Features
The supported features and specifications for the Cisco Catalyst 3012 switch module are:
Ports:
Four external RJ-45 1000BASE-T connectors for making 10/100/1000 Mbps connections to a
backbone, end stations, and servers.
14 internal full-duplex Gigabit ports, one connected to each of the blade servers in the BladeCenter
unit.
USB-style serial port. This is the Cisco console port, and offers a totally out-of-band management
path if desired. A USB-to-DB9 cable is used to connect the switch module to PC. This cable is
shipped with the switch.

corresponding MAC address.
Cisco Discovery Protocol (CDP) Versions 1 and 2 to aid in troubleshooting and reporting on
misconfiguration of ports connecting to other devices supporting CDP.

upgrades from a TFTP server.
Default configuration storage in flash memory to ensure that the switch can be connected to a
network and can forward traffic with minimal user intervention.
In-band monitoring of the switch through the built-in Cisco Device Manager Web-based tool.
In-band management access through up to 16 simultaneous Telnet connections for multiple
command line interface (CLI)-based sessions over the network.

Extensive debugging options to aid in troubleshooting and diagnosing issues.
Support for multiple management interfaces.
Availability and redundancy features:
Hot Standby Routing Protocol (HSRP) for Layer 3 router redundancy.
Link state tracking to mirror the state of the external ports on the internal Ethernet links and to allow
the failover of the processor blade traffic to an operational external link on a separate Cisco Ethernet
switch.
Configurable Unidirectional link detection (UDLD) for detecting and disabling unidirectional links. This
feature prevents a larger network failure in the event that a unidirectional link is detected, thus
reducing downtime in these situations.

networks.
IEEE 802.1s Multiple STP (MSTP) for grouping VLANs into a spanning tree instance, and provided for
multiple forwarding paths for data traffic and load balancing.
IEEE 802.1w Rapid STP (RSTP) for rapid convergence of the spanning tree by immediately
transitioning root and designated ports to the converting state.

Optional spanning tree features available in the PVST+, rapid PVST+, and MSTP modes.
Flex Link Layer 2 interfaces to back up one another as an alternative to STP for basic link
redundancy.

which are reserved by Cisco.
Cisco Inter-Switch Link (ISL) and IEEE 802.1Q trunking protocol on all ports for network moves,
adds, and changes; management and control of broadcast and multicast traffic; and network
security by establishing VLAN groups for high-security users and network resources.
VLAN Query Protocol (VQP) for dynamic VLAN membership.
VLAN Trunking Protocol (VTP) pruning for reducing network traffic by restricting flooded traffic to
links destined for stations receiving the traffic.
Dynamic Trunking Protocol (DTP) for negotiating trunking on a link between two devices and for
negotiating the type of trunking encapsulation (802.1Q) to be used.
Voice VLAN for creating subnets for voice traffic from Cisco IP phones.
VLAN 1 minimization to reduce the risk of spanning tree loops or storms by enabling VLAN 1 to be
disabled on any individual VLAN trunk link. With this feature enabled, no user traffic is sent or
received. The switch CPU continues to send and receive control protocol frames.
Private VLANs to address VLAN scalability issues.
VLAN Flex Link Load Balancing to provide Layer 2 link redundancy without STP.
Support for up to 128 instances of spanning tree per switch or per switch stack.

Quality of Service (QoS) and Class of Service (CoS) features:
Automatic QoS (auto-QoS) to simplify the deployment of existing QoS features by classifying traffic
and configuring egress queues.
Cross-stack QoS for configuring QoS features to all switches in a switch stack rather than on an
individual-switch basis.
Classification
IP Type of Service/Differentiated Services Code Point (IP ToS/DSCP) and IEEE 802.1p CoS
marking priorities on a per-port basis for protecting the performance of mission-critical
applications.
IP ToS/DSCP and IEEE 802.1p CoS marking for flow-based packet classification
(classification based on information in the MAC, IP, and TCP/UDP headers) for highperformance QoS at the network edge, allowing for differentiated service levels for different
types of network traffic and prioritizing mission-critical traffic in the network.
Trusted port states (CoS, DSCP, and IP precedence) within a QoS domain and with a port
bordering another QoS domain.
Trusted boundary for detecting the presence of a Cisco IP Phone, trusting the CoS value
received, and ensuring port security.
Policing
Traffic-shaping policies on the switch port for managing how much of the port bandwidth
should be allocated to a specific traffic flow.
Out-of-profile markdown for packets that exceed bandwidth utilization limits.
Ingress queuing and scheduling
Two configurable ingress queues for user traffic (one queue can be the priority queue).
Weighted tail drop (WTD) as the congestion-avoidance mechanism for managing the queue
lengths and providing drop precedences for different traffic classifications.
Shaped round robin (SRR) as the scheduling service for specifying the rate at which packets
are sent to the stack or internal ring (sharing is the only supported mode on ingress queues).
Egress queues and scheduling
Four egress queues per port.
WTD as the congestion-avoidance mechanism for managing the queue lengths and providing
drop precedences for different traffic classifications.
SRR as the scheduling service for specifying the rate at which packets are dequeued to the
egress interface (shaping or sharing is supported on egress queues).
Automatic quality of service (QoS) voice over IP (VoIP) enhancement for port-based trust of
DSCP and priority queuing for egress traffic.
Egress policing and scheduling of egress queues - four egress queues on all switch ports;
support for strict priority and weighted round-robin (WRR) CoS policies.
Layer 3 features:
HSRP for Layer 3 router redundancy.
IP routing protocols for load balancing and for constructing scalable, routed backbones RIP Versions
1 and 2.
Note: Unlike the Cisco Catalyst 3110 family of switches, the Cisco Catalyst 3012 module does not
support OSPF, BGP, and EIGRP routing protocols, policy-based routing, VPNs, and multicast
routing,
IP routing between VLANs (inter-VLAN routing) for full Layer 3 routing between two or more VLANs,
allowing each VLAN to maintain its own autonomous data-link domain.
