Features
The supported features and specifications for the Cisco Catalyst Switch Modules 3110G and 3110X are:
Ports
z
3110G: Four external RJ-45 1000BASE-T connectors for making 10/100/1000 Mbps connections
z
to a backbone, end stations, and servers.
3110X: One external 10 Gb Ethernet Module slot for forming 10Gb uplinks to backbone switches
z
or routers. This module slot operates at full-duplex and uses hot-swappable Cisco X2 transceiver
modules. The transceiver module is not included and must be ordered from a Cisco Systems
reseller as listed in Table 3.
Two external high-speed StackWise Plus ports for switch module stacking to support Virtual
z
Blade Switch (VBS) technology. Each 3110G switch module ships with one 1-meter StackWise
Plus cable. Other cables are available for order from Cisco Systems resellers as listed in Table 2.
USB-style serial port. This is the Cisco console port, and offers an out-of-band management path
z
if desired. A USB-to-DB-9 cable is used to connect the switch module to a PC. This cable is
shipped with the switch.
14 internal full-duplex Gigabit ports, one connected to each of the blade servers in the
z
BladeCenter unit.
One internal full-duplex 100 Mbps port connected to the management module.
z
Performance features
z
3110G: Auto-sensing of speed on the 10/100/1000 ports and auto-negotiation of duplex mode on
z
the ports for optimizing bandwidth.
3110X: Fixed 10 Gbps speed on external 10 Gb Ethernet port for maximum uplink bandwidth.
z
Up to 64 Gbps of throughput in a switch stack.
z
Gigabit EtherChannel (3110G) or 10 Gb EtherChannel (3110X) for enhanced fault tolerance and
z
to provide up to 8 Gbps (3110G) or 80 Gbps (3110X) of bandwidth between switches, routers,
and servers.
Support for standard frames with sizes from 64 to 1530 bytes and jumbo frames with a maximum
z
size of 9216.
Forwarding of Layer 2 frames and Layer 3 packets at 1 Gbps line rate across switches in stack.
z
Per-port broadcast-storm control for preventing a faulty end station from degrading overall system
z
performance with broadcast storms.
Port Aggregation Protocol (PAgP) and Link Aggregation Control Protocol (LACP) for automatic
z
creation of EtherChannel links.
