    BPS 2000 with software version 1.2 or across a Pure BPS 2000 Stack with software version 1.2. If you are working with more than 64 VLANs in a Pure BPS 2000 Stack and you change to a Hybrid Stack, you lose all VLANs. However, if you have up to 64 VLANs in the Pure BPS 2000 Stack and you change to a Hybrid Stack, you will retain all the VLANs.

  • Page 49: Multiple Spanning Tree Protocol Groups

    Starting with software version 1.2, the BPS 2000 supports multiple spanning tree groups (STGs). The BPS 2000 supports a maximum of 8 STGs, either all in one standalone switch or across a stack consisting of only BPS 2000 switches (Pure BPS 2000 Stack mode).
  • Page 50 256 VLANs. With a maximum of 8 STGs, on average, each STG will have 32 VLANs. In the default configuration of the BPS 2000, a single STG with the ID of 1 includes all ports on the switch. It is called the default STG. Although ports can be added to or deleted from the default STG, the default STG (STG1) itself cannot be deleted from the system.

  • Page 51: Stg Configuration Guidelines

    STG. • When a tagged port belongs to more than one STG, the egress BPDUs are tagged to distinguish the BPDUs of one STG from those of another STG. Using the Business Policy Switch 2000 Version 1.2...
  • Page 52 Because some STP-compliant devices do not support tagging, you can configure whether to send tagged or untagged BPDUs, even from tagged ports, with the BPS 2000 with software version 1.2. The VLAN ID for the tagged BPDUs will be 4000+STG ID.

  • Page 53: Spanning Tree Fast Learning

    Spanning Tree Fast Learning is an enhanced port mode supported by the BPS 2000. If you enable Spanning Tree Fast Learning on a port with no other bridges, the port is brought up more quickly following the switch initialization or a spanning tree change.

  • Page 64 The default setting for AutoPVID is Off; you must enable this feature. • Protocol-based VLANs A protocol-based VLAN is a VLAN in which you assign your switch ports as members of a broadcast domain, based on the protocol information within the packet. Protocol-based VLANs can localize broadcast traffic and assure that only the protocol-based VLAN ports are flooded with the specified protocol type packets.

    Independent VLAN Learning (IVL) mode—Each VLAN uses a unique forwarding database. The IVL mode is only an option when using the Business Policy Switch 2000; you must use the SVL mode when operating a hybrid stack. Business Policy Switches support up to 64 VLANs (port-, protocol-, or MAC SA-based), including VLAN #1 which is always port-based.

  • Page 66: Security

    If you are working with more than 64 VLANs in a Pure BPS 2000 Stack and you change to a Hybrid Stack, you lose all VLANs. However, if you have up to 64 VLANs in the Pure BPS 2000 Stack and you change to a Hybrid Stack, you will retain all the VLANs.

    Ports BPS 2000 ports are classified into three categories: trusted, untrusted, and unrestricted ports. These three categories are also referred to as interface classes.

    IEEE 802.1p Drop precedence The Business Policy Switch does not trust the DSCP of IP traffic received from an untrusted port, but it does trust the DSCP of IP traffic received from a trusted port. Filters installed on trusted ports cannot change the DSCP of the IP packets received on these ports.
