Dell Force10 Z9000 FTOS Command Line Reference Guide for the Z9000 System FTOS - Page 991

Multiple Spanning Tree Protocol (MSTP) Multiple spanning tree protocol (MSTP), as implemented by FTOS, conforms to IEEE 802.1s. This command supports the Dell Force10 E-Series, C-Series, S-Series, Z-Series, and S4810 platforms. 30 debug spanning-tree mstp Enable debugging of the multiple spanning tree protocol and view information on the protocol. C-Series, E-Series, S-Series, Z-Series, S4810 Syntax Parameters debug spanning-tree mstp [all | bpdu interface {in | out} | events] all bpdu interface {in | out} (OPTIONAL) Enter the keyword all to debug all spanning tree operations. (OPTIONAL) Enter the keyword bpdu to debug bridge protocol data units (BPDU). (OPTIONAL) Enter the interface keyword along with the type slot/port of the interface you want displayed. Type slot/port options are the following: • For a Fast Ethernet interface, enter the keyword FastEthernet followed by the slot/port information. • For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet followed by the slot/port information. • For a Port Channel interface, enter the keywords portchannel followed by a number. For the C-Series and SSeries, the range is 1 to 128. For the E-Series, the range is 1 to 255 for TeraScale and 1 to 512 for ExaScale. • For a SONET interface, enter the keyword sonet followed by the slot/port information. • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet followed by the slot/port information. • For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE followed by the slot/port information. Optionally, enter an in or out parameter in conjunction with the optional interface: • For Receive, enter the keyword in. 991
