The following port ‐ specific CIST information is also displayed:
FwdDel The forward delay parameter specifies, in seconds, the
amount of time that a bridge port has to wait before it
changes from discarding state to learning state and from
learning state to forwarding state.
Hops The maximum number of bridge hops a packet can traverse
before it is dropped. The default value is
20
.

CIST Parameter Descriptions
Parameter Description
Prio (port) The port priority parameter helps determine which bridge
port becomes the designated port. In a network topology that
has multiple bridge ports connected to a single segment, the
port with the lowest port priority becomes the designated
port for the segment.
Cost The port path cost parameter is used to help determine the
designated port for a segment. Generally speaking, the faster
the port, the lower the path cost. A setting of 0 indicates that
the cost will be set to the appropriate default after the link
speed has been auto negotiated.
State The state field shows the current state of the port. The state
field can be either Discarding (
DISC
), Learning (
LRN
) or
Forwarding (
FWD
).
Role The Role field shows the current role of this port in the
Spanning Tree. The port role can be one of the following:
Designated (
DESG
), Root (
ROOT
), Alternate (
ALTN
), Backup
(
BKUP
), Disabled (
DSB
) or Master (
MAST
).
Designated
Bridge
The Designated Bridge shows information about the bridge
connected to each port, if applicable. Information includes
the priority (in hexadecimal notation) and MAC address of
the Designated Bridge.
Designated Port The port ID of the port on the Designated Bridge to which
this port is connected.
Type Type of link connected to the port, and whether the port is an
edge port. Link type values are
AUTO
,
P2P
or
SHARED
.
