Table 13-2 Operational States Operational State Up Down Trunking Description Interface is transmitting or receiving traffic as desired. To be in this state, an interface must be administratively up, the interface link layer state must be up, and the interface initialization must be completed. Interface cannot transmit or receive (data) traffic. Interface is operational in TE or TF mode.
