Parameters detail — Displays detailed information.
Output Show Service-ID STP Output — The following table describes show service-id STP output
fields:
Label Description
RSTP Admin State
Indicates the administrative state of the Rapid Spanning Tree
Protocol instance associated with this service.
Core Connectivity
Indicates the connectivity status to the core.
RSTP Oper State
Indicates the operational state of the Rapid Spanning Tree Protocol
instance associated with this service. This field is applicable only
when STP is enabled on the router.
Bridge-id
Specifies the MAC address used to identify this bridge in the
network.
Hold Time
Specifies the interval length during which no more than two
Configuration BPDUs shall be transmitted by this bridge.
