MES53xx, MES33xx, MES23xx Ethernet Switch Series 88
Command creats a specific process and translate the
command interface in its configuration mode.
Commands listed above are applied within the
process:
spanning-tree forward-time seconds;
spanning-tree hello-time seconds ;
spanning-tree max-age seconds ;
spanning-tree priority prior_val
no spanning-tree process id
Delete a specified process.
If you set the STP parameters forward-time, hello-time, max-age, make sure that:
2*(Forward-Delay - 1) >= Max-Age >= 2*(Hello-Time + 1).
Ethernet or port group interface configuration mode commands
Command line prompt in the Ethernet or port group interface configuration mode is as follows:
console(config-if)#
Table 5.72. Ethernet or port group interface configuration mode commands
Disable STP on the interface.
Enable STP on the interface.
cost:
(1..200000000)/seeTable
5.69
Set the cost of a path through this interface.
- cost – path cost.
Set the cost based on the port transfer rate and the method of
determining path cost, see Table 5.65. Ethernet interface and
interface group configuration mode commands
spanning-tree port-priority
priority
Set the interface priority in the STP spanning tree.
Priority value must be divisible by 16.
no spanning-tree
port
spanning-tree portfast
[auto]
Specify the mode in which the port immediately switches to
transmission mode when the link is established, before the
timer expires.
- auto- add 3 second delay before entering the transmission
mode.
no spanning-tree portfast
Enable immediate transition into the transmission mode when
the link is established.
Enable root protection for all STP spanning trees for the
selected port. This protection prohibits the interface to be the
root port of the switch.
no spanning-tree guard
root
spanning-tree bpduguard
{enable | disable}
Enable protection that disables the interface when a BPDU
packet is received.
no spanning-tree
bpduguard
Disable protection that disables the interface when a BPDU
packet is received.
spanning-tree link-type
{point-to-point | shared}
-/'point-to-point' for a
duplex port, 'shared' for a
half-duplex port
Set the RSTP state to 'forwarding' and defines the link type for
a given port:
- point-to-point - point to point;
- shared - shared.
no spanning-tree link-type
spanning-tree bpdu
{filtering | flooding}
Set the BPDU packet processing mode by the interface on
which STP is disabled.
- filtering - BPDU packets are filtered on the interface on
which STP is disabled;
- flooding - untagged BPDU packets are transmitted and
tagged packets are filtered on the interface on which STP is
disabled.
