For a complete listing of all commands related to object tracking, refer to the Dell Networking OS
Command Line Interface Reference Guide .
Tracking a Layer 2 Interface
You can create an object that tracks the line-protocol state of a Layer 2 interface and monitors its
operational status (UP or DOWN).
You can track the status of any of the following Layer 2 interfaces:
• 1 Gigabit Ethernet: Enter
gigabitethernet slot/port
in the
track interface interface
command (refer to Step 1).
• 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, from 1 to 128.
– For the E-Series, from 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
A line-protocol object only tracks the link-level (UP/DOWN) status of a specified interface. When the link-
level status goes down, the tracked object status is considered to be DOWN; if the link-level status is up,
the tracked object status is considered to be UP.
To remove object tracking on a Layer 2 interface, use the
no track object-id
command.
To configure object tracking on the status of a Layer 2 interface, use the following commands.
1. Configure object tracking on the line-protocol state of a Layer 2 interface.
CONFIGURATION mode
track object-id interface interface line-protocol
Valid object IDs are from 1 to 65535.
2. (Optional) Configure the time delay used before communicating a change in the status of a tracked
interface.
OBJECT TRACKING mode
delay {[up seconds ] [down seconds ]}
Valid delay times are from 0 to 180 seconds.
The default is 0 .
3. (Optional) Identify the tracked object with a text description.
OBJECT TRACKING mode
description text
The text string can be up to 80 characters.
4. (Optional) Display the tracking configuration and the tracked object’s status.
