Working of the Management Port Media Converter
QSFP EEPROM content is accessed to detect this special media converter and based on this identification
performed, a new optic type is used to differentiate this optic type from the other optics. This new optic
type is displayed in the appropriate show commands and for enabling other functionalities. EEPROM
contents are displayed in the output of the ‘show interface transceiver’ command. The optic functions in
the same manner as any other fanout QSFP 4x10G cable, with the exception that this optic needs the
speed to be manually configured in the software.
Because of the optic type that is present in the media converter to connect the QSFP port with the PDU
requiring the speed to be configured, you can use the speed command to configure each of the 4 fanout
ports with the required speed of 1G, 100M, or 10M. Because the S6000 platform does not provide the
autonegotiation in SGMII mode, it is required that you configure the speed of the individual 4 fanout ports
based on the peer PDU’s configuration by using the speed command. By default, each port runs at a
speed of 1G during the time of insertion of the optic.
The speed command is available for configuration only when the management optic is inserted in to a
quad-mode interface. Because this optic cannot be used in a non-fanout port, you must ensure that
fanout is enabled to use this optic, similar to how it is enabled for other 4x10G fanout cables. All existing
commands and configuration settings for that port are retained with the additional speed command
setting.
Based on the optic detection and fanout mode configuration, you can use the speed command. This
command is activated for configuration on optic insertion and removed on optic removal. In non-quad
mode, the speed CLI is not enabled (if you did not configure the stack-unit stack-unit port number
portmode quad command). The media converter speed CLI is enabled only on fanout configured ports.
If an optic is inserted in to a non-fanout port, there is no change in the functionality and you must
configure fanout and reload the device to use this optic. When the management (MGMT) optic is
inserted, the default speed is configured and the speed CLI is enabled. When MGMT optic is removed, the
speed CLI is disabled and its related settings are removed from the running configuration.
The following is the portion of the sample output of the show config command when the management
optic is inserted:
FTOS(conf-if-te-2/10)#show config
interface TenGigabitEthernet 2/10
speed 100
no shutdown
The following is the sample output of the show interface command when the management optic is
inserted:
FTOS>show interface tengig 0/0
TenGigabitEthernet 0/0 is up, line protocol is up
Hardware is DellForce10Eth, address is 90:b1:1c:f4:9a:fa
Current address is 90:b1:1c:f4:9a:fa
Pluggable media present, QSFP type is 40GBASE-XXXX
LineSpeed 100 Mbit
The following system log messages are displayed for optic insertion and removal, which are identical to
the messages displayed for other QSFP optics:
On Optic Insertion:
