Page 186: Power Over Ethernet Configuration
ONFIGURING THE WITCH Power Over Ethernet Configuration This switch can provide DC power to a wide range of connected devices, eliminating the need for an additional power source and cutting down on the amount of cables attached to each device. Once configured to supply power, an automatic detection process is initialized by the switch that is authenticated by a PoE signature from the connected device.
Page 187: Switch Power Status
OWER THERNET ONFIGURATION Switch Power Status Displays the current status of power parameters for the switch. Command Attributes • Maximum Available Power – The current configured power budget for the switch. (Default 375 watts) • System Operation Status – The current operating PoE power status for the switch.
Page 188: Setting A Switch Power Budget
ONFIGURING THE WITCH Setting a Switch Power Budget A maximum PoE power budget for the switch (power available to all switch ports) can be defined so that power can be centrally managed, preventing overload conditions at the power source. If the power demand from devices connected to the switch exceeds the power budget setting, the switch uses port power priority settings to limit the supplied power.

Page 196: Spanning Tree Algorithm Configuration
ONFIGURING THE WITCH Spanning Tree Algorithm Configuration The Spanning Tree Algorithm (STA) can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the switch to interact with other bridging devices (that is, an STA-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link...
Page 197: Displaying Global Settings
PANNING LGORITHM ONFIGURATION RSTP is designed as a general replacement for the slower, legacy STP. RSTP achieves must faster reconfiguration (i.e., around one tenth of the time required by STP) by reducing the number of state changes before active ports start learning, predefining an alternate route that can be used when a node or port fails, and retaining the forwarding database for ports insensitive to changes in the tree structure when reconfiguration occurs.
Page 198 ONFIGURING THE WITCH • Designated Root – The priority and MAC address of the device in the Spanning Tree that this switch has accepted as the root device. - Root Port – The number of the port on this switch that is closest to the root.
Page 199 PANNING LGORITHM ONFIGURATION • Root Forward Delay – The maximum time (in seconds) this device will wait before changing states (i.e., discarding to learning to forwarding). This delay is required because every device must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that would make it return to a discarding state;...

Page 202 ONFIGURING THE WITCH • Priority – Bridge priority is used in selecting the root device, root port, and designated port. The device with the highest priority becomes the STA root device. However, if all devices have the same priority, the device with the lowest MAC address will then become the root device.
Page 203 PANNING LGORITHM ONFIGURATION Configuration Settings for RSTP The following attributes apply to both STP and RSTP • Path Cost Method – The path cost is used to determine the best path between devices. The path cost method is used to determine the range of values that can be assigned to each interface.

Page 208: Configuring Interface Settings
ONFIGURING THE WITCH Configuring Interface Settings You can configure RSTP attributes for specific interfaces, including port priority, path cost, link type, and edge port. You may use a different priority or path cost for ports of the same media type to indicate the preferred path, link type to indicate a point-to-point connection or shared-media connection, and edge port to indicate if the attached device can support fast forwarding.
Page 209 PANNING LGORITHM ONFIGURATION • Path Cost – This parameter is used by the STP to determine the best path between devices. Therefore, lower values should be assigned to ports attached to faster media, and higher values assigned to ports with slower media.
Page 210 ONFIGURING THE WITCH • Migration – If at any time the switch detects STP BPDUs, including Configuration or Topology Change Notification BPDUs, it will automatically set the selected interface to forced STP-compatible mode. However, you can also use the Protocol Migration button to manually re-check the appropriate BPDU format (RSTP or STP-compatible) to send on the selected interfaces.
Page 211: Vlan Configuration
VLAN C ONFIGURATION VLAN Configuration IEEE 802.1Q VLANs In large networks, routers are used to isolate broadcast traffic for each subnet into separate domains. This switch provides a similar service at Layer 2 by using VLANs to organize any group of network nodes into separate broadcast domains.
Page 212: Assigning Ports To Vlans
ONFIGURING THE WITCH Assigning Ports to VLANs Before enabling VLANs for the switch, you must first assign each port to the VLAN group(s) in which it will participate. By default all ports are assigned to VLAN 1 as untagged ports. Add a port as a tagged port if you want it to carry traffic for one or more VLANs, and any intermediate network devices or the host at the other end of the connection supports VLANs.
Page 213 VLAN C ONFIGURATION Port Overlapping – Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as file servers or printers. Note that if you implement VLANs which do not overlap, but still need to communicate, you can connect them by enabled routing on this switch.
Page 214 ONFIGURING THE WITCH To implement GVRP in a network, first add the host devices to the required VLANs (using the operating system or other application software), so that these VLANs can be propagated onto the network. For both the edge switches attached directly to these hosts, and core switches in the network, enable GVRP on the links between these devices.
Page 215: Enabling Or Disabling Gvrp (Global Setting)
VLAN C ONFIGURATION Ports can be assigned to multiple tagged or untagged VLANs. Each port on the switch is therefore capable of passing tagged or untagged frames. When forwarding a frame from this switch along a path that contains any VLAN-aware devices, the switch should include VLAN tags.

Page 384: Access Control List Commands
OMMAND NTERFACE Access Control List Commands Access Control Lists (ACL) provide packet filtering for IP frames (based on address, protocol, Layer 4 protocol port number or TCP control code) or any frames (based on MAC address or Ethernet type). To filter packets, first create an access list, add the required rules, specify a mask to modify the precedence in which the rules are checked, and then bind the list to a specific port.
Page 385 CCESS ONTROL OMMANDS • This switch supports ACLs for both ingress and egress filtering. However, you can only bind one IP ACL and one MAC ACL to any port for ingress filtering, and one IP ACL and one MAC ACL to any port for egress filtering.
Page 386 OMMAND NTERFACE The order in which active ACLs are checked is as follows: 1. User-defined rules in the Egress MAC ACL for egress ports. 2. User-defined rules in the Egress IP ACL for egress ports. 3. User-defined rules in the Ingress MAC ACL for ingress ports. 4.

Page 474: Spanning-Tree Mode
OMMAND NTERFACE Command Usage The Spanning Tree Algorithm (STA) can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the switch to interact with other bridging devices (that is, an STA-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.
Page 475: Spanning-Tree Forward-Time
PANNING OMMANDS Command Usage • Spanning Tree Protocol Uses RSTP for the internal state machine, but sends only 802.1D BPDUs. • Rapid Spanning Tree Protocol RSTP supports connections to either STP or RSTP nodes by monitoring the incoming protocol messages and dynamically adjusting the type of protocol messages the RSTP node transmits, as described below: - STP Mode –...

Page 486: Spanning-Tree Protocol-Migration
OMMAND NTERFACE • When automatic detection is selected, the switch derives the link type from the duplex mode. A full-duplex interface is considered a point-to-point link, while a half-duplex interface is assumed to be on a shared link. • RSTP only works on point-to-point links between two bridges. If you designate a port as a shared link, RSTP is forbidden.
Page 487: Show Spanning-Tree
PANNING OMMANDS Command Usage If at any time the switch detects STP BPDUs, including Configuration or Topology Change Notification BPDUs, it will automatically set the selected interface to forced STP-compatible mode. However, you can also use the spanning-tree protocol-migration command at any time to manually re-check the appropriate BPDU format to send on the selected interfaces (i.e., RSTP or STP-compatible).

LOSSARY Access Control List (ACL) ACLs can limit network traffic and restrict access to certain users or devices by checking each packet for certain IP or MAC (i.e., Layer 2) information. Address Resolution Protocol (ARP) ARP converts between IP addresses and MAC (i.e., hardware) addresses. ARP is used to locate the MAC address corresponding to a given IP address.
Page 558 LOSSARY Dynamic Host Control Protocol (DHCP) Provides a framework for passing configuration information to hosts on a TCP/IP network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability of automatic allocation of reusable network addresses and additional configuration options. Extensible Authentication Protocol over LAN (EAPOL) EAPOL is a client authentication protocol used by this switch to verify the network access rights for any device that is plugged into the switch.
Page 559: Igmp Snooping
LOSSARY IEEE 802.1Q VLAN Tagging—Defines Ethernet frame tags which carry VLAN information. It allows switches to assign endstations to different virtual LANs, and defines a standard way for VLANs to communicate across switched networks. IEEE 802.1p An IEEE standard for providing quality of service (QoS) in Ethernet networks. The standard uses packet tags that define up to eight traffic classes and allows switches to transmit packets based on the tagged priority value.
Page 560: Igmp Query
LOSSARY IGMP Query On each subnetwork, one IGMP-capable device will act as the querier — that is, the device that asks all hosts to report on the IP multicast groups they wish to join or to which they already belong. The elected querier will be the device with the lowest IP address in the subnetwork.
Page 561: Port Mirroring
LOSSARY Link Aggregation See Port Trunk. Link Aggregation Control Protocol (LACP) Allows ports to automatically negotiate a trunked link with LACP-configured ports on another device. Management Information Base (MIB) An acronym for Management Information Base. It is a set of database objects that contains information about a specific device.
Page 562 LOSSARY Port Trunk Defines a network link aggregation and trunking method which specifies how to create a single high-speed logical link that combines several lower-speed physical links. Remote Authentication Dial-in User Service (RADIUS) RADIUS is a logon authentication protocol that uses software running on a central server to control access to RADIUS-compliant devices on the network.
Page 563 LOSSARY Spanning Tree Protocol (STP) A technology that checks your network for any loops. A loop can often occur in complicated or backup linked network systems. Spanning Tree detects and directs data along the shortest available path, maximizing the performance and efficiency of the network.
