Overview
rx drop
***FEX queuing disabled on fex 133. Reload the fex to enable queuing.<======
For any new FEXs brought online after an ISSU, queuing is enabled by default.
The queue limit is enabled by default for all FEXs, regardless of whether queuing is enabled or disabled
for the FEX. In Cisco NX-OS Release 6.2(2), all FEXs come up with the default hardware queue-limit
value. Any user-defined queue limit that is configured after an ISSU by using the hardware queue-limit
command takes effect even if queuing is not enabled for the FEX.
• No Support on the Cisco Nexus 2248PQ 10-Gigabit Ethernet Fabric Extender
The following sample output shows that FEX queuing is not supported for the Cisco Nexus 2248PQ
10-Gigabit Ethernet Fabric Extender (FEX2248PQ):
