Configuring lldp, Specifying a default vsi manager – H3C Technologies H3C S6800 Series Switches User Manual

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, or both EVB and QinQ on the same interface.
Do not create a service instance for an interface enabled with EVB, and vice versa.
To enable EVB:
Step Command

1.
Enter system view.

2.
Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.

3.
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:

By default, LLDP is enabled on an
interface.
5.
Configure the Nearest

LLDP to operate in TxRx mode.

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.
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.
