For an IPv4 interface, a routing object only tracks the UP/DOWN status of the specified IPv4 interface
track interface ip-routing
(
• The status of an IPv4 interface is UP only if the Layer 2 status of the interface is UP and the interface
has a valid IP address.
• The Layer 3 status of an IPv4 interface goes DOWN when its Layer 2 status goes down (for a Layer 3
VLAN, all VLAN ports must be down) or the IP address is removed from the routing table.
For an IPv6 interface, a routing object only tracks the UP/DOWN status of the specified IPv6 interface
track interface ipv6-routing
(
• The status of an IPv6 interface is UP only if the Layer 2 status of the interface is UP and the interface
has a valid IPv6 address.
• The Layer 3 status of an IPv6 interface goes DOWN when its Layer 2 status goes down (for a Layer 3
VLAN, all VLAN ports must be down) or the IPv6 address is removed from the routing table.
To configure object tracking on the routing status of a Layer 3 interface, use the following commands. To
remove object tracking on a Layer 3 IPv4/IPv6 interface, enter the
Step Task
1 Configure object tracking on the routing
status of an IPv4 or IPv6 interface.
2 (Optional) Configure the time delay used
before communicating a change in the
status of a tracked interface.
3 (Optional) Identify the tracked object
with a text description.
4 (Optional) Display the tracking
configuration and the tracked object's
status.
