BPDU Protection - 5130 EI Switches

[Ed Nicoll]

Can someone help me with the config for edged port BPDU protection on the 5130? We have configured our edge ports using the following commands but when you do a DISPLAY STP BRIEF it tells me that the protection is NONE. 

stp edged-port

and in the main config we have used the following commands:

stp global enable

stp bpdu-protection

This config works ok on 5500 EI switches but must be different on Comware 7. Any help would be much appreciated. Thank you.

Hi,

I think the output of that command is a bit strange. The guide says that the "Protection" column should be BPDU, if you have bpdu guard on. How ever i can reproduce your result. I run  Release 3113P05.

STP conf:

 stp mode pvst
 stp bpdu-protection
 stp pathcost-standard dot1t
 stp global enable

Test interface:

interface GigabitEthernet1/0/2
 port access vlan 599
 stp edged-port
 poe enable

If I run : display stp brief, i get the same output, protection NONE. Even though the port is stp edged-port.

doing a : display stp - you can see that BPDU is configured for the port (if the link is up).

-------[VLAN 599 Global Info]-------
 Protocol status     : Enabled

----[Port2(GigabitEthernet1/0/2)][FORWARDING]----

 Port times          : Hello 2s MaxAge 20s FwdDelay 15s MsgAge 1s

And it works - if i connect a link that transmits BPDU's. It shuts.

%Oct 14 14:37:27:648 2016 HP-5130-24G IFNET/3/PHY_UPDOWN: GigabitEthernet1/0/2 link status is up.
%Oct 14 14:37:27:670 2016 HP-5130-24G IFNET/5/LINK_UPDOWN: Line protocol on the interface GigabitEthernet1/0/2 is up.
%Oct 14 14:37:30:449 2016 HP-5130-24G STP/4/STP_BPDU_PROTECTION: BPDU-Protection port GigabitEthernet1/0/2 received BPDUs.
%Oct 14 14:37:30:490 2016 HP-5130-24G IFNET/3/PHY_UPDOWN: GigabitEthernet1/0/2 link status is down.
%Oct 14 14:37:30:492 2016 HP-5130-24G IFNET/5/LINK_UPDOWN: Line protocol on the interface GigabitEthernet1/0/2 is down.

So it works, but the output of display stp brief is strange I think.

Regards.

Probably, config=xxxxx shows configured value , whereas active=xxxxxx shows current status

Point-to-point is configured as auto, and somehow ended up in enabled state.
