we have two 6506 switches with Sup2 in different locations, connected with a fibre. Recently we have been receiving the following alert on both of them:
%C6KERRDETECT-SP-2-LPBKFAIL: The in-band loopback test between switch processor and route processor failed, count:10
SP: SP-RP Ping Test: CPU util(5secs): SP=5% RP=16%, Traffic=0%
SP: SP-RP Ping Test: netint_thr_active, Tx_Rate, Rx_Rate, bus_stall
Cisco are sayng that the Sup may need to be replaced. Surelly the same error should not happen on two devices at the same time?
Any ideas anyone?
