Cisco-SG550X-24-K9-EU Switch Specifications
| Model | Cisco-SG550X-24-K9-EU |
| Performance | |
| Capacity in Millions of Packets per Second (mpps) (64-byte packets) | 63.09 |
| Switching Capacity (Gbps) | 84.8 |
| Layer 2 Switching | |
| Spanning Tree Protocol | Standard 802.1d spanning tree support |
| Port grouping/link aggregation | Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)
● Up to 8 groups ● Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation |
| VLAN translation | Support for VLAN One-to-One Mapping. In VLAN One-to-One Mapping, on an edge interface C-VLANs are mapped to S-VLANs and the original C-VLAN tags are replaced by the specified S-VLAN |
| Q-in-Q | VLANs transparently cross a service provider network while isolating traffic among customers |
| GVRP/GARP | Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain |
| HOL blocking | Head-Of-Line (HOL) blocking |
| Layer 3 | |
| Wirespeed IPv6 static routing | Up to 1,792 routes and up to 256 IPv6 interfaces |
| Layer 3 Interface | Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface |
| DHCP Server | Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes
Support for DHCP options |
| DHCP relay at Layer 3 | Relays DHCP traffic across IP domains |
| RIP v2 | Support for Routing Information Protocol version 2 for dynamic routing |
| Hardware stack | Up to 8 units in a stack. Up to 400 ports managed as a single system with hardware failover |
| Security | |
| Secure Shell (SSH) Protocol | SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported |
| Web-based authentication | Web-based authentication provides network admission control through a web browser to any host devices and operating systems |
| STP Root Guard | This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes |
| RADIUS/TACACS+ | Supports RADIUS and TACACS authentication |
| ACLs | Support for up to 1K rules |
| DoS prevention | Denial-of-service (DOS) attack prevention |
| Storm control | Broadcast, multicast, and unknown unicast |
| Quality of Service | |
| Priority levels | 8 hardware queues |
| Port security | Ability to lock source MAC addresses to ports and limit the number of learned MAC addresses |
| Secure Copy (SCP) | Securely transfer files to and from the switch |
| Time-based port operation | Link up or down based on user-defined schedule (when the port is administratively up) |
| Power over Ethernet (PoE) | 802.3af PoE, 802.3at PoE+, or 60W PoE are delivered over the RJ-45 ports within the listed power budgets |
| Smartports | Simplified configuration of QoS and security capabilities |
| CPU | 1.3 GHz (dual-core) ARM for SX550 models
800 MHz (dual-core) ARM for all other models |
| weight | 3.09 kg (6.81 lb) |
| Packet buffer | 1.5 MB |
| Unit dimensions | 440 x 44 x 257 mm (17.3 x 1.7 x 10.12 in) |
