Layer 2 functions
• Prevents packet loss with back pressure (half duplex) and IEEE 802.3x pause frame flow control (full duplex)
• High performance of Store-and-Forward architecture and runt / CRC filtering eliminates erroneous packets to optimize the network bandwidth
• Support storm control hotel - Broadcast / Multicast / unicast / Unknown unicast • Supports VLAN hotel - IEEE 802.1Q tagged VLAN Up to 255 VLAN groups out of 4095 VLAN ID Provider Bridging (VLAN Q-in-Q) support (IEEE 802.1ad) - Private VLAN Edge (PVE) - Protocol based VLAN MAC-based VLAN IP Subnetbaseret VLAN Voice VLAN Management VLAN • supports Spanning Tree Protocol hotel - STP, IEEE 802.1D Spanning Tree Protocol - RSTP, IEEE 802.1w Rapid Spanning Tree Protocol - MSTP, IEEE 802.1s Multiple Spanning Tree Protocol (city VLAN) - TP BPDU Guard and BPDU filtering • supports linkaggregering hotel - IEEE 802.3ad Link Aggregation Control Protocol (LACP) - Cisco ether-channel (Static trunk) - Maximum 12 trunkg syrups, up to 8 ports per. Trunkgruppe - Up to 16 Gbps bandwidth (full duplex mode) • Provides Port Mirror (many-to-1)
• Port Mirroring to monitor the incoming or outgoing traffic on a particular port
• Loop Protection to prevent broadcast loops
Layer 3 IP routing functions • Support for a maximum of 32 static routes and route software summing
the quality of service • Reduction of the input forms and output speed per. Port bandwidth control
• 8 priority queues on all switch ports
• Traffic Classification hotel - IEEE 802.1p CoS - TOS / DSCP / IP priority of IPv4 / IPv6 packets - IP TCP / UDP port number - Typical network application - Strict priority and WRR) CoS policies - Traffic Political policy switchport- DSCP remark
Multicast • Supports IGMP snooping v1, v2 and v3 for IPv4 multicasting network

• MVR (Multicast VLAN registration)
Security
Approval - IEEE 802.1x port-based / MAC-based network access authentication - Built-in RADIUS client to cooperate with RADIUS servers - TACACS + login users access authentication - RADIUS / TACACS + users can access authentication • access Control List
- IPv4 / IPv6 IP-based ACL MAC-based ACLs • MAC / IP adresseindbinding
• Por tsikkerhed to the source MAC address filtering
• DHCP snooping to filter mistillidige DHCP messages
• Dynamic ARP inspection discards ARP packets with invalid MAC address to IP address binding
• IP source guard prevents IP spoofing attacks
• Auto DoS rule to defend DoS attacks
• Manage IP address access to prevent unauthorized intruder
Management
IPv4 and IPv6 dual stack management
