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 Fabric Engine and 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.
