Release Notes

Known Behavior
When installing and configuring the C9010 and C1048P, note the following hardware and software behavior and restrictions.
Known Hardware Behavior
● The port numbering on C9010 line-card ports is 0-based; the lowest-numbered port is 0. The port numbering on C1048P PE
ports is 1-based; the lowest-numbered port is 1.
On both C9010 line cards and C1048P, N20xx, and N30xx PEs, odd-numbered ports are located in the upper row.
● You can connect up to 40 C1048P, N20xx, or N30xx port extenders (standalone and stacked) to a C9010 switch.
● While the C1048P, N20xx, or N30xx boot up in standalone or stacking mode, the Stack Master LED is solid green. After the
PEs boots up, the Stack Master LED is off if it operates as a stack member or stack standby. The LED stays solid green if
the PE operates as a stack master or in standalone mode.
● If you split a PE stack in a daisy-chain topology into two sub-stacks and each sub-stack has a PE uplink to the controlling
bridge, the C9010 detects the stack split and generates an alarm. System administrator intervention is required to diagnose
and correct the split condition; for example, check cable connections or reboot stack units to reactivate each PE stack.
● To locate a C1048P, N20xx, or N30xx, use the location-led pe pe-id stack-unit unit-number {on|off}
command to illuminate the Power/Locator LED on the PE. When the LED is turned on, it blinks green; when the LED setting
is turned off, it displays solid green.
● You can use non-Dell EMC qualified cables, adapters, and optics in a C9010 switch and C1048P, N20xx, or N30xx port
extender, but Dell EMC Networking does not guarantee their performance. If you plug a non-Dell EMC qualified optic into a
port, the Dell EMC Networking OS detects it and makes it operational. The system displays a syslog message similar to the
following:
%C9000LC0640:8 %IFAGT-5-UNSUP_OPTICS: Non-qualified optics in slot 8 port 1
NOTE:
Non-Dell EMC qualified 40G transceivers are not supported on the C9010. If you insert a non-Dell EMC qualified
40G transceiver into a C9010 40GbE port, the switch places the interface in an error-disabled (operationally down) state
and generates a syslog message, such as: %C9000LC0640:8 %IFAGT-2-TRANSCEIVER_UNSUPPORTED_ERROR:
Transceiver in slot 8 port 4 unrecognized, putting interface in operational-down
state.
To verify the error-disabled status of an interface, enter any of the following show commands. The command outputs show
examples of error-disabled 40GbE ports 8/0 and 8/4.

Known Software Behavior
● On the C9010, OpenFlow supports only the scaled-l3-hosts hardware forwarding-table mode (UFT mode 3), providing a
unified forwarding table (UFT) of:
○ L2 MAC entries: 160K
○ L3 host entries: 144K
○ L3 route entries: 16K
