The switch supports the IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) and IEEE 802.1s Multiple Spanning Tree 
Protocol (MSTP). MSTP allows you to map many VLANs to a small number of spanning tree groups, each with its own 
topology.  
MSTP supports up to 31 Spanning Tree Groups on the switch (STG 32 is reserved for switch management). MRST is 
turned off by default.  
 
NOTE:  When Multiple Spanning Tree is turned on, VLAN 1 is moved from Spanning Tree Group 1 to the 
Common Internal Spanning Tree (CIST). When Multiple Spanning Tree is turned off, VLAN 1 is moved back to 
Spanning Tree Group 1. 
 
The following table describes the Multiple Spanning Tree Configuration Menu options. 
Table 106  Multiple Spanning Tree Configuration Menu options 
Command Description 
cist  Displays the Common Internal Spanning Tree (CIST) Menu. 
name <1-32 characters>  Configures a name for the MSTP region. All devices within a MSTP region must 
have the same region name. 
rev <0-65535>  Configures the revision level for the MSTP region. The revision level is used as a 
numerical identifier for the region. All devices within a MSTP region must have the 
same revision level number. The range is 0-65535. 
maxhop <4-60>  Configures the maximum number of bridge hops a packet may to traverse before 
it is dropped. The range is from 4 to 60 hops. The default is 20. 
mode rstp|mstp  Selects either Rapid Spanning Tree mode (rstp) or Multiple Spanning Tree mode 
(mstp). The default mode is RSTP. 
on  Globally turn RSTP/MSTP ON. 
Note: When RSTP is turned on, the configuration parameters for STP group 1 
apply to RSTP 
off  Globally turn RSTP/MSTP OFF. 
cur  Displays the current RSTP/MSTP configuration.
