configuration file, ports are numbered in the order in which the
device add
commands are given,
starting from 1. If no arguments are given, the current settings for each port are displayed.
Example 1:
DSL bridge>
portfilter 2 3 4 5
DSL bridge>
portfilter 3 1
Example 2:
DSL bridge>
portfilter 2 all
DSL bridge>
portfilter 3 all
8. status
Syntax:
Status
Description:
This command shows the status of the bridge and its ports. The status information for a port
includes the SNMP type information about time exceeded packets, packets discarded, etc. It
also includes the broadcast history of the port over the last five seconds and the high water
mark of packets queued on the bridge for this device.
Example:
DSL bridge>
status
9. spanning disable | enable
Syntax:
spanning disable
spanning enable
Description:
When spanning tree operation is disabled, the bridge operates in transparent mode and all bridge
ports are set to the forwarding state.
When spanning tree operation is enabled, the state of the bridge’s ports is controlled by the
spanning tree process.
The
status
command reports the state of the spanning tree process.
Configuration saving saves this information. By default, spanning tree operation is enabled.
Example:
DSL bridge>
spanning disable
DSL bridge>
spanning enable
10. spanning forwarddelay
Syntax:
spanning forwarddelay [<time>]
Description:
Reads or sets the time in seconds, in which the bridge remains in the listening or learning states,
and is used when the bridge is or is attempting to become the root bridge. The forward delay time
may be any value between 4 and 30 but it is also constrained by the maximum age and hello times.
The forward delay time may also by changed by SNMP command. The
maxage
,
hellotime
and
forwarddelay
times are constrained as follows:
2
×
(forwarddelay - 1)
≥
maxage
maxage
≥
2
×
(hel 1)
Configuration saving saves this information. By default the forward delay time is set to 15
seconds.
Example:
DSL bridge>
spanning forwarddelay 10
;
Sets the forwarding
delay to 10 seconds.
