STG configuration fields  

The following table describes the STG Configuration fields.


Field Description
Id
The ID number for the STG.
Note: The STG ID and TaggedBpduVlanId must be unique in the STG table. If you change the STG ID without updating TaggedBpduVlanId, the insertion may fail because of a duplicate TaggedBpduVlanId.
Type
Specifies the type of STG.
  • normal = normal STG
  • svlan = stacked VLAN STG
Priority
Sets the STP bridge priority, in decimal. The range is 0 (highest priority) to 65535 (lowest priority). The default is 32768.
BridgeMaxAge
The value in hundredths of a second that all bridges use for MaxAge when this bridge is acting as the root.
Note: The 802.1D-1990 standard specifies that the BridgeMaxAge range is related to the value of dot1dStpBridgeHelloTime. The default is 2000 (20 seconds).
BridgeHelloTime
The value in hundredths of a second that all bridges use for HelloTime when this bridge is acting as the root. The granularity of this timer is specified by the IEEE 802.1D-1990 standard to be in increments of 1/100 of a second. The default is 200 (2 seconds).
BridgeForwardDelay
The value in hundredths of a second that all bridges use for Forward Delay when this bridge is acting as the root. The default is 1500 (15 seconds).
EnableSTP
Enables or disables the spanning tree algorithm for the STG.
StpTrapEnable
Enables SNMP traps to be sent to trace receiver every time an STP topology occurs.
TaggedBpduAddress
Represents a MAC address; specifically for tagged BPDUs.
TaggedBpduVlanId
Represents the VLAN tag associated with the STG. This ID is used to tag BPDUs through a non-IEEE tagging bridge to another 8000 Series switch.
Note: By default, the TaggedBpduVlanId is an address calculated based on the STG ID by Device Manager. Accepting the default value calculated by Device Manager makes it much simpler to coordinate STGs across multiple switches. If you enter a custom value for this field, you must manually coordinate it across all switches.
Note: The STG ID and TaggedBpduVlanId must be unique in the STG table. If you change the STG ID without updating TaggedBpduVlanId, the insertion may fail because of a duplicate TaggedBpduVlanId.
Port Members
The ports you want to become members of the new STG.
Ports are not selectable if:
  • configured as single port SMLT, MLT-base SMLT, or IST
  • configured as members of any other STG
