Table 24 Common Internal Spanning Tree parameter descriptions Parameter MaxAge FwdDel Hops Priority (port) Cost State Role Designated Bridge Designated Port Hello Type Description The maximum age parameter specifies, in seconds, the maximum time the bridge waits without receiving a configuration bridge protocol data unit before it reconfigures the STP network. The forward delay parameter specifies, in seconds, the amount of time that a bridge port has to wait before it changes from learning state to forwarding state. Shows the maximum number of bridge hops allowed before a packet is dropped. 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. 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 zero (0) indicates that the cost will be set to the appropriate default after the link speed has been auto-negotiated. Shows the current state of the port. The state field can be one of the following: Discarding (DISC), Learning (LRN), Forwarding (FWD), or Disabled (DSB). 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), Master (MAST), or Unknown (UNK). Shows information about the bridge connected to each port, if applicable. Information includes the priority (hex) and MAC address of the Designated Bridge. The port ID of the port on the Designated Bridge to which this port is connected. Information includes the port priority (hex) and the port number (hex). The hello time parameter specifies, in seconds, how often the root bridge transmits a configuration bridge protocol data unit (BPDU). Any bridge that is not the root bridge uses the root bridge hello value. Type of link connected to the port, and whether the port is an edge port. Link type values are AUTO, P2P, or SHARED. Trunk group information Command: /info/l2/trunk Trunk group 1, Enabled port state: 17: STG 1 forwarding 18: STG 1 forwarding When trunk groups are configured, you can view the state of each port in the various trunk groups. NOTE: If Spanning Tree Protocol on any port in the trunk group is set to forwarding, the remaining ports in the trunk group will also be set to forwarding. Information Menu 42

Common Internal Spanning Tree parameter descriptions

Parameter

Description

MaxAge

The maximum age parameter specifies, in seconds, the maximum time the bridge

waits without receiving a configuration bridge protocol data unit before it

reconfigures the STP network.

FwdDel

The forward delay parameter specifies, in seconds, the amount of time that a bridge

port has to wait before it changes from learning state to forwarding state.

Hops

Shows the maximum number of bridge hops allowed before a packet is dropped.

Priority (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

zero (0) indicates that the cost will be set to the appropriate default after the link

speed has been auto-negotiated.

State

Shows the current state of the port. The state field can be one of the following:

Discarding

(

DISC

Learning

(

LRN

)

Forwarding

(

FWD

), or

Disabled

(

DSB

)

Role

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),

Master (MAST), or Unknown (UNK).

Designated Bridge

Shows information about the bridge connected to each port, if applicable.

Information includes the priority (hex) 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.

Information includes the port priority (hex) and the port number (hex).

Hello

The hello time parameter specifies, in seconds, how often the root bridge transmits a

configuration bridge protocol data unit (BPDU). Any bridge that is not the root bridge

uses the root bridge hello value.

Type

Type of link connected to the port, and whether the port is an edge port. Link type

values are AUTO, P2P, or SHARED.

Trunk group information

Command:

/info/l2/trunk

Trunk group 1, Enabled

port state:

17: STG

1 forwarding

18: STG

1 forwarding

When trunk groups are configured, you can view the state of each port in the various trunk groups.

NOTE:

If Spanning Tree Protocol on any port in the trunk group is set to forwarding, the remaining ports in the

trunk group will also be set to forwarding.
