Hi Cisco-NSP,

We have a pair of Cisco Nexus 7000s switches connecting into one Juniper EX4200 switch using a vPC port-channel. On the Juniper side they are using LACP Link Protection (http://www.juniper.net/techpubs/en_US/junos13.3/topics/task/configuration/lacp-link-protection-cli.html <http://www.juniper.net/techpubs/en_US/junos13.3/topics/task/configuration/lacp-link-protection-cli.html>). In the initial turn-up, it was determined that the Cisco side was sending packets across either interface, but the Juniper side would drop any packets sent to the “protected” port on their side. 

Has anyone successfully configured the same setup on the Cisco side? We opened a TAC case but they said it was not possible.
