Grandstream [recently launched their GWN7721 Series](https://blog.grandstream.com/press-releases/grandstream-announces-layer-2-lite-managed-2.5-gigabit-network-switches?utm_campaign=New%20Product%20Launch&utm_medium=email&_hsenc=p2ANqtz-_G_zk4K8pSKWiiIgSDJFMMMMt38pIL2opvzM0Z7curRzihVqLrz3ofRJEs_lkNkjqn0eBFaOa9273YW3rwgupESBTCSw&_hsmi=374680481&utm_content=374686779&utm_source=hs_email). Grandstream's GWN7721 and GWN7721P are Layer 2 Lite managed switches with support for multigigabit Ethernet, designed for small to medium-sized network environments. Both models offer eight 2.5 GbE RJ‑45 ports and two 10 Gbps SFP+ uplink ports, allowing for faster local network speeds and high-bandwidth uplinks to core switches or servers, and are now available at Streakwave.

The key difference between the two models is that the GWN7721P supports Power over Ethernet (PoE/PoE+), with up to 30 W per port and a total power budget of 130 W. This makes it suitable for powering devices like IP phones, access points, and cameras directly through the Ethernet cable.

## **Network Features**

These switches include several features useful for managing network traffic and segmenting devices:

- **VLAN support** (including port-based and 802.1Q tagging) allows network administrators to separate traffic into logical groups.
- **Quality of Service (QoS)** features prioritize traffic types (e.g., voice or video) using DSCP or 802.1p markings.
- **IGMP Snooping** helps manage multicast traffic efficiently, which is useful for streaming or IPTV applications.
- **Bandwidth control** is supported on a per-port basis, allowing limits to be set for certain devices or applications.

## **Management and Monitoring**

Users can manage the GWN7721 series using several methods:

- A built-in web interface accessible via browser.
- **GWN Manager**: Grandstream’s free on-premise management software.
- **GDMS Networking**: Grandstream’s free cloud-based platform.

For diagnostics and monitoring, the switches support features like:

- **Port mirroring** for traffic inspection.
- **Loop detection** and **cable testing** to identify physical layer issues.
- **SNMPv2**, **DHCP snooping**, and **Spanning Tree Protocol (STP/RSTP)** for broader network control and visibility.

 

## **Use Cases**

These switches are appropriate for:

- SMB networks requiring multigigabit throughput.
- Environments with PoE devices.
- Educational settings or labs focused on network configuration and testing.
