lldp tlv-select dcbxp-appln fcoe
Enables FCoE application TLV for an interface.
Syntax
lldp tlv-select dcbxp-appln fcoe
Parameter None
Default Enabled
Command Mode INTERFACE
Usage
Information
The default priority value advertised in FCoE application TLV is 3. If the PFC configuration in an interface
matches 3, then the FCoE application TLV is advertised as 3. Otherwise, FCoE application TLV is not
advertised.
When you configure the application priority using fcoe priority-bits command, the configured
value is advertised in the TLV, which is not dependent on PFC configuration.
The no version of this command disables the FCoE application TLV.
Example
OS10(conf-if-eth1/1/1)# lldp tlv-select dcbx-appln fcoe
Supported
Releases

re-balance fc npg sessions vfabric
Rebalances both FCoE and FC sessions across FC uplinks.
Syntax
re-balance fc npg sessions vfabric vfabric-id [dry-run][brief]
Parameters None
Defaults Not configured
Command Mode EXEC
Usage
Information
Triggers the load-balancing mechanism to redistribute the sessions across the FC uplinks. The dry-run
option displays the current state of the system, sessions that would be cleared, and the system state
after the load balancing is done without actually doing it. You can use the brief option (both in dry
run and actual run) to view only the session redistribution information. You can use the fcoe delay
fcf-adv configuration command to load balance the system during a switch reload. If the system is
unbalanced after the reload and after configuring the fcoe delay fcf-adv command, then use the
rebalance command to balance the sessions. This command is supported in the NPG mode.
NOTE: Dell Technologies recommends that you do not use this command in an NPG cascading
topology.
The fields and their corresponding descriptions that are displayed in this command are as follows:
● Uplink Intf—The name of the FC uplink interface.
● FLOGI—Number of Fabric Login Sessions in the FC uplink interface.
● FDISC—Number of Fabric Discovery Sessions in the FC uplink interface.
● Load—Total number of sessions (FLOGI and FDISC) in the FC uplink interface.
● Speed—Link speed of the FC uplink interface.
● Excess Load—Excess load is the absolute (Current load on the link - ((Minimum load per 8G
speed in current state) * port-speed/8G)). It captures the level to which the corresponding link is
oversubscribed when compared to other FC upstream links in the system.
● Node WWPN—World-Wide Port Name, which is used for the Fabric Login request of the Server that
is connected to the OS10 switch. It can be an FCoE server or an FC server.
●
From Uplink Intf—Interface name of the FC uplink from which the sessions from the server are
redistributed.
● To Uplink Intf—Interface name of the FC uplink to which the sessions are mapped when the server
logs back in.
● No. of sessions—Count of redistributed sessions.
