Cisco Catalyst Blade Switch 3130 and 3032 for Dell Software Configuration Guide
OL-13270-03
Chapter 1 Overview
Features
• Secure Copy Protocol (SCP) feature to provide a secure and authenticated method for copying
switch configuration or switch image files (requires the cryptographic universal software image)
• Wired location service that sends location and attachment tracking information for connected
devices to a Cisco Mobility Services Engine (MSE)
• LLDP-MED network-policy profile time, length, value (TLV) for creating a profile for voice and
voice-signalling by specifying the values for VLAN, class of service (CoS), differentiated services
code point (DSCP), and tagging mode CPU utilization threshold trap to monitor CPU utilization
• The HTTP client in Cisco IOS supports can send requests to both IPv4 and IPv6 HTTP servers, and
the HTTP server in Cisco IOS can service HTTP requests from both IPv4 and IPv6 HTTP clients.
• SNMP can be configured over IPv6 transport so that an IPv6 host can send SNMP queries and
receive SNMP notifications from a device running IPv6.
• IPv6 supports stateless autoconfiguration to manage link, subnet, and site addressing changes, such
as management of host and mobile IP addresses.
Note For additional descriptions of the management interfaces, see the “Network Configuration Examples”
section on page 1-17 .
Availability and Redundancy Features
These are the availability and redundancy features:
• HSRP for command switch and Layer 3 router redundancy
• Automatic stack master re-election (failover support) for replacing stack masters that become
unavailable (only stacking-capable switches)
The newly elected stack master begins accepting Layer 2 traffic in less than 1 second and Layer 3
traffic between 3 to 5 seconds.
• Cross-stack EtherChannel for providing redundant links across the switch stack (only
stacking-capable switches)
• UniDirectional Link Detection (UDLD) and aggressive UDLD for detecting and disabling
unidirectional links on fiber-optic interfaces caused by incorrect fiber-optic wiring or port faults
• IEEE 802.1D Spanning Tree Protocol (STP) for redundant backbone connections and loop-free
networks. STP has these features:
– Up to 128 spanning-tree instances supported
– Per-VLAN spanning-tree plus (PVST+) for load-balancing across VLANs
– Rapid PVST+ for load-balancing across VLANs and providing rapid convergence of
spanning-tree instances
– UplinkFast, cross-stack UplinkFast (only stacking-capable switches), and BackboneFast for
fast convergence after a spanning-tree topology change and for achieving load-balancing
between redundant uplinks, including Gigabit uplinks and cross-stack Gigabit uplinks (only
stacking-capable switches)
• IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) for grouping VLANs into a spanning-tree
instance and for providing multiple forwarding paths for data traffic and load-balancing and rapid
per-VLAN Spanning-Tree plus (rapid-PVST+) based on the IEEE 802.1w Rapid Spanning Tree
Protocol (RSTP) for rapid convergence of the spanning tree by immediately changing root and
designated ports to the forwarding state
