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. Each 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 network 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 the 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 station 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 deletes the S-channel.

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 request to a VSI manager. The VSI manager notifies the bridge to create a VSI interface and apply policies.

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.

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:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view.	interface interface-type interface-number	N/A
3.     Configure the interface to operate in trunk mode.	port link-type trunk	By default, the interface operates in access mode.
4.     Enable EVB.	evb enable	By default, EVB is disabled on an interface.

 

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.	system-view	N/A
2.     Enable LLDP globally.	lldp global enable	By default, LLDP is disabled globally.
3.     Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view.	interface interface-type interface-number	N/A
4.     Enable LLDP on the interface	lldp enable	By default, LLDP is enabled on an interface.
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 disable.

 

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 resources 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 TLV is 0, the VDP packet does not contain a VSI manager's IP address, so the bridge communicates 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.

The value of the VDP resource wait-delay exponent is the larger of the values proposed by the station and bridge through EVB TLV.

When a Pre-Associate, Pre-Associate with Resource Reservation, or Associate request from a station is successfully handled, the VSI manager notifies the bridge to create a VSI interface for the corresponding VM. Then the bridge starts a VDP keepalive timer for the VSI interface. If the bridge receives no keepalive from the station before the timer expires, it releases resources reserved for the association. The VDP keepalive time is calculated as:

VDP keepalive time (seconds) = 1.5 × [ 2^{VDP keepalive} + (2 × ECP maximum retransmission time + 1) × 2^{ECP retransmission} ] × 10^—5.

The value assigned to the VDP keepalive exponent, the ECP maximum retransmission time, and the ECP retransmission exponent are the larger of the values proposed for each by the station and bridge through EVB TLV.

To configure VDP negotiation parameters:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view.	interface interface-type interface-number	N/A
3.     Configure the VDP resource-wait-delay timer exponent.	evb vdp timer resource-wait-delay exponent value	The default is 20.
4.     Configure the VDP keepalive timer exponent.	evb vdp timer keepalive exponent value	The default is 20.

 

Configuring an S-channel

Creating an S-channel

An S-channel is automatically created by CDCP, and the system automatically saves the configuration in the configuration file on the bridge. You can also manually create an S-channel by performing this task. If an (SCID, SVID) pair for an S-channel is created both automatically and manually, the one automatically created takes precedence.

After an S-channel is created, an S-channel interface or S-channel aggregate interface is generated. Removing an S-channel also removes the S-channel interface or S-channel aggregate interface. A manually created S-channel interface or S-channel aggregate interface operates in access mode. An S-channel interface or S-channel aggregate interface that is automatically created through CDCP operates in trunk mode.

An S-channel interface is associated with the S-channel that is created on a Layer 2 Ethernet interface. An S-channel aggregate interface is associated with the S-channel that is created on a Layer 2 aggregate interface.

When you create an S-channel, follow these guidelines:

·     Create an S-channel on an interface with EVB enabled. Otherwise, an error message appears.

·     A default S-channel is created on an interface after EVB is enabled on the interface. Both SCID and SVID are 1.

·     When you manually create an S-channel, do not use the SCID or SVID being used by any other S-channel. Otherwise, an error message appears.

·     To manually create or remove S-channel, disable CDCP that automatically performs these operations.

To create an S-channel:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view.	interface interface-type interface-number	N/A
3.     Create an S-channel.	evb s-channel channel-id [ service-vlan svlan-id ]	By default, only an automatically created default S-channel (with both SCID and SVID as 1) exists on an interface with EVB enabled.

 

Configuring an S-channel interface or S-channel aggregate interface

To configure an S-channel interface:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter S-channel interface view.	interface s-channel interface-number:channel-id	N/A
3.     (Optional.) Configure the expected bandwidth of the S-channel interface.	bandwidth bandwidth-value	By default, the expected bandwidth of an S-channel interface is the default maximum bandwidth of the physical port to which the S-channel interface belongs.
4.     (Optional.) Restore the default settings for the S-channel interface.	default	N/A
5.     (Optional.) Configure a description for the S-channel interface.	description text	The default description information is "interface name Interface."
6.     Bring up the S-channel interface.	undo shutdown	By default, the S-channel interface is up.

 

To configure an S-channel aggregate interface:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter S-channel aggregate interface view.	interface schannel-aggregation interface-number:channel-id	N/A
3.     (Optional.) Configure a description for the S-channel aggregate interface.	description text	The default description information is "interface name Interface."
4.     Bring up the S-channel aggregate interface.	undo shutdown	By default, the S-channel aggregate interface is up.

 

Configuring the RR mode for an S-channel

EVB TLVs exchanged through LLDP allow an EVB station and EVB bridge to negotiate the use of reflective relay. If the EVB bridge supports the RR mode, when the EVB station requests the use of the RR mode, the bridge performs the following tasks:

·     Automatically enables the RR mode for the S-channel.

·     Saves the configuration in the configuration file on the bridge.

You can also manually enable the RR mode for an S-channel by performing this task.

To configure the RR mode for an S-channel:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter S-channel interface view or S-channel aggregate interface view.	interface { s-channel | schannel-aggregation } interface-number:channel-id	N/A
3.     Enable the RR mode for the S-channel.	evb reflective-relay	By default, the RR mode is disabled for an S-channel.

 

Configuring MAC address learning for an S-channel

You can manually disable the MAC address learning function for an S-channel by performing this task.

Follow these restrictions and guidelines when you configure MAC address learning for an S-channel:

·     For an S-channel with the RR mode disabled, do not disable its MAC address learning function. Otherwise, the bridge might fail to forward traffic for VMs on the EVB station.

·     After you disable the MAC address learning function for an S-channel, the bridge will discard packets with an unknown source MAC address.

·     The undo evb mac-learning forbidden command and the mac-address mac-learning enable command must be configured together to avoid communication interruption. For more information about the mac-address mac-learning enable command, see Layer 2—LAN Switching Command References.

To disable MAC address learning for an S-channel:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter S-channel interface view or S-channel aggregate interface view.	interface { s-channel | schannel-aggregation } interface-number:channel-id	N/A
3.     Disable MAC address learning for the S-channel.	evb mac-learning forbidden	By default, the MAC address learning function is enabled for an S-channel.

 

Configuring a VSI interface or VSI aggregate interface

Creating a VSI interface or VSI aggregate interface

IMPORTANT: When the total number of VSI interfaces and VSI aggregate interfaces on the device exceeds 512, make sure the VDP keepalive exponent is larger than the default value. Otherwise, some VSI interfaces or VSI aggregate interfaces might be automatically deleted.

 

A VSI interface is created on an S-channel interface through this task, and it is a subinterface of the S-channel interface. A VSI aggregate interface is created on an S-channel aggregate interface, and it is a subinterface of the S-channel aggregate interface. Removing an S-channel also removes all its VSI interfaces and VSI aggregate interfaces.

VSI interfaces or VSI aggregate interfaces are typically created by a VSI manager. You can create a VSI interface or VSI aggregate interface, or modify its Pre-Associate and Associate properties through this task.

To create a VSI interface or VSI aggregate interface:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter S-channel interface view or S-channel aggregate interface view.	interface { s-channel | schannel-aggregation } interface-number:channel-id	N/A
3.     Create a VSI interface or VSI aggregate interface.	evb vsi vsi-local-id { association | pre-association }	By default, no VSI interface or VSI aggregate interface exists on an S-channel.

 

Configuring VSI filters

The EVB bridge uses VSI filters to identify VSI traffic. Typically a VSI manager assigns filters. You can manually create or remove a VSI filter.

A VSI filter contains a set of VID values, MAC addresses, and group ID values. EVB supports the following filter info formats:

·     VLAN ID.

·     VLAN ID + MAC.

·     Group ID + VLAN ID.

·     Group ID + VLAN ID + MAC.

When you configure a VSI filter on a VSI interface, follow these guidelines:

·     For the VSI filter configuration to take effect, make sure the S-channel interface to which the VSI interface belongs operates in trunk mode.

·     When you create a VSI filter, the following interfaces automatically permit the VLAN contained in the VSI filter:

?     The S-channel interface to which the VSI interface belongs.

?     The Layer 2 Ethernet interface where the S-channel that is associated with the S-channel interface is created.

·     When you delete a VSI filter that contains information about a VLAN on a VSI interface, the other VSI filters on all VSI interfaces of an S-channel interface might not contain the VLAN. If they do not, the S-channel interface automatically denies traffic from the VLAN that is configured on the VSI filter. The same rule takes effect on Layer 2 interfaces associated with S-channels.

·     When you delete a VSI filter, the following interfaces automatically deny the VLAN in the filter if the VSI filters on the other VSI interfaces created on the same S-channel interface do not contain the VLAN:

?     The S-channel interface to which the VSI interface belongs.

?     The Layer 2 Ethernet interface where the S-channel that is associated with the S-channel interface is created.

·     Do not create a VSI filter that contains the same VLAN on the same VSI interface or on other VSI interfaces that belong to the same S-channel interface. If you do so, the system displays an error message.

·     Disabling MAC address learning for an S-channel prevents the traffic from the VSI from being forwarded if the VSI filter contains the VLAN to which the traffic belongs.

·     Activate a VSI interface after configuring a VSI filter, and deactivate a VSI interface before removing a VSI filter.

When you configure VSI filters on a VSI aggregate interface, follow these guidelines:

·     For the VSI filter configuration to take effect, make sure the S-channel aggregate interface to which the VSI aggregate interface belongs operates in trunk mode.

·     When you create a VSI filter, the following interfaces automatically permit the VLAN contained in the VSI filter:

?     The S-channel aggregate interface to which the VSI aggregate interface belongs.

?     The Layer 2 aggregate interface where the S-channel that is associated with the S-channel aggregate interface is created.

·     When you delete a VSI filter, the following interfaces automatically deny the VLAN in the filter if the VSI filters on the other VSI aggregate interfaces created on the same S-channel aggregate interface do not contain the VLAN:

?     The S-channel aggregate interface to which the VSI aggregate interface belongs.

?     The Layer 2 aggregate interface where the S-channel that is associated with the S-channel aggregate interface is created.

·     Do not create a VSI filter that contains the same VLAN on the same VSI aggregate interface or on other VSI aggregate interfaces that belong to the same S-channel aggregate interface. If you do so, the system displays an error message.

·     Activate a VSI aggregate interface after configuring a VSI filter, and deactivate a VSI aggregate interface before removing a VSI filter.

To configure a VSI filter:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter VSI interface view or VSI aggregate interface view.	interface { s-channel | schannel-aggregation } interface-number:channel-id.vsi-local-id	N/A
3.     Configure a VSI filter.	evb vsi filter [ group group-id ] vlan vlan-id [ mac mac-address ]	By default, no VSI filter is configured.

 

Activating a VSI interface or VSI aggregate interface

Configurations such as traffic monitoring (see ACL and QoS Configuration Guide) on a VSI interface or VSI aggregate interface take effect only after the VSI interface or VSI aggregate interface is activated. When a VSI interface or VSI aggregate interface is not activated, only configure filters on the VSI interface or VSI aggregate interface.

Activate a VSI interface or VSI aggregate interface after configuring a VSI filter, and deactivate a VSI interface or VSI aggregate interface before removing a VSI filter.

To activate a VSI interface:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter VSI interface view.	interface s-channel interface-number:channel-id.vsi-local-id	N/A
3.     (Optional.) Configure the expected bandwidth of the VSI interface.	bandwidth bandwidth-value	By default, the expected bandwidth of a VSI interface is the default maximum bandwidth of the physical port to which the VSI interface belongs.
4.     (Optional.) Restore the default settings for the VSI interface.	default	N/A
5.     (Optional.) Configure a description for the VSI interface.	description text	The default description information is "interface name Interface."
6.     Activate the VSI interface.	evb vsi active	By default, no VSI interface is activated.

 

To activate a VSI aggregate interface:

 

Step	Command	Remarks
1.     Enter system view.	system-view	N/A
2.     Enter VSI aggregate interface view.	interface schannel-aggregation interface-number:channel-id.vsi-local-id	N/A
3.     (Optional.) Configure a description for the VSI aggregate interface.	description text	The default description information is "interface name Interface."
4.     Activate the VSI aggregate interface.	evb vsi active	By default, no VSI aggregate interface is activated.
