Ta b l e 1-1 Cisco Catalyst Blade Switch 3120 for HP Port Descriptions
Port Description
Ports 1 to 16 Internal Gigabit Ethernet 1000BASE-X downlink ports that connect to the
blade enclosure.
Ports 17 to 18 Internal cross-connection ports that you can use to connect to a second switch
in the blade enclosure through a backplane connector. You can configure
these ports by using the Cisco IOS CLI
1
. However, if the blade switches are
stacked, these ports are disabled.
Ports 19 to 22 10-Gigabit Ethernet module slots for use with the Cisco TwinGig Converter
Modules and Cisco X2 transceiver modules.
Ports 23 to 26 External 10/100/1000BASE-T copper Gigabit Ethernet uplink ports that
support auto-MDIX and autonegotiation.
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
Onboard
Administrator 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.
