Re: How to overcome port blocking

check the port 2/48 with show port 2/48, is it trunking? Are the native vlan matching?

1. %SPANTREE-2-RX_1QNONTRUNK: Rcved 1Q-BPDU on non-trunk port [dec]/[dec] vlan [dec]

This message indicates that the nontrunking port has received at least one 1Q-tagged spantree BPDU frame on the receiving VLAN. [dec] is the module number, the second [dec] is the port number, and the third [dec] is the VLAN number.

Recommended Action: Either reconfigure the nontrunking port into a 1Q-trunking port, or reconfigure the peer 1Q-trunking port

into a nontrunking port.

2. %SPANTREE-2-RX_1QPVIDERR: Rcved pvid_inc BPDU on 1Q port [dec]/[dec] vlan [dec]

This message indicates that the 1Q-trunking port has received at least one 1Q-tagged spantree BPDU frame with an inconsistent

transmitting VLAN ID to the receiving port VLAN ID. [dec] is the module number, the second [dec] is

the port number, and the third [dec] is the VLAN number.

Recommended Action: Either reconfigure the receiving port VLAN ID to the same VLAN ID of the peer port, or reconfigure the peer port VLAN ID to the same VLAN ID of the receiving port.

3. %SPANTREE-2-RX_BLKPORTPVID: Block [dec]/[dec] on rcving vlan [dec] for inc peer vlan [dec]

This message indicates that the system is blocking the port from receiving traffic on the receiving

VLAN of the BPDU. [dec] is the module number, the second [dec] is the port number, the third [dec] is the receiving VLAN number,and the fourth [dec] is the peer VLAN number.

Recommended Action: Either reconfigure the receiving port VLAN ID to the same VLAN ID of the peer port, or reconfigure the peer port VLAN ID to the same VLAN ID of the receiving port.

Re: How to overcome port blocking

Looks like the port 2/48 should be trunking per mesage still being logged.

1. %SPANTREE-2-RX_1QNONTRUNK: Rcved 1Q-BPDU on non-trunk port [dec]/[dec] vlan [dec]

This message indicates that the nontrunking port has received at least one 1Q-tagged spantree BPDU frame on the receiving VLAN. [dec] is the module number, the second [dec] is the port number, and the third [dec] is the VLAN number.

Recommended Action: Either reconfigure the nontrunking port into a 1Q-trunking port, or reconfigure the peer 1Q-trunking port

into a nontrunking port.
