Cisco Catalyst Blade Switch 3130 for Dell Software Configuration Guide
OL-13270-01
Chapter 1 Overview
Features
• Nonstop forwarding (NSF) awareness to enable the Layer 3 switch to continue forwarding packets
from an NSF-capable neighboring router when the primary route processor (RP) is failing and the
backup RP is taking over, or when the primary RP is manually reloaded for a nondisruptive software
upgrade (requires the IP services feature set)
• NSF-capable routing for OSPF and EIGRP that allows the switch to rebuild routing tables based on
information from NSF-aware and NSF-capable neighbors (only stacking-capable switches)
Monitoring Features
These are the monitoring features:
• Switch LEDs that provide port-, switch-, and stack-level status on stacking-capable switches
• MAC address notification traps and RADIUS accounting for tracking users on a network by storing
the MAC addresses that the switch has learned or removed
• Switched Port Analyzer (SPAN) and Remote SPAN (RSPAN) for traffic monitoring on any port or
VLAN
• SPAN and RSPAN support of Intrusion Detection Systems (IDS) to monitor, repel, and report
network security violations
• Four groups (history, statistics, alarms, and events) of embedded RMON agents for network
monitoring and traffic analysis
• Syslog facility for logging system messages about authentication or authorization errors, resource
issues, and time-out events
• Layer 2 traceroute to identify the physical path that a packet takes from a source device to a
destination device
• Time Domain Reflector (TDR) to diagnose and resolve cabling problems on 10/100 and
10/100/1000 copper Ethernet ports
• SFP module diagnostic management interface to monitor physical or operational status of an SFP
module
• Online diagnostics to test the hardware functionality of the supervisor engine, modules, and switch
while the switch is connected to a live network
• On-board failure logging (OBFL) to collect information about the switch and the power supplies
connected to it
• Enhanced object tracking (EOT) for HSRP to determine the proportion of hosts in a LAN by tracking
the routing table state or to trigger the standby router failover
• IP Service Level Agreements (IP SLAs) support to measure network performance by using active
traffic monitoring
• IP SLAs EOT to use the output from IP SLAs tracking operations triggered by an action such as
latency, jitter, or packet loss for a standby router failover takeover
• Embedded event manager (EEM) for device and system management to monitor key system events
and then act on them though a policy
