Field Description
CIST Bridge
CIST bridge ID, which comprises the device’s priority in the CIST and its
MAC address. For example, in output information
“32768.000f-e200-2200”, the value preceding the period (“.”) is the
device’s priority in the CIST, and the value following the period is the
device’s MAC address.
Bridge Times
Major parameters for the bridge:
z Hello: Hello timer
z MaxAge: Max Age timer
z FWDly: Forward delay timer
z Max Hop: Max hops within the MST region
CIST Root/ERPC
CIST root ID and external path cost (the path cost from the device to the
CIST root)
CIST RegRoot/IRPC
CIST regional root ID and internal path cost (the path cost from the device
to the CIST regional root)
CIST RootPortId
CIST root port ID. “0.0” indicates that the device is the root and there is no
root port.
BPDU-Protection Indicates whether BPDU protection is enabled globally.
Bridge Config-
Digest-Snooping
Indicates whether Digest Snooping is enabled globally on the bridge.
TC or TCN received Number of received TC/TCN packets
Time since last TC Time since the latest topology change
[FORWARDING] The port learns MAC addresses and forwards user traffic
[DISCARDING] The port does not learn MAC addresses or forward user traffic
