xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch CLI Manual config stp version Purpose Syntax Description Parameters Restrictions Used to globally set the version of STP on the Switch. config stp version [mstp | rstp | stp] This command allows the user to choose the version of the spanning tree to be implemented on the Switch. mstp - Selecting this parameter will set the Multiple Spanning Tree Protocol (MSTP) globally on the Switch. rstp - Selecting this parameter will set the Rapid Spanning Tree Protocol (RSTP) globally on the Switch. stp - Selecting this parameter will set the Spanning Tree Protocol (STP) globally on the Switch. Only Administrator or Operator-level users can issue this command. Example usage: To set the Switch globally for the Multiple Spanning Tree Protocol (MSTP): DES-3800:admin#config stp version mstp Command: config stp version mstp Success. DES-3800:admin# config stp Purpose Syntax Description Parameters Used to setup STP, RSTP and MSTP on the Switch. config stp {maxage | maxhops | hellotime | forwarddelay | txholdcount | fbpdu [enable | disable] | This command is used to setup the Spanning Tree Protocol (STP) for the entire switch. All commands here will be implemented for the STP version that is currently set on the Switch. maxage − This value may be set to ensure that old information does not endlessly circulate through redundant paths in the network, preventing the effective propagation of the new information. Set by the Root Bridge, this value will aid in determining that the Switch has spanning tree configuration values consistent with other devices on the bridged LAN. If the value ages out and a BPDU has still not been received from the Root Bridge, the Switch will start sending its own BPDU to all other switches for permission to become the Root Bridge. If it turns out that your switch has the lowest Bridge Identifier, it will become the Root Bridge. The user may choose a time between 6 and 40 seconds. The default value is 20. maxhops - The number of hops between devices in a spanning tree region before the BPDU (bridge protocol data unit) packet sent by the Switch will be discarded. Each switch on the hop count will reduce the hop count by one until the value reaches zero. The Switch will then discard the BPDU packet and the information held for the port will age out. The user may set a hop count from 1 to 20. The default is 20. hellotime − The user may set the time interval between transmission of configuration messages by the root device in STP, or by 287
