D-Link DMS-1250-12 12-Port 2.5G Smart Managed Switch
PRODUCT DESCRIPTION
D-Link DMS-1250-12 12-Port 2.5G Smart Managed Switch (DMS-1250-12) - 5 Years Local Warranty
Multi-Gigabit 2.5G Access with 10G Uplinks
The D-Link DMS-1250-12 is part of D-Link's DMS-1250 series of multi-gigabit smart managed switches. It provides 8 x 2.5G RJ45 ports, 2 x 10GBASE-T RJ45 ports and 2 x 10G SFP+ ports. All 2.5-Gigabit Ethernet ports carry 6 kV surge protection (IEC 61000-4-5).
Performance
D-Link rates the DMS-1250-12 at 120 Gbps switching capacity and 89.29 Mpps maximum forwarding rate, with a 16K-entry MAC address table and jumbo frames up to 12,000 bytes.
L2+ Features and Static Routing
STP/RSTP/MSTP, Ethernet Ring Protection Switching (ERPS), link aggregation, Q-in-Q and Auto Surveillance/Voice VLAN are supported, and static routing (128 IPv4 / 64 IPv6 entries) lets the switch route between VLANs.
Security and Management
ACLs, 802.1X, DHCP server screening, ARP inspection, AAA/RADIUS/TACACS+ and the D-Link Safeguard Engine protect the network. Manage it through the web GUI, full CLI (console port included) and SNMP, or centrally through D-Link Nuclias Connect / the Nuclias Network Controller.

Frequently Asked Questions — D-Link DMS-1250-12
What speeds do the ports support?
The 2.5G RJ45 ports run at 100 Mbps, 1 Gbps or 2.5 Gbps, and the two 10GBASE-T ports at 100 Mbps up to 10 Gbps. The SFP+ ports take 10G SFP+ modules or DAC cables.
Does it route between VLANs?
Yes, with static routing: up to 128 IPv4 and 64 IPv6 static routes. Dynamic routing protocols are not listed in D-Link's datasheet.
Can DMS-1250 switches be stacked?
Physical stacking is not listed in D-Link's datasheet. For central management use Nuclias Connect or the Nuclias Network Controller.
Why are the weight and power figures not listed?
D-Link's datasheet and product page publish different figures for this model, so we have left them out. Ask us and we will confirm before you plan rack space and power.
What warranty do I get?
5 years local warranty in Singapore, supplied by SourceIT with a GST invoice.
