Max Age:
The maximum age of the information transmitted by the Bridge when it is the Root Bridge. Valid values are in the range
6 to 40 seconds, and MaxAge must be <= (FwdDelay-1)*2.
Maximum Hop Count:
This defines the initial value of remaining Hops for MSTI information generated at the boundary of an MSTI region. It
defines how many bridges a root bridge can distribute its BPDU information to. Valid values are in the range 6 to 40
hops.
Transmit Hold Count:
The number of BPDU's a bridge port can send per second. When exceeded, transmission of the next BPDU will be delayed.
Valid values are in the range 1 to 10 BPDU's per second.
Advanced Settings
Edge Port BPDU Filtering:
Control whether a port explicitly configured as Edge will transmit and receive BPDUs.
Edge Port BPDU Guard:
Control whether a port explicitly configured as Edge will disable itself upon reception of a BPDU. The port will enter the
error-disabled state, and will be removed from the active topology.
Port Error Recovery:
Control whether a port in the error-disabled state automatically will be enabled after a certain time. If recovery is not
enabled, ports have to be disabled and re-enabled for normal STP operation. The condition is also cleared by a system
reboot.
Port Error Recovery Timeout:
The time to pass before a port in the error-disabled state can be enabled. Valid values are between 30 and 86400 seconds
(24 hours).

3.4.2 MSTI Mapping
When you implement a Spanning Tree protocol on the switch that the bridge instance the CIST is not available for explicit
mapping, as it will receive the VLANs not explicitly mapped. Due to the reason that you need to set the list of VLANs
mapped to the MSTI. The VLANs must be separated with comma and/or space. A VLAN can only be mapped to one MSTI.
An unused MSTI should just be left empty. (I.e. not having any VLANs mapped to it.)
This section describes how the user can inspect the current STP MSTI bridge instance priority configurations, and possibly
change them as well.
Web Interface
To configure the Spanning Tree MSTI Mapping parameters in the web interface:
1. Click Configuration, Spanning Tree, MSTI Mapping
2. Specify the configuration identification parameters in the field
3. Specify the VLANs Mapped blank field.
4. Click Apply to save the setting
5. If you want to cancel the setting then you need to click the Reset button. It will revert to previously saved values
