CSCus73066 | M2/F2 linecard reset due to EOBC heartbeat failure |
The M2, F2, and NAM line cards, as listed in the Products Affected section, might be reset by the Supervisor due to the Ethernet Out of Band Channel (EOBC) heartbeat that is missed by the line card. This EOBC heartbeat communication, which consists of diagnostic and system management signals, is essential for the line card to function properly.
In scenarios where customers run NX OS versions earlier than Version 6.2 (14), there are communication issues between the Supervisor and the M2, F2, and NAM line cards where heartbeats go missing between the full duplex Gigabit link. This EOBC heartbeat communication, which consists of diagnostic and system management signals, is essential for the M2, F2, and NAM line cards to function properly.
This system error code shows the "EOBC heartbeat failure" message.
