Hello,

I'm trying to create test environment on Sonic-VS with `DellEMC-S5248f-P-10G` as a testing model.

Using 202205 Sonic branch.

Configuring VS to act as DellEMC-S5248f-P-10G:

sonic-cfggen -H -k DellEMC-S5248f-P-10G --preset l1 > /etc/sonic/config_db.json

reboot

show platform summary
Platform: x86_64-kvm_x86_64-r0
HwSKU: DellEMC-S5248f-P-10G
ASIC: vs
ASIC Count: 1
Serial Number: N/A
Model Number: N/A
Hardware Revision: N/A

The problem is that it seems Sonic is not mapping VM interfaces to switchports correctly.

VM has 3 network interfaces so according to lanemap.ini second and third VM interface should be mapped to ports Ethernet0 and Ethernet1 accordingly. But these ports are shown as down:

Interface Lanes Speed MTU FEC Alias Vlan Oper Admin Type Asym PFC
----------- --------------- ---------- ----- ----- --------------- ------ ------ ------- ------ ----------

Ethernet0 49 10G 9100 N/A tenGigE1/1/1 routed down up N/A N/A
Ethernet1 50 10G 9100 N/A tenGigE1/1/2 routed down up N/A N/A

Also for some reason Ehternet35 is shown as up:

show interfaces status Ethernet35
Interface Lanes Speed MTU FEC Alias Vlan Oper Admin Type Asym PFC
----------- ------- ---------- ----- ----- ------------ ------ ------ ------- ------ ----------
Ethernet35 32 4294967.3G 9100 N/A tenGigE1/9/4 routed up up N/A N/A

If Ethernet0 or Ethernet1 are given an IP address, it is not reacheable.

If I add IP address to Ethernet35 - it could be reached.

I guess there's something with vswitch configuration, but I'm not sure where to start debugging this.

Appreciate any help.

Thank you.

I must add that with different hardware like Force10-S6000 ports are working. I can see 2 ports in Up state and network configuration works.

Hi ,

For sonic-vs, 2 hardware SKUs are supported ( Force10-S6000 , brcm_gearbox_vs).

Please refer https://github.com/sonic-net/sonic-buildimage/tree/master/device/virtual/x86_64-kvm_x86_64-r0 and README.md

Thanks

Chitra
