Configure DCBX operation at the INTERFACE level on a switch or globally on the switch. To verify the
DCBX configuration on a port, use the show interface dcbx detail command.
debug dcbx
Enable DCBX debugging.
Syntax
debug dcbx {all | auto-detect-timer | config-exchng | fail | mgmt |
resource | sem | tlv}
To disable DCBX debugging, use the no debug dcbx command.
Parameters
{all | auto-
detect-timer |
config-exchng |
fail | mgmt |
resource | sem |
tlv}
Enter the type of debugging, where:
● all: enables all DCBX debugging operations.
● auto-detect-timer: enables traces for DCBX auto-detect timers.
● config-exchng: enables traces for DCBX configuration exchanges.
● fail: enables traces for DCBX failures.
● mgmt: enables traces for DCBX management frames.
● resource: enables traces for DCBX system resource frames.
● sem: enables traces for the DCBX state machine.
● tlv: enables traces for DCBX TLVs.

Version Description
9.4(0.0) Supported on the FN I/O Aggregator.
9.3(0.0) Introduced on the FC Flex IO module installed in the M I/O Aggregator.
fc-map
In an FCoE map, configure the FCoE mapped address prefix (FC-MAP) value which is used to identify FCoE traffic transmitted
on the FCoE VLAN for the specified fabric.
Syntax
fc—map fc-map-value
Parameters
fc-map-value Enter the unique MAC address prefix used by a SAN fabric.
The range of FC-MAP values is from 0EFC00 to 0EFCFF.
Defaults None

Version Description
9.6(0.0) Supported on the FN 2210S Aggregator.
9.3(0.0) Introduced on the M I/O Aggregator and MXL 10/40GbE Switch with the FC Flex
IO module.
Usage
Information
The FC-MAP value you enter must match the FC-MAP value used by an FC switch or FCoE forwarder
(FCF) in the fabric. An FCF switch accepts only FCoE traffic that uses the correct FC-MAP value.
