Dell PowerSwitch S5212F-ON OS10 Enterprise Edition User Guide Release 10.4.3.0 - Page 363

Parameters Default Usage Information Command Mode None Not configured. The no version of this command re-enables STP and applies the currently configured spanning-tree settings. CONFIGURATION INTERFACE Example OS10(config)# interface ethernet 1/1/4 OS10(config-if-eth1/1/4)# spanning-tree disable Supported Releases 10.3.0E or later spanning-tree guard Enables or disables loop guard or root guard on an interface. Syntax Parameters spanning-tree guard {loop | root | none} • loop - Enables loop guard on an interface. • root - Enables root guard on an interface. • none - Sets the guard mode to none. Default Usage Information Command Mode Example Not configured Root guard and loop guard configurations are mutually exclusive. Configuring one overwrites the other from the active configuration. INTERFACE OS10(conf-if-eth1/1/4)# spanning-tree guard root Supported Releases 10.2.0E or later spanning-tree link-type Sets the spanning-tree link type for faster convergence. Syntax spanning-tree link-type {auto | point-to-point | shared} Parameters • auto - Enter the keyword to sets the link type based on the duplex setting of the interface. • point-to-point-Specifies that the interface is a point-to-point or full-duplex link. • shared-Specifies that the interface is a half-duplex medium. Default Command Mode Usage Information Auto INTERFACE As specified in IEEE 802.1w, OS10 assumes a port that runs in full duplex mode as a point-to-point link. A point-topoint link transitions to forwarding state faster. By default, OS10 derives the link type of a port from the duplex mode. You can override the duplex mode using the spanning-tree link-type command. Layer 2 363
