5 FC0E configuration tasks FC0E configuration tasks There are several tasks related to FC0E configuration. The following lists the high level tasks in a suggested order: • Quality of Service (QoS) configuration (optional) - If you intend to implement a specific QoS scheme to prioritize data traffic, it is recommended that you finish your QoS configuration before you begin port configuration. QoS values are referenced when you configure ports.
Quality of Service (QoS) configuration 5 Quality of Service (QoS) configuration As a general concept, QoS is a mechanism for classifying and scheduling data traffic based on priority settings. QoS can be used to control traffic congestion, allocate bandwidth, and carry data traffic with different characteristics over a common interface. Two configuration options are available: • You can create a CEE map.
5 Quality of Service (QoS) configuration 4. Select Add. The CEE Map Configuration dialog box is displayed (Figure 13). FIGURE 13 CEE Map Configuration dialog box 5. Type a name for the CEE map in the Name field. 6. Type a precedence value in the Precedence field. The value is specified as a number. The allowable range is 0 to 100. The default is 1. The precedence value controls QoS scheduling policies.
Quality of Service (QoS) configuration 5 An entry is added to the Priority Group table (Figure 14). When you add an entry, a PGID is automatically assigned. The PGID is an integer from 0 to 7. The first added entry is given a PGID of 0, and the PGID increments by one for each additional added entry until a PGID of 7 is reached. FIGURE 14 Adding a Priority Group 8. Edit the Bandwidth entry to indicate the desired percentage of total bandwidth. 9.
5 Quality of Service (QoS) configuration The Traffic Class Map Configuration dialog box is displayed (Figure 15). This dialog box has the same structure as the Priority Group Map in the CEE Configuration dialog box (Figure 14). The default CoS-to-traffic class structure is based on IEEE 802.1Q recommendations, as in the default Priority Group Map shown in Figure 14. FIGURE 15 Traffic Class Map Configuration dialog box 5. Type a name for the traffic class map in the Name field. 6.
LLDP-DCBX configuration 5 LLDP-DCBX configuration Link Layer Discovery Protocol (LLDP) is a IEEE standard for collecting and distributing device information. Data Center Bridging Exchange (DCBX) extends LLDP by providing a protocol for discovering, initializing, and managing CEE-compliant devices. There are two configuration procedures: • Configuring global LLDP characteristics. • Configuring an LLDP profile.
5 LLDP-DCBX configuration 7. In the Hello field, enter a time value in seconds. The Hello value sets the interval between hello bridge protocol data units sent by the root switch configuration messages. The range is 4 to 180 seconds. The default is 30 seconds. 8. In the Multiplier field, set the number of consecutive misses allowed before LLDP considers the interface to be down. The range is 1 to 10. The default is 4.The multiplier is related to the Hello time interval.
LLDP-DCBX configuration 5 4. Click Add. The LLDP Configuration dialog box is displayed (Figure 18). FIGURE 18 LLDP dialog box 5. Type a name for the configuration in the Name field. 6. Optionally, add a description in the Description field. 7. Choose the Mode. For Mode, the choices are tx (transmit), rx, (receive) or Both. The default is Both. 8. In the Hello field, enter a time value in seconds.
5 LLDP-DCBX configuration - Advertise dot1-tlv - Advertises to any attached device to send IEEE 802.1 LLDP type, length, and values. - Advertise dot3-tlv - Advertises to any attached device to send IEEE 802.3 LLDP type, length, and values. - Advertise dcbx-tlv - Advertises to any attached device to send DCBX protocol to send LLDP type, length, and values.

Static mode does not use Link Aggregation Control Protocol (LACP) to negotiate and manage link aggregation. Link participation in the LAG is determined by the link’s operational status and administrative state. Dynamic mode uses LACP. LACP allows partner systems to examine the attributes of the links that connect them and dynamically form a LAG.
Configuring VLANs 5 Configuring VLANs The Virtual LAN (VLAN) capability allows multiple virtual LANs within a single physical LAN infrastructure. The physical interface must be configured as L2 prior to configuring a VLAN, either as in individual interface, or as a LAG. Before you start the VLAN configuration procedure, you need to know which interfaces or LAGs you want to associate with each VLAN. 1. Select the CEE tab on the Switch Administration panel. 2. Select the VLAN tab (Figure 23).
