Configuring EVB 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. Overview 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.
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.
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 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. Protocols and standards IEEE P802.1Qbg/D2.
Step Command Remarks By default, EVB is disabled on a bridge port. 3. Enable EVB. After EVB is enabled, a default access-type S-channel with both SCID and SVID as 1 is automatically created on this port. evb enable 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.
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 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) = 2VDP resource-wait-delay × 10—5.
To create an S-channel: Step Command Remarks 1. Enter system view. system-view N/A 2. Enter Layer 2 Ethernet interface view. interface interface-type interface-number N/A 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 a port with EVB enabled. 3. Configuring a description for an S-channel interface Step Command Remarks 1. Enter system view. system-view N/A 2.
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 By default, the MAC address learning function is enabled for an S-channel. IMPORTANT: • For an S-channel with RR mode Disable MAC address learning for the S-channel. 3. evb mac-learning forbidden disabled, do not disable its MAC address learning function. Otherwise, the bridge might fail to forward traffic for VMs on the EVB station.
• When a filter configured on a VSI contains information about a VLAN, you cannot configure the filter on the same VSI again or on other VSIs of the S-channel interface to which the VSI belongs. Otherwise, the system prompts an error. • If the VSI filter is a set of VID values, and the MAC address learning function for the corresponding S-channel is disabled, traffic for the VSI cannot be forwarded. • Activate a VSI after configuring a VSI filter, and deactivate a VSI before removing a VSI filter.
