Hello,

We are having some issues with one of our uplinks between cities, it
seems that they are cutting STP packets. I would like to know if there
is similar command to that from cisco:

Edge#sh spanning-tree vlan 101 detail

VLAN0101 is executing the rstp compatible Spanning Tree protocol
Bridge Identifier has priority 4096, address 000b.4515.3065
Configured hello time 2, max age 20, forward delay 15, tranmsit
hold-count 6
We are the root of the spanning tree
Topology change flag not set, detected flag not set
Number of topology changes 1 last change occurred 01:38:56 ago
from GigabitEthernet2/16
Times: hold 1, topology change 35, notification 2
hello 2, max age 20, forward delay 15
Timers: hello 0, topology change 0, notification 0, aging 300

Port 144 (GigabitEthernet2/16) of VLAN0101 is designated forwarding
Port path cost 4, Port priority 128, Port Identifier 128.144.
Designated root has priority 4096, address 000b.4515.3065
Designated bridge has priority 4096, address 000b.4515.3065
Designated port id is 128.144, designated path cost 0
Timers: message age 0, forward delay 0, hold 0
Number of transitions to forwarding state: 1
Link type is point-to-point by default
Loop guard is enabled by default on the port
BPDU: sent 2919, received 0

Where I can find the last line "BPDU: sent 2919, received 0"?

Thanks!

You can use the following commands:

show log counters STP.OutBPDU occurred

show log counters STP.InBPDU occurred

"clear counter" will reset these values as well.

X480-24x.38 # show log counters STP.OutBPDU occurred
Component SubComponent Condition Severity Occurred I
Ntfd
----------- ------------ ----------------------- ------------- -------- -
----
STP OutBPDU Dump Debug-Data 1 N
0
STP OutBPDU Trace Debug-Verbose 2 N
0

This will give you a hint if the STP BPDU's are sent/received.
If you want you can then decide to add these to your log filter to display
these packets/events in greater detail to your log/syslog.

Thanks! That works :). Is it possible to see it per interface or do I
need to enable verbose logging?
