Catalyst Switch Module 3012
The Catalyst Switch Module 3012 is an 18-Gigabit Ethernet port, Layer 3 switch module. Up to 14 of
the Gigabit Ethernet ports are internal 1000BASE-X downlink ports that connect to the blade
enclosure. The other four Gigabit Ethernet ports are external uplink ports that provide connections to
other switches or routers. Figure 3 shows the switch module, and Table 2 describes the switch module
ports.

more information about internal port numbering.
Internal Gigabit Ethernet 1000BASE-X downlink ports that connect to the
blade enclosure.
Ports 15 to 18
(Switch module 3110G) External 10/100/1000BASE-T copper Gigabit Ethernet uplink ports that
support auto-MDIX and autonegotiation.
Port 1 (X2)
(Switch module 3110X) External 10-Gigabit Ethernet module slot for use with Cisco X2
transceiver modules.
Internal 100BASE-T
Ethernet port The Ethernet management port (Fa0) is used only for switch module
management traffic, not for data traffic. It is connected to the aMM
through the blade enclosure backplane connector. Traffic to and from this
port is isolated from the switch ports. This port only supports
autonegotiation with 100 Mb/s and full-duplex mode.
StackWise Plus ports Stacking cable ports.
Console port Switch module management port (USB-to-DB-9connector).
