Getting Switch Analytics

From the Switches page, you can click Details on the web interface to display detailed information about a switch.

Summary

PoE reset from the Switch Panel : User can mouse-over to the PoE port of the switch port panel and power-cycle the port, so the device attached to the port will be rebooted

Total PoE Usage: This bar graph displays the consumed, remaining, and total wattage utilized by Power over Ethernet.

Total PoE Utilization by Port: Displays the current PoE utilization by each port, in watts.

System Setting

The System Settings section allows you to configure all primary networking options for your switch.

Spanning Tree Protocol

A Spanning Tree Protocol is a Layer 2 protocol that prevents loops in a network with redundant paths created by multiple switches. We recommend using this feature if your environment incorporates multiple switches.

Procedure

  1. Enable the STP option

  2. Select a Protocol

  3. Select a Bridge Priority value

  4. Click Apply

LLDP

The Link Layer Discovery Protocol (LLDP) is a Layer 2, vendor-neutral protocol that allows network devices to advertise capabilities, identity, and other information. This data can potentially be queried by SNMP.

Procedure

  1. Enable the LLDP option

  2. Click Apply

Voice VLAN

The Voice VLAN feature configures switches to automatically allow and prioritize voice traffic over a designated VLAN. This keeps voice traffic separate and prioritized over other traffic types.

Mode: Allows you to define the Voice VLAN mode.

  • Auto: Automatically advertises the Voice VLAN to connected devices via the LLDP-MED protocol.

  • OUIs: Determines whether a received packet is a voice packet by checking its source MAC address.

Switch Voice VLAN: Allows you to choose what VLAN is used for Voice VLAN. You can setup VLANs in Port Settings.

QoS Priority: Lets you to define whether the switch will use the Quality of Service CoS value of the incoming packet, or tag the packet with a CoS value between 1-7.

OUIs: VoIP traffic has a pre-configured Organizationally Unique Identifier (OUI) prefix in the source MAC address. You can manually add a specific manufacturer's MAC address and description to the OUI table. All traffic received on the Voice VLAN ports from the specific IP phone with a listed OUI is forwarded on the voice VLAN.

QoS

Quality of service (QoS) allows operators to prioritize application traffic to ensure that latency-affected data, such as VoIP and video conferencing, is uninterrupted during periods of network congestion. Switches implement this by reading tagged packets and prioritizing them accordingly. Packets are classified using Class of Service (CoS) on the data link layer, and Differentiated Services Code Points (DSCP) on the network layer, mapped to a queue, then sent out accordingly as per QoS.

Trust Mode: Allows you to define whether the switch will use CoS, DSCP, or both trust modes for QoS.

Scheduling Method: Allows you to define what method the switch will use when assessing transmitting incoming packets in queues. Strict priority always prioritizes queues with a higher priority, while Weighted Round Robin (WRR) weights each queue by priority, then applies a round-robin policy when choosing packets for transmission.

Queue Mapping: Tagged packets are sent to queues defined in this setting. For each CoS or DSCP value, you can choose the queue to which tagged packets are mapped.

IGMP

IGMP Snooping is used for controlling multicast traffic. It listens to IGMP messages being processed by the switch and prevents these messages from being sent to hosts not part of the respective multicast.

Version: The available IGMP Snooping versions are v2 and v3. You can select either/or in the Version dropdown.

VLANS: You can enable IGMP Snooping for any VLAN by selecting the corresponding checkbox next to the VLAN ID.

Jumbo Frame

Ethernet has used the 1500 byte frame size since its inception. Jumbo frames are network layer PDUs that have a size much larger than the typical 1500 byte Ethernet Maximum Transmission Unit (MTU) size. Jumbo frames extend Ethernet to 9000 bytes, making them large enough to carry an 8 KB application datagram plus packet header overhead. If you intend to leave the local area network at high speeds, the dynamics of TCP will require you to use large frame sizes.

The switch supports a jumbo frame size of up to 9216 bytes. Jumbo frames need to be configured to work on the ingress and egress port of each device along the end-to-end transmission path. Furthermore, all devices in the network must also be consistent on the maximum jumbo frame size, so it is important to do a thorough investigation of all your devices in the communication paths to validate their settings.

Jumbo Frame : Enter the size of a jumbo frame. The range is from 1522 to 9216 bytes.

Port Settings

Selecting one or more ports and clicking Configure will display the following settings:

Link: Allows you to enable or disable the connection for this port.

Label: Allows you to add a descriptor for this port.

Speed/Duplex: Allows you to define the following speed/duplex communication settings for this port:

  • Auto: Speed/Duplex will auto-negotiate based on the connected node.

  • 1Gbps / Full Duplex

  • 100 Mbps / Full Duplex

  • 100 Mbps / Half Duplex

  • 10 Mbps / Full Duplex

  • 10 Mbps / Half Duplex

Power over Ethernet (PoE): Allows you to power a connected device through an Ethernet cable using your switch.

VLANs: Allows you to group devices to create a partitioned network on the same LAN.

Isolation: Allows you to configure a port to transmit traffic only to its connected node.

Rate Limit: Allows you to limit the amount of incoming and outgoing traffic in Mbps.

Flow Control: Enabling this will have the switch regulate traffic during times of congestion.

QoS: If QoS is enabled in Switch Settings, you can configure additional settings per port.

  • CoS Value: All incoming packets that lack a CoS value will use the one set in this dropdown.

  • Trust CoS: If checked, the switch will queue packets tagged with CoS into their designated queues. If unchecked, all packets will leave the same queue.

Realtime Meters

System Metrics is primarily for viewing real time statistics . By default there are two types of data:

  • CPU

  • Memory

Capturing data over a period of time allows you to see trends useful for determining the overall performance of your switch.

Override System setting on the Switch Network-wide setting

System setting is followed by Switch setting from the Configure > Switch settings as default settings. If you want individual AP System settings to be different from the Switch Network- wide setting , you can click below part in the screen to override the setting .
