Refer to the exhibit. After an engineer configures an EtherChannel between switch SW1 and switch SW2, this error message is logged on switch SW2:SW2#09:45:32: %PM-4-ERR_DISABLE: channel-misconfig error detected on Gi0/0, putting Gi0/0 in err-disable state09:45:32: %PM-4-ERR_DISABLE: channel-misconfig error detected on Gi0/1, putting Gi0/1 in err-disable stateBased on the output from switch SW1 and the log message received on switch SW2, what action should the engineer take to resolve this issue?

TOS = Trunk Operational StatusTAS = Trunk Administrative StatusTNS = Trunk Negotiated StatusTOT = Trunk Operational Trunk-EncapsulationTAT = Trunk Administrative Trunk-EncapsulationTNT = Trunk Negotiated Trunk-EncapsulationOperational = What we are doing at this momentAdministrative = How we configured itNegotiated = What we asked for during the negotiationTAS is configured as Auto, so if other side is trunk and this side is auto then it will form trunk. There is no need for B. If we look for trunk-encapsulation TAT, it's set for ISL. It will not work for .1q.
