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.
Do not enable both EVB and VLAN mapping, both EVB and TRILL, or both EVB and QinQ on the same
interface.
Do not create a service instance for an interface enabled with EVB, and vice versa.
Do not assign interfaces enabled with EVB and not configured with the
trill evb-support
command to the
same VLAN as interfaces enabled with TRILL. For more information about TRILL, see
TRILL Configuration
Guide
. For more information about the
trill evb-support
command, see
TRILL Command Reference
.

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.
