Version 9.10(0.0) 9.8(2.0) 9.8(1.0) 9.8(0.0P5) 9.8(0.0P2) 9.7(0.0) 9.2(1.0) 9.0.2.0 8.3.19.0 8.3.11.1 8.3.7.0 8.2.1.0 Description Introduced on the S3148. Introduced on the S3100 series. Introduced on the Z9100-ON. Introduced on the S4048-ON. Introduced on the S3048-ON. Introduced on the S6000-ON. Introduced on the Z9500. Introduced on the S6000. Introduced on the S4820T. Introduced on the Z9000. Introduced on the S4810. Introduced. Usage Information Some non-Dell Networking systems which have hybrid ports participating in PVST+ transmit two kinds of BPDUs: an 802.1D BPDU and an untagged PVST+ BPDU. Dell Networking systems do not expect PVST+ BPDU on an untagged port. If this happens, Dell Networking OS places the port in the Error-Disable state. This behavior might result in the network not converging. To prevent Dell Networking OS from executing this action, use the no spanning-tree pvst err-disable command cause invalid-pvst-bpdu.
