Question: does Cisco support "Link loss WS-C3560X-48P-L WS-C3560X-48P-L forwarding" on one of its platforms? Is there maybe any other similar feauture ( i.e. like BFD over ethernet) which could do the same thing? foe example: LAN1---cisco1-----layer2_NETWORK---cisco2--- LAN2 some feature which could detect failure somewhere in a layer2 network between cisco1 and cisco2 and then bring down ports toward LAN1 and LAN2.
