S9703 switch interconnect with VAMPA board problem

Publication Date:  2014-02-24 Views:  310 Downloads:  1
Issue Description
At the beginning of Core network implementation we start to prepare internal routing between devices. We found that there is no internal connectivity between ACU and S9703 chassis – traffic (icmp, arp) cannot pass.
Alarm Information
No alarms
Handling Process
Lab lests confirmed this problem
Root Cause
During troubleshooting procedure we tried:
- Use ether-trunk between ACU and chassis – no result
- Use single XGigabit interface in trunk or access mode – no result
- Software upgrade of chassis and ACU also has no effect.
When we move ACU board from S9703 to S7706 we found that board is works fine! So, it mean problem in S973 chassis.
Suggestions
This Case can show you, that S9703 chassis may have SW bug when operating with ACU board.
