Parameters

interface: Specifies an interface. If you do not specify an interface, the command displays EVB TLV negotiation information for all interfaces with EVB enabled.

interface-type { interface-number | interface-number:channel-id }: Specifies a Layer 2 Ethernet interface, Layer 2 aggregate interface, S-channel interface, or an S-channel aggregate interface by its type and number. The interface-number argument specifies a Layer 2 Ethernet interface or Layer 2 aggregate interface. The interface-number:channel-id argument specifies an S-channel interface or S-channel aggregate interface.
