Release Information
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Statement updated in Junos OS Release 9.4 for EX Series switches to add VSTP support.
Description
For Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), VLAN Spanning Tree Protocol (VSTP), or Multiple Spanning Tree Protocol (MSTP), configure the link mode to identify point-to-point links.
Default
For a full-duplex link, the default link mode is point-to-point. For a half-duplex link, the default link mode is shared.
 | Note: For EX4300 switches, the interfaces operate in full-duplex mode only. |
Options
mode—Link mode:
- point-to-point—Link is point to point.
- shared—Link is shared media.
Required Privilege Level
routing—To view this statement in the
configuration.
routing-control—To add this statement
to the configuration.
