| Model | Cisco-SG550X-48P-K9-EU |
| Switching Capacity (Gbps) | 176 |
| Performance | |
| Capacity in Millions of Packets per Second (mpps) (64-byte packets) | 130.94 |
| 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 |
| 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 | |

| 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 |
| 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 |
