Technical Specification
| Layer | Layer 2, 3 Switching |
| Layer 2 Switching | |
| Spanning Tree Protocol | Standard 802.1d Spanning Tree support Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default |
| 8 instances are supported Multiple Spanning Tree instances using 802.1s (MSTP | |
| Port grouping | 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 | Support for up to 4096 VLANs simultaneously Port-based and 802.1Q tag-based VLANs MAC-based VLAN |
| Management VLAN Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks | |
| Guest VLAN Unauthenticated VLAN Dynamic VLAN assignment via RADIUS server along with 802.1x client | |
| authentication CPE VLAN | |
| Voice VLAN | Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. |
| Auto voice capabilities deliver networkwide zero-touch deployment of voice endpoints and call control devices | |
| Multicast TV VLAN | Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in |
| separate VLANs (also known as MVR) | |
| Q-in-Q VLAN | VLANs transparently cross a service provider network while isolating traffic among customers |
| Generic VLAN Registration Protocol | Protocols for automatically propagating and configuring VLANs in a bridged domain |
| Unidirectional Link Detection (UDLD) | UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or cable/port faults |
| to prevent forwarding loops and blackholing of traffic in switched networks | |
| Dynamic Host Configuration Protocol | Relay of DHCP traffic to DHCP server in different VLAN; works with DHCP Option 82 |
| Internet Group Management Protocol | IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 1K multicast groups (source- |
| specific multicasting is also supported) | |
| IGMP Querier | IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast |
| router | |
| Head-of-line (HOL) blocking | HOL blocking prevention |
| Jumbo frames | Up to 9K (9216) bytes |
| Layer 3 | |
| IPv4 routing | Wirespeed routing of IPv4 packets |
| Up to 512 static routes and up to 128 IP interfaces | |
| Classless Interdomain Routing (CIDR) | Support for CIDR |
| Layer 3 Interface | Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface |
| DHCP relay at Layer 3 | Relay of DHCP traffic across IP domains |
| User Datagram Protocol (UDP) relay | Relay of broadcast information across Layer 3 domains for application discovery or relaying of bootP/DHCP |
| packets | |
| DHCP Server | Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes |
| Support for DHCP options | |
| Cabling type | Unshielded twisted pair (UTP) Category 5 or better for 10BASE-T/100BASE-TX; UTP Category 5 |
| Ethernet or better for 1000BASE-T | |
| LEDs | System, Link/Act, PoE, Speed, LED power saving option |
| Flash | 32 MB |
| CPU memory | 256 MB |
