Configuring EVB
Overview
Edge Virtual Bridging (EVB) allows virtual machines (VMs) on a physical server to obtain bridge relay
services through a common bridge port. It enables coordinated configuration and management of
bridge services for VMs.
Data center virtualization includes network virtualization, storage virtualization, and server
virtualization. Server virtualization uses specific virtualization software such as VMware to create
VMs on a single physical server. Ea ch VM operates independently and has its own operating system ,
applications, and virtual hardware environments, as shown in Figure 1.
Figure
1 Server virtualization
VMs on a physical server communicate with each other or with the outside net work through a Virtual
Ethernet Bridge (VEB). VEBs are implemented through software or hardware such as NICs. Both
implementation methods have the following limitations:
• Lack of traffic monitoring capabilities such as packets statistics, traffic mirroring, and
NetStream.
• Lack of network policy enforcement capabilities, such as QoS.
• Lack of management scalability , especially in unified deployment of the internal server network
and the external network.
EVB solves these limitations. It uses a physical switch (called EVB bridge) to switch traffic for VMs on
a directly connected physical server (called EVB station). EVB implements traffic monitoring,
network policy enforcement, and unified network deployment and management for VMs.

Basic concepts
Figure 2 shows the components on the EVB station and EVB bridge.
Figure 2 EVB architecture
• Edge Relay (ER)—Transfers packets between one URP and one or more DRPs. An ER has
one or more DRPs and one URP. Both URP and DRPs are called ER ports. An EVB station can
have multiple ERs.
• S-channel—A point-to-point S-VLAN established between a Port-mapping S-VLAN component
in an EVB station and a Port-mapping S-VLAN component in an EVB bridge. An S-channel
corresponds to the URP of an ER. On an EVB bridge, the end point of an S-channel is known as
an S-channel interface. An S-channel is identified by the S-VLAN Identifier (SVID) and the
S-channel Identifier (SCID), and the two values together are called an (SCID, SVID) pair.
• Virtual Station Interface (VSI)—A port on a VM that directly connects to the DRP of an ER. A
VSI is associated with a logical entity called VSI instance, which is identified by th e VSI Instance
Identifier (VSIID). A VSI is associated with a virtual interface called VSI interface on the EVB
bridge port to implement VM traffic management and policy configuration. A VSI interface can
be considered a subinterface of an S-channel.
• Reflective Relay (RR)—An operation mode in which a received frame on a port that supports
this function can be forwarded out of the same port. The EVB bridge uses this mode to forward
traffic among VMs on an EVB station, as shown in Figure 2.
EVB working mechanism
An EVB station and an EVB bridge go through the following steps to implement VM traffic
management:
1. Use the S-channel Discovery and Configuration Protocol (CDCP) to establish an S-channel.
CDCP is used to configure S-channels between stations and bridges. When a sta tion creates or
deletes an S-channel, CDCP sends a CDCP TLV in an LLDP packet that is addressed using the
Nearest non-TPMR Bridge address to the bridge. The bridge creates or del etes the S-cha nnel.
2. Exchange EVB TLVs through LLDP to negotiate EVB capabilities for the S-channel, such as
RR, ECP parameters, and VDP parameters.
3. Use the VSI Discovery and Configuration Protocol (VDP) to associate the VSIs of VMs with the
bridge port.
The bridge uses the VSI interfaces to manage traffic for VMs.
VDP manages the association between a VSI and a station-facing bridge port (SBP) on a
bridge. VDP uses the Edge Control Protocol (ECP) to carry VDP TLVs. A VDP TLV comprises
the VSIID, VSI type, and VSI version.
When a station creates a VM, it sends a VDP pre-associate, pre-associate with resource
reservation, or associate packet to the bridge. The bridge sends the req uest to a VSI manager.
The VSI manager notifies the bridge to create a VSI interface and apply policies.
3
When a station shuts down a VM, it sends a VDP de-associate packet to the bridge. The bridge
sends the request to the VSI manager. The VSI manager notifies the bridge to delete the VSI
interface.
Protocols and standards
IEEE P802.1Qbg/D2.2, Draft Standard for Local and Metropolitan Area Networks—MAC Bridges
and Virtual Bridged Local Area Networ ks—Amendment XX: Edge Virtual Bridging.
Configuration restrictions and guidelines
When you configure EVB, follow these restrictions and guidelines:
Hardware restrictions and guidelines
EVB is applicable only to interfaces on the following interface modules:
• EC interface modules.
• SE interface modules:
{ LSUM2GP44TSSE0(JH191A, JH199A).
{ LSUM2GT48SE0(JH192A, JH200A).
{ LSU1CGC2SE0(JG916A).
• SF interface modules.
• SG interface modules.
Traffic received from a port enabled with EVB can be forwarded only through interface cards that
support EVB.
Software restrictions and guidelines

Do not create a service instance for an interface enabled with EVB, and vice versa.
Interfaces enabled with EVB cannot operate in route mode. For more information about Ethernet
interface link modes, see Interface Configuration Guide.
After you enable EVB on a Layer 2 Ethernet interface or a Layer 2 aggregate interface in a VLAN, the
interface does not support Layer 3 services.
4
After you enable EVB on a Layer 2 Ethernet interface or a Layer 2 aggregate interface in a VLAN, the
interface does not support Layer 2 multicast services.
After you add an interface to a multiport unicast MAC address entry, the interface cannot forward
traffic received from interfaces enabled with EVB. For more information about multiport unicast MAC
address entries, see Layer 2—LAN Switching Configuration Guide.
Do not configure an interface enabled with EVB as the source or destination port for a mirroring
group. For more information about mirroring groups, see Network Management and Monitoring
Configuration Guide.
EVB configuration task list
This document only describes EVB bridge configuration. For information about EVB station
configuration, see the station manual.
Tasks at a glance
Enabling EVB
Configuring LLDP
(Optional.) Specifying a default VSI manager
(Optional.) Configuring VDP negotiation parameters
(Optional.) Configuring an S-channel:
• Creating an S-channel
• Configuring an S-channel interface or S-chan
nel aggregate interface
• Configuring the RR mode for an S-channel
• Configuring MAC address learning for an S-channel
(Optional.) Configuring a VSI interface or VSI aggregate interface:
• Creating a VSI interface or VS
I aggregate interface

Enabling EVB
Perform this task to enable EVB on an interface that directly connects to a station.
A default S-channel is created on an interface after EVB is enabled on the interface. Both SCID and
SVID are 1. After an S-channel is created, an S-channel interface or S-channel aggregate interface
is created and operates in access mode.
To enable EVB:

Configuring LLDP
EVB uses LLDP to transmit CDCP TLVs, and CDCP TLVs are carried by the LLDP packet that is
addressed using the Nearest non-TPMR Bridge address, so you must configure LLDP.
For detailed information about the lldp global enable, lldp enable and lldp agent
nearest-nontpmr admin-status commands, see Layer 2—LAN Switching Command Reference.
To configure LLDP:
Step Command Remarks
1. Enter system view.

5. Configure the Nearest
non-TPMR Bridge agent for
LLDP to operate in TxRx
mode.
lldp agent nearest-nontpmr
admin-status txrx
The default mode is

.
Specifying a default VSI manager
When the bridge receives a VDP packet (except for a De-Associate packet) from a station, it
contacts the VSI manager specified in the VDP packet to get VSI interface resource s and policies for
the station.
The VSI manager ID TLV in a VDP packet carries the VSI manager's IP address. If the value for the
TL V is 0, the VDP packet d oes not contain a VSI manager's IP address, so the bridge comm unicates
with the specified default VSI manager .
To specify a default VSI manager:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Specify a default VSI
manager.
evb default-manager
{ { ip
ip-address |
ipv6
ipv6-address |
name
name } [
port
port-number ]
|
local-server }
By default, no default VSI
manager is specified.
Configuring VDP negotiation parameters
After a station sends a VDP request other than a De-Associate request to the bridge, the bridge
requests the VSI interface resources and policies from the VSI manager. If the bridge receives no
response from the VSI manager before the VDP response-wait-delay time expires, the VDP
negotiation fails. The VDP response-wait-delay time on the EVB bridge is calculated as:
VDP response-wait-delay time (seconds) = 2
VDP resource-wait-delay
× 10—5.
