Brocade Communications Systems 53-1002163-02 manual Configuring FCoE priority bits

LLDP configuration and management 9

To advertise the optional LLDP TLVs, perform the following steps from privileged EXEC mode.

1.Enter the configure terminal command to access global configuration mode.

2.Enter LLDP configuration mode.

switch(config)#protocol lldp

3. Advertise the optional LLDP TLVs.

switch(conf-lldp)#advertise optional-tlv management-address port-description system-capabilities system-name system-description

Configuring the advertisement of LLDP DCBX-related TLVs

NOTE

By default, the dcbx-tlv is advertised; the dot1-tlv, dot3-tlv, dcbx-fcoe-app-tlv, and dcbx-fcoe-logical-link-tlv are not advertised.

To configure the LLDP DCBX-related TLVs to be advertised, perform the following steps from privileged EXEC mode.

1.Enter the configure terminal command to access global configuration mode.

2.Enter LLDP configuration mode.

switch(config)#protocol lldp

3. Advertise the LLDP DCBX-related TLVs using these commands:

•

•

•

•

•

switch(conf-lldp)#advertise dcbx-fcoe-app-tlv switch(conf-lldp)#advertise dcbx-fcoe-logical-link-tlv switch(conf-lldp)#advertise dcbx-tlv switch(conf-lldp)#advertise dot1-tlv switch(conf-lldp)#advertise dot3-tlv

Configuring FCoE priority bits

The FCoE priority bit setting is a bitmap setting where each bit position stands for a priority. When you set a bit for a particular priority, that priority setting is applied to the FCoE traffic (that is, the incoming FCoE traffic will have that priority). The default value is 0.

NOTE

FCoE traffic is only supported on the priority level that also has flow control enabled. This means that the final advertised FCoE priority consists of the configured FCoE priority setting and the per-priority flow control setting.

Even though setting multiple bits is allowed (exercising the full range of values), it doesn't make sense to set more than one bit, because adapters don't support multiple priorities for FCoE.

To configure the FCoE priority bits, perform the following steps from privileged EXEC mode.

1.Enter the configure terminal command to access global configuration mode.

2.Enter LLDP configuration mode.

switch(config)#protocol lldp

3. Configure the FCoE priority bits.

switch(conf-lldp)#lldp fcoe-priority-bits 3
