25.6.2 Configuring L2 protocol frame transparency functionality

<Structure of this section>

(1) Configuring BPDU Forwarding Features

Points to note

The settings for this functionality take effect for each switch. When set, BPDUs are forwarded for all VLANs.

BPDU forwarding functionality needs to be set after stopping the Spanning Tree Protocol for the Switch.

Command examples

  1. (config)# spanning-tree disable

    (config)# l2protocol-tunnel stp

    Sets BPDU forwarding functionality. The Spanning Tree Protocol is stopped first, and then the BPDU forwarding functionality is set. The Switch forwards BPDUs without handling them as protocol frames.

(2) Configuring EAPOL Forwarding Features

Points to note

The settings for this functionality take effect for each switch. When set, EAPOL frames are forwarded for all VLANs.

EAPOL forwarding functionality and IEEE 802.1X cannot be used at the same time.

Command examples

  1. (config)# l2protocol-tunnel eap

    Sets EAPOL forwarding functionality. The Switch forwards EAPOL frames without handling them as protocol frames.
