Static IP routing for manually building a routing table of network path information.
Equal-cost routing for load-balancing and redundancy.
Internet Control Message Protocol (ICMP) and ICMP Router Discovery Protocol (IRDP) for using
router advertisement and router solicitation messages to discover the addresses of routers on
directly-attached subnets.
DHCP relay for forwarding UDP broadcasts, including IP address requests, from DHCP clients.
IPv6 support
IPv6 host support (IPv6 unicast addressing, IPv6 traffic processing, IPv6 applications support
including DNS, ping, traceroute, telnet, ftp, tftp, http, and ssh). IPv6 traffic forwarding is not
supported. IPv6 host support is incorporated into the IP Base software feature set that comes
standard with this switch module.
IPv4 and IPv6 coexistence. The switch module supports dual IPv4 and IPv6 protocol stacks to
provide seamless step-by-step migration to an IPv6 environment.
Note: Unlike the Cisco Catalyst 3110 family of switches, the Cisco Catalyst 3012 module only
supports IPv6 host functions, and does not support IPv6 routing (IPv6 traffic forwarding, IPv6 static
routes, and OSPF, RIP, or EIGRP for IPv6), and IPv6 ACLs.
IP unicast reverse path forwarding (unicast RPF) for confirming source packet IP addresses.
Monitoring features:
Switch LEDs that provide visual port, switch, and stack-level status.
SPAN/RSPAN support for local and remote monitoring of the network.
Four groups (history, statistics, alarms, and events) of embedded remote monitoring (RMON) agents
for network monitoring and traffic analysis.
MAC address notification for tracking the MAC addresses that the switch has learned or removed.
Syslog facility for logging system messages about authentication or authorization errors, resource
issues, and time out events.
Layer 2 trace route 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.
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.
