CEE switch support
3
Enabling or disabling CEE port
The CEE port is represented by Brocade_EthernetPort. The class Brocade_EthernetPort in
BrocadePartitioning.mof is updated with the following content:
• A new extrinsic method RequestStateChange is inherited from the standard CIM class
CIM_EnabledLogicalElement. This method should be used to disable or enable the CEE port.
• A new property RequestedState is inherited from the standard CIM class
CIM_EnabledLogicalElement. Knowledge of the last RequestedState is not supported for the
CEE port, thus the property will always have the value 12 (Not Applicable).
Setting interface mode of CEE port
Setting the interface mode of a CEE port is done by setting the Interface Mode property of the
Brocade_LANEndpoint associated to the CEE port. The class Brocade_LANEndPoint in
BrocadeEthernet.mof is updated with a new property InterfaceMode, which is a proprietary
property that indicates whether the CEE port is in Layer 2, Layer 3, or none mode. The property is
writable and can be set using the setInstance intrinsic operation. Layer 3 mode is not supported.
Setting Layer 2 mode of CEE port
Setting the Layer 2 mode of a CEE port is done by setting the OperationalEndpointMode property of
the Brocade_LANEndpoint associated to the CEE port. The class Brocade_LANEndpoint in
BrocadeEthernet.mof is updated with a new property OperationalEndpointMode, which is a
proprietary property that indicates whether the CEE port is in access, trunk or converged Layer 2
mode of operation. The property is writable and can be set using the setInstance intrinsic
operation.
BrocadeEthernet.mof is updated to include support for this new property.
Enabling or disabling LLDP-DCBX on Ethernet switch and CEE port
With Layer 2 networks expanding dramatically, it is difficult for a network administrator to statically
monitor and configure each device in the network. Using Link Layer Discovery Protocol (LLDP), the
network devices such as routers and switches advertise information about themselves to other
network devices and store the information they discover.
Data Center Bridging Exchange (DCBX) is used to exchange CEE-related parameters with neighbors
to achieve more efficient scheduling and a priority-based flow control for link traffic. DCBX is built
on the LLDP infrastructure and uses LLDP to exchange parameters between two link peers. DCBX
is on by default.
Brocade Network Advisor SMI Agent supports enabling or disabling the default LLDP-DCBX at the
switch and port levels. Users can enable or disable the global configuration at the switch level. User
can also enable or disable the specific LLDP configuration currently applied at the port level.
There is no support for defining any new LLDP profiles through Brocade Network Advisor SMI Agent.
Saving the running configuration to the startup configuration on the CEE switch
This feature allows you to save all the CEE configuration changes made after startup so that they
are persisted across reboots. The class Brocade_EthernetSwitch in BrocadeEthernet.mof is
updated with a new extrinsic method ConfigSaveRunningToStartup. This method saves the CEE
changes to startup configuration on the switch. The changes are visible even after a reboot.
