Introduction
This document describes how to validate Layer 2 hardware programming and forwarding on Catalyst 9400 Series switches.
Prerequisites
Requirements
There are no specific requirements for this document.
Components Used
The information in this document is based on the Catalyst 9400 (UADP 2.0) series switch.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
Background Information
- The Catalyst 9400 Supervisor1 (C9400-SUP-1) has 3 UADP 2.0 forwarding ASICs (0, 1, 2).
- Each UADP 2.0 forwarding ASIC has:
- A dual Core (0, 1) - this did not exist in previous generations of UADP 2.0 ASICS.
- SIFs (Stack Interfaces) - used to connect to the other 2 UADP 2.0 ASICs via an internal stack ring.
- NIFs (Network Interfaces) - used to connect to 1 or more Line cards via the backplane.
- All packet forwarding decisions for the Line cards and the Supervisor uplink interfaces are made by the 3 UADP 2.0 forwarding ASICs on the active Supervisor.
- The Line cards used in this example have 1 Line card single core stub ASIC which is not involved in packet forwarding decisions.
- The Line card stub ASIC on the Line card connects to 1 or more of the 3 UADP 2.0 forwarding ASICs on the Supervisor via the backplane.
- The 3 UADP 2.0 forwarding ASICs on the Supervisor make all packet forwarding decisions.

Etherchannel Programming
In these Etherchannel programming example outputs, the RP programs the FP, the FP programs the FED, the FED then programs the Supervisor forwarding ASIC hardware. RP software entries are stored as objects in the object database and the FP software entries are stored as asynchronous objects in the object database.

Successful Hardware Programming
All features (whether it be a mac address, an interface, a vlan, and so on) are stored in the object database and programmed into the hardware as objects.
The RP programs the FP, the FP programs the FED, and the FED then finally programs the Supervisor forwarding ASIC hardware. RP software entries are stored as objects in the object database and the FP software entries are stored as asynchronous objects in the object database.
When the FP programs the FED (which in turn programs the Supervisor forwarding ASIC), the FED sends an acknowledgement back to the FP. The FP then forwards it to the RP to indicate that the hardware programming completed successfully. If FED hardware programming is missing or incorrect you can use this next command to check for issues and/or acknowledgements.
C9400#show platform software object-manager fp active statistics Forwarding Manager Asynchronous Object Manager Statistics Object update: Pending-issue: 0, Pending-acknowledgement: 0 Batch begin: Pending-issue: 0, Pending-acknowledgement: 0 Batch end: Pending-issue: 0, Pending-acknowledgement: 0 Command: Pending-acknowledgement: 0 Total-objects: 3269 Stale-objects: 0 Resolve-objects: 0 Error-objects: 0 Paused-types: 0
If the previous command shows non-zero objects in pending issue state, use this command to find the object number involved:
C9400#show platform software object-manager fp active pending-issue-update
Then use this command to determine the stuck process associated with the object number:
C9400#show platform software object-manager fp active object {object#}
On the RP side, use this command to check for delete pending (Del Pend) for an object that the FP did not acknowledge.
C9400#show platform software object-manager rp active object-type-info

Supervisor Statistics - Supervisor to Line Card Data Path
Check the active Supervisor UADP 2.0 forwarding ASIC statistics that are associated with a specific front panel interface. In this example, the interface Gig1/0/13 is used.
Output Example:
- Check which interfaces on the Line card are part of the same port group.
- Each port group shared 8 Gbps of bandwidth from the Line card stub ASIC towards the Supervisor forwarding ASIC.
- Each port group is associated with one of the SLI (System Link Interface) on the Line card stub ASIC towards the Supervisor forwarding ASIC.

Line Card Statistics - Supervisor to Line Card Data Path
Check the Line card Line card stub ASIC statistics that are associated with a specific front panel interface. In this example, the interface Gig1/0/13 is the focus.
Output example:
-
Packets received from Gig 1/0/13, enter the Network Interface receiving port and progress through IQS to the stack interface.
-
From there, a packet either goes out the stack interface to another Supervisor ASIC , or comes back through the SQS, AQM, EQC, ESM, RWE, and then goes out the Network interface transmit of Gig 1/0/13.
-
Packets sent from other Supervisor ASICs interfaces that egress out of Gig 1/0/13 enter Sif and then pass through SQS, AQM, EQC, ESM, RWE and then goes out the NifTx of Gig 1/0/13.
-
For AQM there are 8 Tx queues. If you see drops from these queues, you can use this command to determine which one of the queues is experiencing drops: show platform hardware fed active goes queue stats interface Gig 1/0/13

Check the flow control status from a Line card perspective for the front panel interface. This helps identify any congestion on the interface.
- Values are "-" when there is no flow control otherwise the queue number experiencing flow control (congestion) is indicated.
- Flow control received by the interface is passed from the Line card ASIC on the Line card to the Supervisor ASIC on the Supervisor where AQM drops typically be seen on the Supervisor Supervisor ASIC. The OCI (Out-of-band Control Interface) is the internal communication channel between the Line card and active Supervisor that is used to signal the flow control from Line card to Supervisor.

Check which interfaces on the Line card are part of the same port group which shares 8 Gbps of bandwidth from the Line card stub ASIC on the Line card towards the Supervisor forwarding ASIC on the active Supervisor. Each port group is associated with one of the SLI (System Link Interface) on the Line card stub ASIC towards the Supervisor.
