BPDU that has expired, that MSTI needs to be re-calculated. The max age is meaningless for MSTIs. H3C does not recommend you to set the max age by using this command. Instead, you can use the stp bridge-diameter command to set the network diameter and let MSTP automatically calculates the max age according to the network size.
Page 124: Stp Transmit-Limit
A larger maximum transmission rate value requires more system resources. An appropriate maximum transmission rate setting can limit the speed at which a port sends BPDUs and prevent MSTP from using excessive bandwidth resources during network topology changes. H3C recommends that you use the default value.

After configuring the default VLAN for a trunk port, you must use the port trunk permit vlan command to configure the trunk port to allow packets from the default VLAN to pass through, so that the port can forward packets from the default VLAN. Related commands: port link-type and port trunk permit vlan.
