spectrum Oneclick-server configuration files (XML file update) is working for CA Spectrum R10.3.1 too.
However in R10.3.1 the issue was not fully resolved - and full solution is listed as:
Symptom : Information Tab doesn't display any information with Spectrum 10.3.1. The Information Tab stays empty blank for ever for Cisco ASR routers which is having large IPRouteTable.
Resolution: In View-devicedetails-config.xml there is check to display entry from which table based on ipRouteDest list attribute (0x100b1) . Since we are waiting to finish reading the attribute 0x100b1.
The fix is now available within patches:
10.03.01.PTF_10.3.110 for CA Spectrum R10.3.1 + BMP_101 base install.
