Description of Software Features
– 39 –
◆ Rapid Spanning Tree Protocol (RSTP, IEEE 802.1w) – This protocol reduces the
convergence time for network topology changes to about 3 to 5 seconds,
compared to 30 seconds or more for the older IEEE 802.1D STP standard. It is
intended as a complete replacement for STP, but can still interoperate with
switches running the older standard by automatically reconfiguring ports to
STP-compliant mode if they detect STP protocol messages from attached
devices.
◆ Multiple Spanning Tree Protocol (MSTP, IEEE 802.1s) – This protocol is a direct
extension of RSTP. It can provide an independent spanning tree for different
VLANs. It simplifies network management, provides for even faster
convergence than RSTP by limiting the size of each region, and prevents VLAN
members from being segmented from the rest of the group (as sometimes
occurs with IEEE 802.1D STP).
Virtual LANs The switch supports up to 4094 VLANs. A Virtual LAN is a collection of network
nodes that share the same collision domain regardless of their physical location or
connection point in the network. The switch supports tagged VLANs based on the
IEEE 802.1Q standard. Members of VLAN groups can be dynamically learned via
GVRP, or ports can be manually assigned to a specific set of VLANs. This allows the
switch to restrict traffic to the VLAN groups to which a user has been assigned. By
segmenting your network into VLANs, you can:
◆ Eliminate broadcast storms which severely degrade performance in a flat
network.
◆ Simplify network management for node changes/moves by remotely
configuring VLAN membership for any port, rather than having to manually
change the network connection.
◆ Provide data security by restricting all traffic to the originating VLAN, except
where a connection is explicitly defined via the switch's routing service.
◆ Use protocol VLANs to restrict traffic to specified interfaces based on protocol
type.
IEEE 802.1Q Tunneling
(QinQ)
This feature is designed for service providers carrying traffic for multiple customers
across their networks. QinQ tunneling is used to maintain customer-specific VLAN
and Layer 2 protocol configurations even when different customers use the same
internal VLAN IDs. This is accomplished by inserting Service Provider VLAN
(SPVLAN) tags into the customer’s frames when they enter the service provider’s
network, and then stripping the tags when the frames leave the network.
Traffic Prioritization This switch prioritizes each packet based on the required level of service, using
eight priority queues with strict priority, Weighted Round Robin (WRR) scheduling,
or a combination of strict and weighted queuing. It uses IEEE 802.1p and 802.1Q
tags to prioritize incoming traffic based on input from the end-station application.
