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.

Table 2: Command output

Field	Description
EVB mode	EVB mode: bridge—EVB bridge. station—EVB station.
BGID status	Support for Group ID on the EVB bridge: Supported. Not supported.
Local RR capability	Support for the RR mode on the EVB bridge: Supported. Not supported.
Local RR status	RR status on the EVB bridge after EVB TLV negotiation.
Remote SGID status	Support for Group ID on the EVB station: Supported. Not supported.
Remote RR request status	Whether or not the EVB station has requested the RR mode: Requested. Not requested.
Remote RR status	Whether or not the EVB station has enabled the RR mode after EVB TLV negotiation: Enabled. Disabled. Unknown.
Max ECP retry time	Maximum ECP retransmission times in this format: Local negotiation value/Remote negotiation value/Operative value. NA means no value is set on the remote EVB station.
ULPPDU retransmission exponent	ECP retransmission exponent in this format: Local negotiation value/Remote negotiation value/Operative value. NA means no value is set on the remote EVB station.
Resource wait-delay exponent	VDP resource-wait-delay exponent in this format: Local negotiation value/Remote negotiation value/Operative value. NA means no value is set on the remote EVB station.
Reinit keep-alive exponent	VDP keepalive exponent in this format: Local negotiation value/Remote negotiation value/Operative value. NA means no value is set on the remote EVB station.
