Spaning Tree Edge Ports

Hi All

 

I haVe a network with STP problems in a Procurve system, with about 60 switches. 

.- Structure

   1. One core switch, with a only one fiber link to others racks

   2. In each rack, the fiber link to one switch, and this switch in cascade with other one or two switches

   3. The last switch in the rack for voice and wifi services

   4. MSTP config:

          - spanning-tree config-name "HVELA"
          - spanning-tree config-revision 1
          - spanning-tree instance 1 vlan 100-102 105
          - spanning-tree instance 2 vlan 103 104

   5. Voice VLAN 2xx, where xx is different in each rack

   6. Voice controller is in 101 VLAN

 

I have some voice ports in the next state:

show log -r

I 05/25/17 15:05:36 ports: port 39 is now off-line
I 05/25/17 15:05:33 ports: port 37 is now on-line
I 05/25/17 15:05:33 ports: port 37 is Blocked by STP
I 05/25/17 15:05:31 ports: port 37 is now off-line
I 05/25/17 15:03:04 ports: port 20 is now on-line
I 05/25/17 15:03:04 ports: port 20 is Blocked by STP
I 05/25/17 15:03:02 ports: port 20 is now off-line
I 05/25/17 15:02:58 ports: port 20 is now on-line
I 05/25/17 15:02:58 ports: port 20 is Blocked by STP
I 05/25/17 15:02:56 ports: port 20 is now off-line

 

I have configured all ports 1-48 with :

- bpdu-filter bpdu-protection

- admin-edge-port

- loop-protect

- bpdu-filter

And globally:

- loop-protect trap loop-detected

- loop-protect disable-timer 60

- spanning-tree trap errant-bpdu

 

This problem is in all voice swtiches. 

 

Thank you all

Re: Spaning Tree Edge Ports

When you say you have configured this stuff on all ports 1-48, if any of those ports are not Access ports, but provide uplinks to other switches, you shopuld remove that config from them.
