NETGEAR 8800 Chassis Switch CLI Manual pvst-plus Specifies the STP encapsulation mode of operation to be PVST+. Default Ports in the default STPD (s0) are dot1d mode. Ports in user-created STPDs are in emistp mode. Usage Guidelines Care must be taken to ensure that ports in overlapping domains do not interfere with the orderly working of each domain's protocol. By default, when the switch boots for the first time, it automatically creates a VLAN named default with a tag value of 1 and STPD s0. The switch associates VLAN default to STPD s0. All ports that belong to this VLAN and STPD are in 802.1d encapsulation mode with autobind enabled. If you disable autobind on the VLAN default, that configuration is saved across a reboot. MSTP STPDs use 802.1D BPDU encapsulation mode by default. To ensure correct operation of your MSTP STPDs, do not configure EMISTP or PVST+ encapsulation mode for MSTP STPDs. Naming Conventions If your STPD has the same name as another component, for example a VLAN, NETGEAR recommends that you specify the identifying keyword as well as the name. If your STPD has a name unique only to that STPD, the keyword stpd is optional. For name creation guidelines and a list of reserved names, see the section "Object Names" in the NETGEAR 8800 User Manual. STP Encapsulation Modes You can specify the following STP encapsulation modes: • dot1d-This mode is reserved for backward compatibility with previous STP versions. BPDUs are sent untagged in 802.1D mode. Because of this, any given physical interface can have only one STPD running in 802.1D mode. This encapsulation mode supports the following STPD modes of operation: 802.1D, 802.1w, and MSTP. • emistp-This mode sends BPDUs with an 802.1Q tag having an STPD ID in the VLAN ID field. This encapsulation mode supports the following STPD modes of operation: 802.1D and 802.1w. • pvst-plus-This mode implements PVST+ in compatibility with third-party switches running this version of STP. The STPDs running in this mode have a one-to-one relationship with VLANs and send and process packets in PVST+ format. Chapter 17. STP Commands | 749

NETGEAR 8800 Chassis Switch CLI Manual

Default

Ports in the default STPD (s0) are

dot1d

mode.

Ports in user-created STPDs are in

emistp

mode.

Usage Guidelines

Care must be taken to ensure that ports in overlapping domains do not interfere with the

orderly working of each domain’s protocol.

By default, when the switch boots for the first time, it automatically creates a VLAN named

default

with a tag value of 1 and STPD

. The switch associates VLAN

default

to STPD

All ports that belong to this VLAN and STPD are in 802.1d encapsulation mode with autobind

enabled. If you disable autobind on the VLAN

default

, that configuration is saved across a

reboot.

MSTP STPDs use 802.1D BPDU encapsulation mode by default. To ensure correct operation

of your MSTP STPDs, do not configure EMISTP or PVST+ encapsulation mode for MSTP

STPDs.

Naming Conventions

If your STPD has the same name as another component, for example a VLAN, NETGEAR

recommends that you specify the identifying keyword as well as the name. If your STPD has

a name unique only to that STPD, the keyword

stpd

is optional. For name creation guidelines

and a list of reserved names, see the section “Object Names” in the

NETGEAR 8800 User

Manual

STP Encapsulation Modes

You can specify the following STP encapsulation modes:

•

dot1d

—This mode is reserved for backward compatibility with previous STP versions.

BPDUs are sent untagged in 802.1D mode. Because of this, any given physical interface

can have only

one

STPD running in 802.1D mode.

This encapsulation mode supports the following STPD modes of operation: 802.1D,

802.1w, and MSTP.

•

emistp

—This mode sends BPDUs with an 802.1Q tag having an STPD ID in the VLAN ID

field.

This encapsulation mode supports the following STPD modes of operation: 802.1D and

802.1w.

•

pvst-plus

—This mode implements PVST+ in compatibility with third-party switches

running this version of STP. The STPDs running in this mode have a one-to-one

relationship with VLANs and send and process packets in PVST+ format.

pvst-plus

Specifies the STP encapsulation mode of operation to be PVST+.
