Description
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).
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).
Enables (check box is selected) or disables (check box is cleared) the
spanning tree algorithm for the STG.
Enables SNMP traps to be sent to the trace receiver each time an
STP topology occurs (check box is selected).
Represents a MAC address. This address is used specifically for
tagged BPDUs. This field is assigned by the system.
Represents the VLAN tag associated with the STG. This ID is used to
tag BPDUs through a non-IEEE tagging bridge to another Ethernet
Routing Switch 8000 Series.
By default, the TaggedBpduVlanId is an address calculated by Device
Manager based on the STG ID. 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.
The STG ID and TaggedBpduVlanId must be unique in the STG table.
If you change the STG ID without updating TaggedBpduVlanId, the
insertion can fail because of a duplicate TaggedBpduVlanId.
The ports you want to become members of the new STG.
Ports are not selectable if configured as members of any other STG.
