Dual TOR with single NIC server, server can not ping active TOR

[Farhad Sultani]

I am running SONiC in Arista 7260cx3, in Dual TOR with single NIC server, server can ping TOR_A (standby) and can not ping TOR_B (active). The server is connected with breakout muxcable (Y-cable vendor=Credo model=CACL15321P2PA1MS) to the TOR_A and TOR_B. Same scenario is running in Arista 7050cx3 with SONiC NOS, server can ping both TOR_A and TOR_B.
