Table 1: show edge-virtual-bridging Output Field Descriptions

Field Name

Field Description


Switch interface configured for EVB.

Interface input ECP Packets

Number of ECP packets received by the switch. ECP is a Layer 2 protocol that is used to carry VSI Discovery and Configuration Protocol (VDP) messages.

Interface output ECP Packets

Number of ECP packets sent by the switch. ECP is a Layer 2 protocol that is used to carry VDP messages.

Forwarding Mode

Mode by which packets are forwarded to their destination.

The value for forwarding mode is either Standard (meaning the forwarding is done through 802.1Q) or Reflective-relay, meaning that both the source and destination addresses are located on the same VM server.


Retransmission timer exponent (RTE) is an EVB interface attribute used to calculate the minimum VDP protocol data unit (PDU) retransmission time.

Number of VSIs

Number of virtual station interfaces on the switch connected to the VEPA.


EVB protocols currently enabled. The values can be VDP, ECP or RTE. Protocols are configured during the capabilities exchange via an EVB type, length, and value (TLV) carried by the Link Layer Discovery Protocol (LLDP) between the switch and the server.

VSI profile

EVB profile including parameters that uniquely identify each VSI entry (VSI manager, VSI type, VSI version, VSI instance, VSI state).

Filter Name

Name of the filter defined in the firewall stanza.


Number of packets and bytes that have satisfied the match conditions defined by the filter.
