The information contained herein is subject to change without notice.32 QA iSPI tuning • Beware of bugs in RTT-MIB and CBQoS in Cisco IOS when enabling QA SPI. Some IOSs reboot when SNMP is polled in these MIBs • Disable CBQoS and create filters for IP SLA probes if you know you have lots of implementations of these configurations. Otherwise it can create a big load on the system • Use CNA. Create node groups base on CNA. We integrate with other system to set CNA SLA for different devices automatically. It helps the NOC to prioritize issues if lots of problems happen at the same time • We also integrate with other systems to add CNAs to show which services this node delivers • Or use SNMP location for grouping TDC background Network topology HP solution Integrations Tips and tricks
