WebView Switches QoS Tab - Advanced Mode Advanced QoS mode provides rules for specifying flow classification and assigning rule actions that relate to bandwidth management. The rules are based on the Access Control Lists (see Access Control Tab). This feature has been added to version 1.2 of the SRW2024/SRW2016 and version 1.1 of the SRW224G4/SRW248G4. MAC ACLs and IP ACLs can be grouped together in more complex structures, called policies. Policies can be applied to an interface.

The possible field values are: • IP Based ACLs. Matches packets to IP based ACLs first, then matches packets to MAC based ACLs. • MAC Based ACLs. Matches packets to MAC based ACLs first, then matches packets to IP based ACLs. IP ACL. Matches packets to IP based ACLs first, then matches packets to MAC based ACLs. Match.
WebView Switches Spanning Tree Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges. STP also provides one path between end stations on a network, eliminating loops. Loops occur when alternate routes exist between hosts. Loops in an extended network can cause bridges to forward traffic indefinitely, resulting in increased traffic and reducing network efficiency. The device supports the following Spanning Tree versions: • Classic STP.
WebView Switches Root Hello Time (sec). Indicates the device Hello Time. The Hello Time indicates the amount of time in seconds a root bridge waits between configuration messages. The default is 2 seconds. The range is 1 to 10 seconds. Root Forward delay (sec). Indicates the device forward delay time. The Forward Delay Time indicates the amount of time in seconds a bridge remains in a listening and learning state before forwarding packets. The default is 15 seconds. The range is 4 to 30 seconds.
WebView Switches • Long. Specifies 1 through 200,000,000 range for port path costs.The default path costs assigned to an interface varies according to the selected method. Bridge Settings Priority. Specifies the bridge priority value. When switches or bridges are running STP, each is assigned a priority. After exchanging BPDUs, the device with the lowest priority value becomes the Root Bridge. The default value is 32768. The port priority value is provided in increments of 4096.
WebView Switches • Blocking. Indicates that the port is currently blocked and cannot forward traffic or learn MAC addresses. Blocking is displayed when Classic STP is enabled. • Listening. Indicates that the port is in Listening mode. The port cannot forward traffic nor can it learn MAC addresses. • Learning. Indicates that the port is in Learning mode. The port cannot forward traffic, however it can learn new MAC addresses. • Forwarding. Indicates that the port is in Forwarding mode.
WebView Switches Spanning Tree Tab - RSTP Port Settings While the classic spanning tree prevents Layer 2 forwarding loops in a general network topology, convergence can take between 30-60 seconds. This time may delay detecting possible loops, and propagating status topology changes. Rapid Spanning Tree Protocol (RSTP) detects and uses network topologies that allow a faster STP convergence without creating forwarding loops. Interface. Displays the port or LAG on which Rapid STP is enabled. Role.
WebView Switches • Enabled. Enables the device to establish a point-to-point link. To establish communications over a pointto-point link, the originating PPP first sends Link Control Protocol (LCP) packets to configure and test the data link. After a link is established and optional facilities are negotiated as needed by the LCP, the originating PPP sends Network Control Protocols (NCP) packets to select and configure one or more network layer protocols.
WebView Switches Spanning Tree Tab - MSTP Instance Settings MSTP operation maps VLANs into STP instances. Packets assigned to various VLANs are transmitted along different paths within Multiple Spanning Trees Regions (MST Regions). Regions are one or more Multiple Spanning Tree bridges by which frames can be transmitted. In configuring MST, the MST region to which the device belongs is defined. A configuration consists of the name, revision, and region to which the device belongs.
WebView Switches • Boundary Port. Indicates the port is a boundary port. A Boundary port attaches MST bridges to LAN in an outlying region. If the port is a boundary port, it also indicates whether the device on the other side of the link is working in RSTP or STP mode. • Master Port. Indicates the port is a master port. A Master port provides connectivity from a MSTP region to the outlying CIST root. • Internal. Indicates the port is an internal port. Role.
WebView Switches Multicast Tab - IGMP Snooping When IGMP Snooping is enabled globally, all IGMP packets are forwarded to the CPU. The CPU analyzes the incoming packets and determines: • Which ports want to join which Multicast groups? • Which ports have Multicast routers generating IGMP queries? • Which routing protocols are forwarding packets and Multicast traffic? Ports requesting to join a specific Multicast group issue an IGMP report, specifying that Multicast group is accepting members.
WebView Switches Multicast Tab - Bridge Multicast The Bridge Multicast screen displays the ports and LAGs attached to the Multicast service group in the Ports and LAGs tables. The Port and LAG tables also reflect the manner in which the port or LAGs joined the Multicast group. Ports can be added either to existing groups or to new Multicast service groups. The Bridge Multicast screen permits new Multicast service groups to be created.
WebView Switches Multicast Tab - Bridge Multicast Forward All The Bridge Multicast Forward All screen contains fields for attaching ports or LAGs to a device that is attached to a neighboring Multicast router/switch.
