Giga-Phy-Mode - Supermicro SSE-G2252 User Manual

giga-phy-mode

This command forces two connected ports into a master/slave configuration to enable
1000BASE-T full duplex for Gigabit ports. Use the no form to restore the default mode.
Syntax
giga-phy-mode mode
no giga-phy-mode
mode
master - Sets the selected port as master.
slave - Sets the selected port as slave.
Default Setting
master

Interface Configuration (Ethernet - Range: 1-52)
Command Usage
• The 1000BASE-T standard does not support forced mode. Auto-negotiation should
always be used to establish a connection over any 1000BASE-T port or trunk. If not
used, the success of the link process cannot be guaranteed when connecting to
other types of switches. However, this switch does provide a means of forcing a link
to operate at 1000 Mbps, full-duplex using the giga-phy-mode command.
• To force 1000full operation requires the ports at both ends of a link to establish their
role in the connection process as a master or slave. Before using this feature,
auto-negotiation must first be disabled, and the Speed/Duplex attribute set to
1000full. Then select compatible Giga PHY modes at both ends of the link.
• If auto-negotiation is enabled at the far end of a link, and disabled on the local end,
a link should eventually be established regardless of the selected giga-phy mode.
Example
This forces the switch port to master mode on port 24.
Console(config)#interface ethernet 1/50
Console(config-if)#no negotiation
Console(config-if)#speed-duplex 1000full
Console(config-if)#giga-phy-mode master
