Hello,
I am little bit confused between the theory and the output results.
As per my knowledge, PVST+ is the extension of 802.1d(STP) and
Rapid-PVST+ is RSTP(802.1w).
Then Alternate port role belongs to Rapid-PVST+ not PVST+, But in the
output of PVST+, It shows "ALTR BLK". It should be in the blocking
state.
and same output shows in the Rapid-PVST+ "Altr BLK".
Whereas debug results are fine:
Debug PVST+
"blocking" 01:09:27: STP: VLAN0017 Fa0/24 -> blocking
Debug Rapid-PVST+
01:08:51: RSTP(17): updt roles, received superior bpdu on Fa0/24
01:08:51: RSTP(17): Fa0/24 is now alternate
PVST+ = blocking
Rapid-PVST+ = alternate
Is there any 'show' command where I can see the accurate result.
One more thing to ask that How much time PVST+ will take to come in
the Forwarding state from the Blocking state.( in default settings)
