Port-Channel Issue: SP-5-CANNOT_BUNDLE_LACP

Max Wooks

I'm having an issue with the port-channel coming up. Right now it's "down down". I'm not really sure why. All other port-channels on the 6500's in VSS work fine. This one seems to be giving me an issue though.

-Both interfaces that are using this port-channel are "up up".

-I've done "shut's, no shut's" on all interfaces involved.

sh etherchannel summary

Flags:  D - down        P - bundled in port-channel

        I - stand-alone s - suspended

        H - Hot-standby (LACP only)

        R - Layer3      S - Layer2

        U - in use      N - not in use, no aggregation

        f - failed to allocate aggregator

        M - not in use, no aggregation due to minimum links not met

        m - not in use, port not aggregated due to minimum links not met

        u - unsuitable for bundling

        d - default port

Thank you for your help.
