Configuring Lldp Trapping - HP 5820X series Configuration Manual

The device uses PFC parameters to negotiate with the server adapter, and to enable PFC for specific
802.1p priorities on the server adapter.
To configure PFC parameters:
To do...
1. Enter system view
2. Enter Layer 2 Ethernet interface
view
3. Enable the Ethernet interface to
automatically negotiate with its
peer to decide whether to enable
PFC
4. Enable PFC for specific 802.1p
priorities
5. Configure the switch to use the
802.1p priority in incoming
packets for priority mapping
To advertise the PFC data, you must enable PFC in auto-negotiation mode.
HP recommends you to enable PFC only for the 802.1p priority of the FCoE traffic. Packet loss might
occur because of congestion, if you enable PFC for multiple 802.1p priorities.
For more information about the priority-flow-control and priority-flow-control no-drop dot1p commands,
see the Layer 2—LAN Switching Command Reference.
For more information about the 802.1p priority, priority trust mode, and port priority, see the ACL and
QoS Configuration Guide. For more information about the qos trust dot1p command, see the ACL and
QoS Command Reference.

Configuring LLDP trapping

LLDP trapping notifies the NMS of events such as newly-detected neighboring devices and link
malfunctions.
To prevent excessive LLDP traps from being sent when topology is unstable, you can set a minimum trap
sending interval for LLDP.
Use the command...
system-view
interface interface-type interface-
number
priority-flow-control auto
priority-flow-control no-drop dot1p
dot1p-list
qos trust dot1p

Remarks
—
—
Required.
Disabled by default.
Required.
By default, all packets with
an 802.1p priority are
discarded when network
congestion occurs.
Required.
By default, the switch does
not use the priority in
incoming packets, but the
priority of the receiving port
as the 802.1p priority of the
incoming packets.
