Usage guidelines

Follow these guidelines when you enable or disable EVB on an interface:

• Do not enable EVB on a member port of an aggregation group, or add a member port with EVB enabled into an aggregation group. Otherwise, an error message appears.

• Restore all default settings for an interface before enabling EVB on the interface.

• A default S-channel is created on an interface after EVB is enabled on the interface, with both SCID and SVID as 1. After an S-channel is created, an S-channel interface or S-channel aggregate interface is created and operates in access mode.

• Do not configure VLAN settings or enable any other Layer 2 protocol on an interface with EVB enabled.

• Delete all non-default S-channels on an interface before disabling EVB on the interface. The default S-channel is deleted after EVB is disabled.

• Do not enable both EVB and QinQ on the same interface.

• Do not create a service instance for an interface enabled with EVB, and vice versa.

Examples

# Enable EVB on FortyGigE 1/0/1.

<Sysname> system-view
[Sysname] interface FortyGigE 1/0/1
[Sysname-FortyGigE1/0/1] evb enable

# Enable EVB on Bridge-Aggregation 1.

<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] evb enable
