Configuring App Parameters - HP FlexFabric 12900 Series Configuration Manual

After the configuration, LLDP frames sent by the local port carry information about the configured
•
DCBX version. The local port and peer port do not negotiate the DCBX version.
If the DCBX version is autonegotiated, the version IEEE Std 802.1Qaz-201 1 is preferably negotiated.
•
To configure the DCBX version:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view.
3. Configure the DCBX
version.

Configuring APP parameters

The device negotiates with the server adapter by using the APP parameters to achieve the following
purposes:
• Control the 802.1p priority values of the protocol packets that the server adapter sends.
Identify traffic based on the 802.1p priority values.
•
For example, the device can use the APP parameters to negotiate with the server adapter to set 802.1p
priority 3 for all FCoE and FIP frames. When the negotiation succeeds, all FCoE and FIP frames that the
server adapter sends to the device carry the 802.1p priority 3.
Configuration restrictions and guidelines
When you configure APP parameters, follow these restrictions and guidelines:
An Ethernet frame header ACL identifies application protocol packets by protocol number.
•
An IPv4 advanced ACL identifies application protocol packets by IP port number.
•
• DCBX Rev 1.00 identifies application protocol packets only by protocol number and advertises TLVs
with protocol number 0x8906 (FCoE) only.
DCBX Rev 1.01 has the following attributes:
•
Supports identifying application protocol packets by both protocol number and IP port number.
Does not restrict the protocol number or IP port number for advertising TLVs.
Can advertise up to 77 TLVs according to the remaining length of the current packet.
