HPE OfficeConnect 1920 48G Switch - JG927A 48 port 10/100/1000 Mbps + 4 slot SFP.
Tính năng kỹ thuật :
Ports : 48 autosensing 10/100/1000 ports; 4 Gigabit SFP ports.
MIPS @ 650 MHz, 32 MB flash, 128 MB SDRAM; packet buffer size: 1.5 MB
Performance : 100 Mb Latency < 5 µs; 1000 Mb Latency < 5 µs; Throughput up to 77.4 Mpps (64-byte packets); Routing/Switching capacity 104 Gbps; Routing table size 32 entries; MAC address table size 16384
Support : Quality of Service (QoS); Management; Connectivity; Layer 2 switching; Security; Convergence; Resiliency and high availability.
Layer 3 services : Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network; DHCP relay: simplifies management of DHCP addresses in networks with multiple subnets.
Layer 3 routing : NEW Static IPv4/IPv6 routing: provides basic routing (supporting up to 32 static routes and 8 virtual VLAN interfaces); allows manual configuration of routing.
