Hi! i have some problem with configuring MEC on Cisco Catalyst 6880.
Configuration: 2x6880 customized technology VSS, when I want to connect to the server MEC to them (assuming the correct setup etherchannel on the server side), the interfaces on a switch are not raised, only helps to pull the transceiver and insert it again, then everything starts to work. If you do not connect technology MEC to two different chassis, but to one, then such problems do not arise all starts to work immediately.
Thanks for answer, but in "Release 15.1SY Supervisor Engine 720 Software Configuration Guide" says that the implementation of MEC possible between servers - this configuration works, but only after reinstalling the transceivers in ports, ports are raised and everything works. Between the server and the switch operating on the VSS technology is configured with etherchannel protocol LACP. If I understand correctly, it is best to connect the server to two different chassis mood VSS, and one of them, I understand you?
Correct, if your serves have dual NICs then you connect each to 2 different switche (VSS) using LACP or mode on. Of LACP does not work try mode on and test. Some server do work better with mode on. Are these physical servers or VMs?
Can you post the portchannel config and physical interfaces config from the VSS set?
