If power is dropped to some low-priority ports and later the power demands on the switch fall back within its budget, the dropped power is automatically restored. Switch Power Status Displays the Power over Ethernet parameters for the switch.
Page 184: Setting A Switch Power Budget
Configuring the Switch 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.

Configuring the Switch • If a device is connected to a critical or high-priority port and causes the switch to exceed its budget, port power is turned on, but the switch drops power to one or more lower-priority ports. Note: Power is dropped from low-priority ports in sequence starting from port number 1.
Page 187: Address Table Settings
Address Table Settings Address Table Settings Switches store the addresses for all known devices. This information is used to pass traffic directly between the inbound and outbound ports. All the addresses learned by monitoring traffic are stored in the dynamic address table. You can also manually configure static addresses that are bound to a specific port.

Page 190: Spanning Tree Algorithm Configuration
Configuring the Switch 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 goes down.
Page 191 Spanning Tree Algorithm Configuration MSTP – MSTP When using STP or RSTP, it may be difficult to maintain a stable path between all VLAN members. Frequent changes in the tree structure can easily isolate some of the group members. MSTP (which is based on RSTP for fast convergence) is designed to support independent spanning trees based on VLAN groups.
Page 192: Displaying Global Settings For Sta
Configuring the Switch Once you specify the VLANs to include in a Multiple Spanning Tree Instance (MSTI), the protocol will automatically build an MSTI tree to maintain connectivity among each of the VLANs. MSTP maintains contact with the global network because each instance is treated as an RSTP node in the Common Spanning Tree (CST).
Page 193 Spanning Tree Algorithm Configuration These additional parameters are only displayed for the CLI: • Spanning tree mode – Specifies the type of spanning tree used on this switch: - STP: Spanning Tree Protocol (IEEE 802.1D) - RSTP: Rapid Spanning Tree (IEEE 802.1w) - MSTP: Multiple Spanning Tree (IEEE 802.1s) •...

Spanning Tree Algorithm Configuration Configuring Global Settings for STA Global settings apply to the entire switch. Command Usage • Spanning Tree Protocol Uses RSTP for the internal state machine, but sends only 802.1D BPDUs. This creates one spanning tree instance for the entire network. If multiple VLANs are implemented on a network, the path between specific VLAN members may be inadvertently disabled to prevent network loops, thus isolating group members.
Page 196 Configuring the Switch • 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.

Layer 2 Flow for Packets Coming into a Tunnel Access Port A QinQ tunnel port may receive either tagged or untagged packets. No matter how many tags the incoming packet has, it is treated as tagged packet.
Page 228 Configuring the Switch Layer 2 Flow for Packets Coming into a Tunnel Uplink Port An uplink port receives one of the following packets: • Untagged • One tag (CVLAN or SPVLAN) • Double tag (CVLAN + SPVLAN) The ingress process does source and destination lookups. If both lookups are successful, the ingress process writes the packet to memory.
Page 229: Enabling Qinq Tunneling On The Switch
VLAN Configuration • Static trunk port groups are compatible with QinQ tunnel ports as long as the QinQ configuration is consistent within a trunk port group. • The native VLAN (VLAN 1) is not normally added to transmitted frames.

Page 262: Displaying Interfaces Attached To A Multicast Router
Configuring the Switch Displaying Interfaces Attached to a Multicast Router Multicast routers that are attached to ports on the switch use information obtained from IGMP, along with a multicast routing protocol such as DVMRP or PIM, to support IP multicasting across the Internet. These routers may be dynamically discovered by the switch or statically assigned to an interface on the switch.
Page 263: Specifying Static Interfaces For A Multicast Router
Multicast Filtering Specifying Static Interfaces for a Multicast Router Depending on your network connections, IGMP snooping may not always be able to locate the IGMP querier. Therefore, if the IGMP querier is a known multicast router/ switch connected over the network to an interface (port or trunk) on your switch, you can manually configure the interface (and a specified VLAN) to join all the current multicast groups supported by the attached router.

Page 271: Multicast Vlan Registration
Multicast Filtering Multicast VLAN Registration Multicast VLAN Registration (MVR) is a protocol that controls access to a single network-wide VLAN most commonly used for transmitting multicast traffic (such as television channels or video-on-demand) across a service provider’s network. Any multicast traffic entering an MVR VLAN is sent to all attached subscribers. This protocol can significantly reduce to processing overhead required to dynamically monitor and establish the distribution tree for a normal multicast VLAN.
Page 272: Configuring Global Mvr Settings
Configuring the Switch Configuring Global MVR Settings The global settings for Multicast VLAN Registration (MVR) include enabling or disabling MVR for the switch, selecting the VLAN that will serve as the sole channel for common multicast streams supported by the service provider, and assigning the multicast group address for each of these services to the MVR VLAN.

Page 411: General Security Measures
General Security Measures General Security Measures This switch supports many methods of segregating traffic for clients attached to each of the data ports, and for ensuring that only authorized clients gain access to the network. Private VLANs and port-based authentication using IEEE 802.1X are commonly used for these purposes.
Page 412: Port Security Commands
Command Line Interface Port Security Commands These commands can be used to enable port security on a port. When using port security, the switch stops learning new MAC addresses on the specified port when it has reached a configured maximum number. Only incoming traffic with source addresses already stored in the dynamic or static address table for this port will be authorized to access the network.
Page 413 General Security Measures Command Usage • If you enable port security, the switch stops learning new MAC addresses on the specified port when it has reached a configured maximum number. Only incoming traffic with source addresses already stored in the dynamic or static address table will be accepted.
Page 414: Network Access (Mac Address Authentication)
Command Line Interface Network Access (MAC Address Authentication) Network Access authentication controls access to the network by authenticating the MAC address of each host that attempts to connect to a switch port. Traffic received from a specific MAC address is forwarded by the switch only if the source MAC address is successfully authenticated by a central RADIUS server.
Page 415: Network-Access Mode
General Security Measures Command Usage The maximum number of MAC addresses per port is 2048, and the maximum number of secure MAC addresses supported for the switch system is 1024. When the limit is reached, all new MAC addresses are treated as authentication failures.

Page 517: Configuring Ieee 802.1Q Tunneling
VLAN Commands Configuring IEEE 802.1Q Tunneling IEEE 802.1Q tunneling (QinQ tunneling) uses a single Service Provider VLAN (SPVLAN) for customers who have multiple VLANs. Customer VLAN IDs are preserved and traffic from different customers is segregated within the service provider’s network even when they use the same customer-specific VLAN IDs. QinQ tunneling expands VLAN space by using a VLAN-in-VLAN hierarchy, preserving the customer’s original tagged packets, and adding SPVLAN tags to each frame (also called double tagging).

Page 572: Multicast Vlan Registration Commands
Command Line Interface Multicast VLAN Registration Commands This section describes commands used to configure Multicast VLAN Registration (MVR). A single network-wide VLAN can be used to transmit multicast traffic (such as television channels) across a service provider’s network. Any multicast traffic entering an MVR VLAN is sent to all subscribers.
Page 573 Multicast Filtering Commands Command Mode Global Configuration Command Usage • Use the mvr group command to statically configure all multicast group addresses that will join the MVR VLAN. Any multicast data associated an MVR group is sent from all source ports, and to all receiver ports that have registered to receive data from that multicast group.
Page 574: Mvr (Interface Configuration)
Command Line Interface mvr (Interface Configuration) This command configures an interface as an MVR receiver or source port using the type keyword, enables immediate leave capability using the immediate keyword, or configures an interface as a static member of the MVR VLAN using the group keyword.
Page 575: Show Mvr
Multicast Filtering Commands • Immediate leave applies only to receiver ports. When enabled, the receiver port is immediately removed from the multicast group identified in the leave message. When immediate leave is disabled, the switch follows the standard rules by sending a group-specific query to the receiver port and waiting for a response to determine if there are any remaining subscribers for that multicast group before removing the port from the group list.

Glossary 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. Boot Protocol (BOOTP) used to provide bootup information for network devices, including IP BOOTP is address information, the address of the TFTP server that contains the devices system files, and the name of the boot file.
Page 598 Glossary DHCP Snooping A technique used to enhance network security by snooping on DHCP server messages to track the physical location of hosts, ensure that hosts only use the IP addresses assigned to them, and ensure that only authorized DHCP servers are accessible.
Page 599 Glossary 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. IEEE 802.1s An IEEE standard for the Multiple Spanning Tree Protocol (MSTP) which provides independent spanning trees for VLAN groups.
Page 600 Glossary IP Multicast Filtering A process whereby this switch can pass multicast traffic along to participating hosts. IP Precedence The Type of Service (ToS) octet in the IPv4 header includes three precedence bits defining eight different priority levels ranging from highest priority for network control packets to lowest priority for routine traffic.
Page 601 Glossary Multiple Spanning Tree Protocol (MSTP) MSTP 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.
Page 602 Glossary Remote Monitoring (RMON) RMON provides comprehensive network monitoring capabilities.
