Tracking a Layer 3 Interface
You can create an object that tracks the routing status of an IPv4 or IPv6 Layer 3 interface. You can track
the routing status of any of the following Layer 3 interfaces:
• 1-Gigabit Ethernet: Enter
gigabitethernet slot/port in the track interface interface command (see Step 1
below).
• 10-Gigabit Ethernet: Enter
tengigabitethernet slot/port.
• Port channel: Enter
port-channel number, where valid port-channel numbers are:
• For the C-Series and S-Series, 1 to 128
• For the E-Series, 1 to 32 (EtherScale) and 1 to 255 (TeraScale and ExaScale)
• SONET: Enter
sonet slot/port.
• VLAN: Enter
vlan vlan-id, where valid VLAN IDs are from 1 to 4094.

Valid object IDs are from 1 to 65535.
CONFIGURATION
2 (Optional) Configure the time delay used
before communicating a change in the
status of a tracked interface.
delay {[up seconds] [down
