Configuring Static Routing Support
Switches that are running the IP services feature set with Cisco IOS release 12.2(46)SE or later support
enhanced object tracking static routing. Static routing support using enhanced object tracking provides
the ability for the switch to use ICMP pings to identify when a preconfigured static route or a DHCP
route goes down. When tracking is enabled, the system tracks the state of the route and informs the client
when that state changes. Static route object tracking uses Cisco IP SLAs to generate ICMP pings to
monitor the state of the connection to the primary gateway.
For more information about Cisco IP SLAs support on the switch, see Chapter 1, “Configuring Cisco
IOS IP SLAs Operations.”

You use this process to configure static route object tracking:
Step 1 Configure a primary interface for static routing or for DHCP.
Step 2
Configure an IP SLAs agent to ping an IP address using a primary interface and a track object to monitor
the state of the agent.
Step 3 Configure a default static default route using a secondary interface. This route is used only if the primary
route is removed.
Configuring a Primary Interface
Beginning in privileged EXEC mode, follow these steps to configure a primary interface for static
routing:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2 interface interface-id Select a primary or secondary interface and enter interface
configuration mode.
Step 3 description string Add a description to the interface.
Step 4 ip address ip-address mask [ secondary] Set the primary or secondary IP address for the interface.
Step 5
exit Return to global configuration mode.
