stp loopback-detection firewall
hello
I need your help for spanning tree.
These are 5130 switches with a firmware: 5130ei-cmw710-boot-r3208p08 where is set the spannin-tree to global and loopback detection on the interfaces
global :
<code>
loopback-detection global enable vlan 1 to 4094
loopback-detection interval-time 5
shutdown-interval 0
#
stp region-configuration
region-name test
revision-level 1
instance 1 vlan 1 to 199
instance 2 vlan 200 to 399
active region-configuration
#
stp instance 0 to 3 priority 8192
stp bpdu-protection
stp global enable
Sur les interfaces:
port link-type hybrid
undo port hybrid vlan 2
port hybrid vlan 3 untagged
port hybrid pvid vlan 3
broadcast-suppression pps 2001
multicast-suppression pps 15001
undo stp enable
sflow flow collector 2
sflow sampling-rate 1025
sflow counter collector 2
sflow counter interval 121
qos trust dscp
poe enable
loopback-detection enable vlan 2 to 4094
loopback-detection action shutdown
</code>
the problem is that when there is a loop on the switch or on a mini switch connect to the switch.
There is a frame that goes back to the firewall for tan on the heart of networks hp5500 there is a parameterized stp:
<code>
stp region-configuration
region-name test
revision-level 2
instance 2 vlan 1 to 199
instance 3 vlan 200 to 399
active region-configuration
#
stp instance 1 priority 0
stp instance 2 priority 0
stp instance 3 priority 0
stp bpdu-protection
stp enable
</code>
and on the interfaces of connections to the firewall there must have been: stp root-protection
On hp5131 on hybrid interfaces there is loopback-detetion control enable.
is that you have an idea to prevent the firewall receiving Tran.?
