5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide
334
External Port Path Cost
Cost across boundary region to reach to the root bridge of the CIST.
Designated Root
Identifier of the designated root within the CST.
Root Path Cost
Root path cost to reach the LAN.
Designated Bridge
The bridge containing the designated port.
Designated Port Identifier
Port offering lowest cost to LAN on the Designated Bridge.
Topology Change
Acknowledgement
If a topology change is in progress, this represents the value of
flag in
next Configuration Bridge Protocol Data Unit (BPDU) transmission.
Hello Time
The designated hello time.
Edge Port
The value identifying an edge port.
Edge Port Status
Derived value of the edge port status. True if an edge port, false
otherwise.
Point To Point MAC Status
Derived value indentifying a point to point link.
CST Regional Root
The regional root identifier in use for this port.
CST Internal Root Path
Cost
Internal root path cost to the LAN by the designated external port.
Loop Inconsistent State
The current loop state. While loop guard is enabled, the port fails to
receive BPDUs. Loop inconsistent state maintains the port in a blocking
state until a subsequent BPDU is received.
Transitions Into Loop
Inconsistent State
The number of times transitioned into a loop inconsistent state.
Transitions Out of Loop
Inconsistent State
The number of times this interface has transitioned out of loop
inconsistent state.
5-243 show spanning-tree mst port summary
Display the settings of one or all ports within the multiple spanning tree instance. The parameter
mstid
displays the particular MST instance. The parameter
{slot/port | lag lag-id | all}
indicates the switch port,
LAG, or all ports.
A 0 (defined as the default CIST ID) value for
mstid
, the status summary is displayed for one or all ports.
show spanning-tree mst port summary mstid {slot/port | active | lag lag-id | all)
Parameters
mstid
Enter a multiple spanning tree instance identifier.
slot/port
Enter an interface in slot/port format.
active
Enter active to select all active interfaces.
lag lag-id
Enter into interface lag mode.
all
Enter all for all interfaces.
