ADVANCED QoS
The Cisco Catalyst Blade Switch 3030 offers superior multilayer, granular QoS features to avoid congestion and help ensure that network traffic is
properly classified and prioritized. The Cisco Catalyst Blade Switch 3030 can classify, police, mark, queue, and schedule incoming packets and can
queue and schedule packets at egress. Packet classification allows the network elements to discriminate between various traffic flows and to enforce
policies based on Layer 2 and Layer 3 QoS fields.
To implement QoS, the Cisco Catalyst Blade Switch 3030 first identifies traffic flows or packet groups and classifies or reclassifies these groups
using the Differentiated Services Code Point (DSCP) field or the 802.1p class-of-service (CoS) field. Classification can be based on criteria as
specific as the source/destination IP address, the source/destination MAC address, or the Layer 4 TCP/UDP port. At the ingress, the Cisco Catalyst
Blade Switch 3030 will also police to determine whether a packet is in or out of profile, mark to change the classification label, pass through, or drop
out of profile packets, queue packets based on classification, and service based on configured weights. Control-plane and data-plane ACLs are
supported on all ports to help ensure proper treatment on a per-packet basis. The Cisco Catalyst Blade Switch 3030 supports four egress queues per
port, which allows the network administrator to be discriminating and specific in assigning priorities for the various applications in the server farm.
At egress, the switch performs scheduling and congestion control. Scheduling is a process that determines the order in which the queues are
processed. The Cisco Catalyst Blade Switch 3030 supports Shaped Round Robin (SRR) and strict priority queuing. The SRR queuing algorithm
helps to ensure differential prioritization.
MANAGEMENT
The Catalyst Blade Switch 3030 comes with an embedded GUI device manager that simplifies initial configuration of a switch. Users now have the
option to set up the switch through a Web browser. Users familiar with the Cisco command-line interface (CLI) can also use the CLI to do initial
configuration and setup. Hence, users do not need any retraining.
Cisco Catalyst Blade Switch 3030 provides for extensive management using SNMP network management platforms such as CiscoWorks for
Switched Internetworks. Managed with CiscoWorks, Cisco Catalyst switches can be configured and managed to deliver end-to-end device, VLAN,
traffic, and policy management. As part of CiscoWorks, the Web-based Cisco Resource Manager Essentials (RME) offers automated inventory
collection, software deployment, easy tracking of network changes, views into device availability, and quick isolation of error conditions.

Features and Benefits
Ease of Use and
Ease of Deployment
•
Device manager simplifies initial configuration using a Web browser.
•
DHCP autoconfiguration of multiple switches through a boot server eases switch deployment.
•
Autosensing detects the speed of the upstream switch and automatically configures each 10/100/1000 uplink port for 10-
Mbps, 100-Mbps, or 1000-Mbps operation, easing switch deployment in mixed 10BASE-T, 100BASE-T, and 1000BASE-
T environments.
•
Autonegotiating on 10/100/1000 ports automatically selects half-duplex or full-duplex transmission mode to optimize
bandwidth.
•
Dynamic Trunking Protocol (DTP) enables dynamic trunk configuration across all switch ports.
•
Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel
®
groups or Gigabit EtherChannel
groups to link to the upstream switch/router or server blades.
•
Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with upstream switches that
