Ports & interfaces
Installed SFP modules quantity An SFP ("small form-factor pluggable transceiver") is a transmitter/receiver which interfaces a network device motherboard (e.g. in a switch, router) to a fibre optic or copper network cable. The "SFP ports quantity" is the number of ports for SFP connections in a device.	20
Installed SFP+ modules quantity An SFP ("small form-factor pluggable transceiver") is a transmitter/receiver which interfaces a network device motherboard (e.g. in a switch, router) to a fibre optic or copper network cable. The enhanced small form-factor pluggable (SFP+) is an enhanced version of the SFP that supports data rates up to 10 Gbit/s. The "SFP+ ports quantity" is the number of ports for SFP+ connections in a device.	4
Combo SFP ports quantity	4
Console port	RJ-45/Mini-USB
USB 2.0 ports quantity Number of USB 2.0 ports (connecting interfaces) in the device. USB 2.0 was released in April 2000 (now called "Hi-Speed"), adding higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), USB 2.0 ports are usually black.	1

Network

10G support The product can use Oracle 10G, which is a database management system introduced in 2003.
Copper ethernet cabling technology	10BASE-T,100BASE-TX,1000BASE-T
Port mirroring
Full duplex A full-duplex system allows communication in both directions, and unlike half-duplex, allows this to happen simultaneously.
Routing entries	16000
Flow control support
Link aggregation
Broadcast storm control
Spanning tree protocol
VLAN support A Virtual Local Area Network (VLAN) consists of a group of computers and switches that can be physically distributed over different networks and buildings, but form one LAN on a logical level.
Virtual LAN features	Stacked VLAN,Private VLAN,Tagged VLAN,Port-based VLAN
Number of VLANs	4094

Data transmission
Switching capacity The data transfer capacity of the switch per second.	128 Gbit/s
Throughput	95.24 Mpps
MAC address table The MAC address is the 'Media Access Control Address'. It is a unique address given to a network interface controller (NIC) in a device. A MAC address table shows the addresses in a table format.	68000 entries
Number of queues	8
Number of IP interfaces	256
Jumbo frames support
Jumbo frames	12000
Packet buffer memory	4 MB

Security
DHCP features	DHCP server,DHCP client
Access Control List (ACL)
IGMP snooping
Security algorithms Security algorithms are used to provide authentication, cipher key generation, integrity and radio link privacy to users on mobile networks. The security algorithms supported are the ones that can be used with this product.	802.1x RADIUS,SSH,SSH-2,SSL/TLS
MAC address filtering Security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists.
SSH/SSL support
Loop protection
BPDU filtering/protection
Authentication	Guest VLAN,Port-based authentication

Multicast features
Multicast support

Protocols
Management protocols	SNMP, NTPv3/v4, Telnet
Supported network protocols Network protocols tested as compatible with this product e.g. FTP,HTML, POP.	IPv4/v6
