Description: The MAC source address placed to Ehernet Header of IP forwarded packet.
What is rlInetFftL2InfoSrcMacAddress?
This read-only PhysAddress is the MAC source address the switch places in the Ethernet header of an IP-forwarded packet. It's operationally relevant because a wrong source MAC here can cause downstream switches or hosts to build incorrect MAC-address-table entries or reject frames due to source validation. For example, if a downstream firewall with strict source-MAC filtering starts dropping forwarded traffic, checking this field confirms whether the switch is stamping the expected source address.
