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. Answer: you should look for CFM Connectivity Fault Management according to metro ethernet forum standards. 802.1ah Ethernet OAM and CFM It comes in two flavors link level fault management or logical level fault management ( roughly single Vlan level EVC in MEF terms). see http://www.cisco.com/en/US/docs/switches/metro/me3400/software/release/12.2_60_ez/configuration/guide/swoam.html CFM over EVC on ES linecards http://www.cisco.com/en/US/docs/routers/7600/install_config/ES40_config_guide/es40_chap4.html#wp1709601 WS-C3560X-48P-L Price WS-C3560X-48P-L Price
