EX4550(virtual-chassis): interfaces blocked by stp

‎10-11-2016 09:41 PM

Hi everyone,

 

Yesterday, EX4550 switch(virtual chassis  12.3R9-S1 ), A fortress machine access to the interface ge-0/0/10, the adapter can not learn MAC, ge-0/0/16 replacement, the same can not learn MAC. Again to ge-1/0/16, normal learning. One server has two NICs connected to x-0/0/8 and xe-1/0/8. Xe-0/0/8 to xe-0/0/21, and found that xe-0/0/21 can not learn MAC.

 

so, ge-0/0/10, ge-0/0/16, ge-1/0/17  is down, However, the interface display is blocked by STP.

 How to eliminate the Blocked interface? The switch is configured with point-to-point RSTP for all interfaces. Why does the interface Down also show that STP Blocked?

Is there anyone who has ever seen the situation? thank you very much

Hi, 

 

Can you run below commands to see for any reason why port was STP blocked:

show interfaces x/x/x | match bpdu
show spanning-tree bridge show spanning-tree interface show spanning-tree interface x/x/x detail

For servers, you could configure the ports as stp edge.

 

Cheers,

Ashvin

Hi,

 

"show interfaces xe-0/0/21 | match "bpdu" , display:" bpdu: none ", 

"show spanning-tree interface", And did not find the interface was blocked
