The GM-4Xi module has four GBIC-based Gigabit Ethernet ports. All Gigabit Ethernet ports on this
module use standard GBIC connectors and support 1000BASE-SX, 1000BASE-LX, and 1000BASE-LX70.
The default configuration of the GM-4Xi module is as follows. All ports:
• Are added to the default VLAN as untagged.
• Inherit the properties of the default VLAN (protocol type, VLANid, and so forth).
• Operate in autonegotiation mode.
