Synopsis: A 32-bit signed integer between 1 and 16
The Multiple Spanning Tree Protocol (MSTP) Instance ID.
Synopsis: { { sm, lm1, lm2, lm3, lm4, lm5, lm6, swport, eth, serport, celport, wlanport }
{ trnk } }
The slot of the module that contains this port.
Synopsis: A 32-bit signed integer between 1 and 16
The port number as seen on the front plate silkscreen of the module.
Synopsis: { disabled, blocking, listening, learning, forwarding, linkDown, discarding }
The status of this interface in the spanning tree:
• Disabled: The Spanning Tree Protocol (STP) is disabled on this port.
• Link Down: STP is enabled on this port but the link is down.
• Discarding: The link is not used in the STP topology but is standing by.
• Learning: The port is learning MAC addresses in order to prevent flooding when it begins
forwarding traffic.
• Forwarding: The port is forwarding traffic.
This parameter is mandatory.
Synopsis: { ----, root, designated, alternate, backup, master }
The role of this port in the spanning tree:
