Configure an I-SID offset value, and globally enable I-SID offset for the Endpoint Tracking feature. The I-SID offset value is used to calculate an I-SID value for a switched UNI if no I-SID value is provided by the RADIUS server. In that case, the I-SID value is calculated as follows: I-SID = VLAN ID + configured I-SID offset value.
default endpoint-tracking auto-isid-offset
endpoint-tracking auto-isid-offset <0-15995903>
endpoint-tracking auto-isid-offset enable
no endpoint-tracking auto-isid-offset enable
The default status is disabled, and the default I-SID offset value is 15990000.
Global Configuration
This command does not apply to all hardware platforms. For more information about feature support, see VOSS Feature Support Matrix.
Configure the I-SID offset value first, and then enable I-SID offset globally on the switch.
If you have previously enabled Endpoint Tracking globally and want to change the currently configured I-SID offset value, you must disable Endpoint Tracking globally, change the I-SID value, and then re-enable Endpoint Tracking globally.
