18.2.2 Configuring the L2 protocol frame transparency functionality
(1) Setting BPDU forwarding functionality
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) Setting EAPOL forwarding functionality
Points to note
The settings for this functionality take effect for each switch. When set, EAPOL
frames are forwarded for all VLANs.
EAPOL forwarding 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.
