| Performance Features |
| Port Auto-sensing |
Auto-sensing of port speed and auto-negotiation of duplex on all switch ports for optimizing bandwidth |
| Auto MDI/MDIX |
Medium-dependent interface crossover ( Auto-MDIX ) capability on 10/100 and 10/100/1000 mbps interfaces that enables the interface to automatically detect the required cable type ( straight thru or crossover ) and to configure the connection appropriately |
| 802.3x flow control |
IEEE 802.3x flow control on all ports. ( The switch does not initiate pause frames ) |
| Storm Control |
Storm control prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unicast storm on one of the physical interfaces. A LAN storm occurs when packets flood the LAN, creating excessive traffic and degrading network performance. Storm Control enables limits to be placed on broadcast, multicast and unicast traffic |
| Static MAC Addressing |
This feature enables the manual configuration of the MAC addresses on a per port basis. Flooding is prevented by retaining MAC entries across a reboot of the switch. |
| Port Blocking |
Port Blocking provides the ability to block the flooding of unknown layer 2 unicast and multicast traffic on an Interface |
| IPV4 IGMP Snooping |
Internet Group Management Protocol ( IGMP ) constrains the flooding of multicast traffic by dynamically configuring Layer 2 interfaces so that multicast traffic is forwarded to only those interfaces associated with IP multicast devices.
IGMPv1, v2, v3, IGMP snooping querier mode, IGMP report suppression, topology change notification and robustness variable features are supported
|
| Port Quick Disconnect |
In some network environments, it is desirable to move an Ethernet from one switch port to another and have the device come on-line quickly. The Port Quick Disconnect feature if enabled, provides an immediate age-out of the MAC addresses learned on the port when the port status changes from a link-up to a link-down state |
| Manageability Features |
| Web Device Manager |
The Perle Web Device Manager is an embedded Web based application that provides an easy to use browser interface for managing the switch. Unlike competitive products, Java applet technology is not required or used |
| Command Line Interface ( CLI ) |
A familiar text-based Command Line Interface that is based on accepted industry standard syntax and structure. Ideal for CCNA and CCNP trained engineers, this interface is available via in-band Telnet or the out-band serial console port |
| SNMP |
Manage the switch with an snmp compatible management station that is running platforms such as HP Openview or Perle’s PerleVIEW NMS. SNMP V1 and V2C |
| PerleVIEW |
PerleVIEW is Perle’s SNMP-based network management system that provides a view of the network with a large scale of Perle networking devices. |
| IPv6 |
Manage with an IPv4 or IPV6 address |
| DHCP Client Auto-Configuration |
Automates configuration of switch information such as IP address, default gateway, hostname and Domain Name System ( DNS ) as well as TFTP server names. Firmware and configuration file locations are provided through options 54, 66, 67, 125 and 150 |
| DHCP Relay |
DHCP Relay is used for forwarding requests from DHCP clients when they are not on the same physical subnet. As a DHCP relay agent the switch operates as a Layer 3 device that forwards DHCP packets between clients and servers. |
| DHCP Option 82 Insertion |
Normally used in metro or large enterprise deployments DHCP Option 82 insertion is used to provide additional information on “physical attachment” of the client. As per RFC 3046, option 82 enables additional pre-defined information to be inserted into the DHCP request packet ( for DHCP Servers that support this option ) |
| LLDP |
LLDP-Link Layer Discovery Protocol as per IEEE 802.1AB is a neighbor discovery protocol that is used for network devices to advertise information about themselves to other devices on the network. This protocol runs over the data-link layer, which allows two systems running different network layer protocols to learn about each other ( via TLVs – Type-Length-Value ) |
| File Download |
Firmware can be transferred via TFTP or HTTP. Text-based files that can be created or edited by common text editors. |
| Availability and Redundancy Features |
| Spanning Tree Protocol ( STP ) |
IEEE 802.1D now incorporated in IEEE 802.1Q-2014, STP prevents bridge loops and the broadcast radiation that results from them. |
| Rapid Spanning Tree Protocol ( RSTP ) |
Interoperable with STP, RSTP ( IEEE 802.1w ) takes advantage of point-to-point wiring and provides rapid convergence of the spanning tree. Reconfiguration of the spanning tree can occur in less than 1 second |
| P-Ring |
P-Ring provides an easy to use method for configuring a ring network using standard spanning tree protocols.
Prevents a switch loop scenario in a ring topology.
|
| Link Standby |
A link recovery feature using a primary and backup link. Provides a simple alternative to spanning tree protocols for link redundancy |
| VLAN Features |
| VLAN Range |
Up to 256 VLANS across a VLAN ID range of 1 to 4000 |
| VLAN Interfaces |
Perle switches provide the ability to configure management VLAN interfaces. This enables network administrators to access the switch’s management interface from separate VLAN networks |
| Monitoring Features |
| Port Mirroring |
N:1 Port Mirroring is a method of monitoring network traffic. With port mirroring enabled, the switch sends a copy of one or more ports to a predefined destination port. Selection of Transmit, Receive frames or both can be made |
| RMON |
RMON statistics provided for statistics, history, alarms and events for network monitoring and traffic analysis |
| Syslog |
Facility for logging systems messages to an external SYSLOG server |
| Alert Log |
Facility for logging systems messages locally |
| Traceroute |
Layer 2 traceroute to identify the path that a frame takes from source to destination |
| Virtual cable test |
A test that enables the detection of potential copper cabling issues such as pair polarity pair swaps and excessive pair skew as well as any opens, shorts or any impedance mismatch. Will report the distance in the cable to the open or short. |
| Power Supply Monitoring |
Provides the status of power supplies of the switch |
| Alarm Processing |
The switch can monitor global switch conditions as well as individual ports. These alarms can be configured to send messages to ;
- an internal log file
- external Syslog server
- SNMP trap server
- An external alarm device such as a bell, light or other signaling device via the switch’s built-in dry contact alarm relay
Global Status Monitoring Alarms
Port Status Monitoring Alarms
- Link Fault Alarm ( IE loss of signal )
- Port not forwarding alarm
- Port not operating alarm ( failure upon start up tests )
- FCS Bit error rate alarm
