1- When we try to create 2 port of 400G using MPAs C57-MPA-2D4H-S only on instance 2 and instance 3 the ports are only created on Instance 2. 2- Instance 3 only create one port. 3- It provide the following error: %PLATFORM-VEEA-3-BCMDPA_L1_PORT_CREATION_FAILURE : bcmdpa l1 port create failed, ifname: FourHundredGigE0_0_3_2, unit:0...
1- We got this issue when there are 3 MPAs are connected. 2- If you remove MPA1 All ports on MPA2 and MPA3 can be created 3- If you have MPA1 connected you can only create 2 port on one of the MPAs 2 or 3. 4- This issue is not happening on version 7.5.2 5- Configuration used: hw-module profile npu native-mode-enable hw-module port-range 0 1 instance 2 location 0/0/CPU0 mode 400 hw-module port-range 0 1 instance 3 location 0/0/CPU0 mode 400 hw-module port-range 2 3 instance 2 location 0/0/CPU0 mode 400 hw-module port-range 2 3 instance 3 location 0/0/CPU0 mode 400 hw-module profile qos hqos-enable
NA
Minimum requirement to hit the issue: 1. All 3 MPA’s must be inserted and must be up 2. Configure hw-mod command for MPA 0/2 and 0/3 to create 2x400 ports (MPA 0/1 is static and hosts only 4x100 ports) Failure signature: 1. Always last 400Gig port out of MPA 0/3 fails to come up. Scenarios 1: 1. Insert MPA 0/1: Test : Pass * Ports will come up (4x100Gig) 2. Now Insert MPA 0/2: Test Pass * Create 2x400 ports in MPA 0/2 using hw-mod command. Both ports in MPA 0/2 come up. 3. Now insert MPA 0/3: * MPA will come up * Create 2x400 ports in MPA 0/3 using hw-mod command. Only first 400Gig port will come up. Second port doesnot get created
