Use undo stp transmit-limit to restore the default. Syntax stp transmit-limit limit undo stp transmit-limit Default The BPDU transmission rate of each port is 10. Views Ethernet interface view, aggregate interface view Predefined user roles network-admin Parameters limit: Sets the BPDU transmission rate in the range of 1 to 255. Usage guidelines The maximum number of BPDUs that a port can send within each hello time equals the BPDU transmission rate plus the hello timer value. A larger BPDU transmission rate value requires more system resources. An appropriate BPDU transmission rate setting can prevent spanning tree protocols from using excessive bandwidth resources during network topology changes. HP recommends that you use the default value. When the setting is configured in Ethernet interface view, it takes effect on only that interface. When the setting is configured in aggregate interface view, it takes effect on only the aggregate interface. When the setting is configured on a member port in an aggregation group, it takes effect only after the port leaves the aggregation group. Examples # Set the BPDU transmission rate of port FortyGigE 1/1/1 to 5. system-view [Sysname] interface fortygige 1/1/1 [Sysname-FortyGigE1/1/1] stp transmit-limit 5 vlan-mapping modulo Use vlan-mapping modulo to map VLANs in the MST region to MSTIs according to the specified modulo value and quickly create a VLAN-to-instance mapping table. Syntax vlan-mapping modulo modulo Default All VLANs are mapped to the CIST (MSTI 0). Views MST region view 137
