MES3000 Ethernet switch series 95
no spanning-tree max-age
Restore the default value.
spanning-tree priority priority
priority:
(0..61440)/32768
Set the priority of the STP spanning tree.
Priority value must be divisible by 4096.
no spanning-tree priority
Restore the default value.
spanning-tree pathcost
method {long | short}
-/short
Set the method for defining the path value.
- long—value in the range 1..200000000
- short—value in the range 1..65535.
no spanning-tree pathcost
method
Restore the default value.
spanning-tree restrictedtcn
-/disabled
Forbid reception of BPDU with TCN flag.
no spanning-tree
restrictedtcn
Allow reception of BPDU with TCN flag.
spanning-tree bpdu {filtering |
flooding | bridging}
-/flooding
Define BPDU packet processing mode by the interface with
disabled STP.
- filtering—packets are filtered for the interface with STP disabled
- flooding—untagged BDPU packets are transmitted for the
interface with STP disabled, tagged packets are filtered
- bridging – BPDU packets are transmitted through the interface
with disabled STP
no spanning-tree bpdu
Restore the default value.
spanning-tree process id
id: (1..31)/0
The command creates the separate process and transfers the
command interface to the configuration mode.
no spanning-tree process id
Remove the selected process.
When setting forward-time, hello-time, max-age STP parameters, you should take into
account the following inequation:
2*(Forward-Delay - 1) >= Max-Age >= 2*(Hello-Time + 1).
Ethernet interface configuration mode commands, port group interface
Command line request in Ethernet interface, port group interface configuration mode appears as
follows:
console(config-if)#
Table 5.86 —Ethernet interface configuration mode commands, port group
Command
Value/Default value
Action
spanning-tree disable
-/enabled
Disable STP operation for the configured interface.
no spanning-tree disable
Enable STP operation for the configured interface.
spanning-tree cost cost
cost: (1..200000000)/
see Table 5.87
Set path value via the following interface.
no spanning-tree cost
Set the value based on the port transfer rate and the method of
route value definition, table 5.87.
spanning-tree port-priority
priority
priority: (0..240)/128
Set the interface priority in the STP spanning tree.
Priority value must be divisible by 16.
no spanning-tree port-priority
Restore the default value.
spanning-tree portfast [auto]
-
Enable mode, where port immediately switches to transmission
mode when the link is established without waiting for the timer
expiration.
- auto—add 3 second delay before entering the transmission
mode.
no spanning-tree portfast
Disable momentary transition into transmission mode when the
link is established.
spanning-tree guard root
-/protection disabled
Enable root protection for all spanning trees for the selected port.
Such protection denies the interface to be the root port of the
switch.
no spanning-tree guard root
Restore the default value.
spanning-tree bpduguard
-/protection disabled
Enable protection that disables the interface when BPDU packet is
received.
no spanning-tree bpduguard
Disable protection that disables the interface when BPDU packet is
