4 Remote Inhibit

The Remote Inhibit functionality supports Inhibit/Uninhibit of Links from far end. The feature is mainly used for maintenance purpose. The following points describes the work flow:

• While this feature is enabled, traffic does not route through the inhibit link.
• When the inhibit message (LIN) is received on vSTP, the link becomes unavailable on MTP3 layer.
• There is no link state change on MTP2 layer.
• vSTP will send LIA as acknowledgement of LIN message confirming link is inhibit.
• When uninhibit message (LUN) is received on vSTP, the link becomes available on MTP3 layer.
• vSTP will send LUA as acknowledgement of LUN message confirming link is uninhibit and the traffic routes through the same link.

Note:

vSTP does not support Local Inihibit of Links. Only the handling of remote inhibit procedures is supported.
