D-Link DES-1210-52/ME - Config Stp Ports

DES-1210-52/ME L2 Metro Ethernet Switch CLI Reference Guide
154
the STP version that is currently set on the Switch.
Parameters
maxage <value 6-40> − This value may be set to ensure that old
information does not endlessly circulate through redundant paths in
the network, preventing the effective propagation of the new
information. Set by the Root Bridge, this value aids in determining
that the Switch has spanning tree configuration values consistent
with other devices on the bridged LAN. If the value ages out and a
BPDU has still not been received from the Root Bridge, the Switch
starts sending its own BPDU to all other switches for permission to
become the Root Bridge. If your switch has the lowest priority, it
becomes the Root Bridge. The user may choose a time between 6
and 40 seconds. The default value is 20.
hellotime <value 1-10> − The user may set the time interval between
transmission of configuration messages by the root device in STP,
or by the designated router, thus stating that the Switch is still
functioning. The value may be between 1 and 10 seconds. The
default value is 2 seconds.
forwarddelay <value 4-30> − The amount of time (in seconds) that
the root device will wait before changing from Blocking to Listening ,
and from Listening to Learning states. The value may be between 4
and 30 seconds. The default is 15 seconds.
txholdcount <value 1-10> − The maximum number of BDPU Hello
packets transmitted per interval. Default value = 3.
Restrictions
Only administrator-level users can issue this command.
Example usage:
To configure STP with maxage 18 and hellotime 2:
DES-1210-52/ME:5# config stp hellotime 2 forwarddelay 4 maxage 6
txholdcount 2
Command: config stp hellotime 2 forwarddelay 4 maxage 6 txholdcount 2
Success.
DES-1210-52/ME:5#
config stp ports
Purpose
To setup STP on the port level.
Syntax
config stp ports <portlist> {externalcost [auto | <value 1-
200000000>] | edge [auto | true | false] | hellotime <value 1-2> |
p2p [true | false | auto ] | state [enable | disable] | fbpdu [enable
| disable] | migrate [yes | no] | priority <value 0-240> |
restricted_role [true | false] | restricted_tcn [true | false] }
Description
The config stp ports command configures STP for a group of ports.
Parameters
<portlist> – A port or range of ports to be configured. The port list is
specified by listing switch number and the beginning port number on
that switch, separated by a colon. Then the highest port number of
the range is specified. The beginning and end of the port list range
are separated by a dash.
externalCost − Defines a metric that indicates the relative cost of
forwarding packets to the specified port list. Port cost can be set
automatically or as a metric value. The default value is auto.
