6504e, need to make Etherchannel down when any member is down

[hetene_kaz]

Hi all,

I have 6504e with 2 Etherchannels (2x1Gbps links in each), active and standby, BGP over each towards ISP.

Need to make etherchannel up ONLY when both members are up, to make etherchannel always have a capacity of 2Gbps.

Any idea?

This is supported for LACP Etherchannels.

This feature is called Minimum-Links

It allows you to configure the minimum number of member ports that must be in the link-up state and bundled in the EtherChannel for the port channel interface to transition to the link-up state.

int po1
port-channel min-links x (X is you value)

So in your instance it should be

int po1
port-channel min-links 2

That way if 1 fails, you do not have a minimum of 2, and the port channel will go down

This seems to be only available with LACP
