Trying to determine the reason for slow server backups on servers connected to a WS-X4548-GB-RJ45 module which has 6 groups of eight ports which share 1Gb bandwidth with associated ASICs & buffers. Don't see excessive pauses or dropped packets however reviewed Document:
Troubleshooting Switch Port and Interface Problems; Document ID: 12027
The document has the following statement:
If the frames received on any group exceeds the bandwidth of 1 Gbps, the device starts to drop the frames.
These drops are not obvious as they are dropped at the internal ASIC rather than the actual interfaces. This
can lead to slow throughput of packets across the device.
So the packet drops at the ASIC level are not obvious and I assume from the document that those drops will not appear on the interface counters.
I checked 'show platform hardware interface all' and did not see those counters
I'm looking for a command which will display the counter of the packets dropped at the ASIC level.
