The M5300-52G ships as a Layer 2+ switch; this license unlocks full Layer 3 software, including dynamic routing, VRRP and multicast routing between VLANs. Netgear supplies it as an electronic SKU, with the license key delivered by email.\u003c\/p\u003e\n\u003ch2\u003eHow does the Netgear GSM7252L work?\u003c\/h2\u003e\n\u003cp\u003eThe license is applied to an installed GSM7252S, a 48-port Gigabit switch with 4 shared SFP ports and 2 built-in 10GBASE-T\/SFP+ combo ports. With the license in place, Netgear lists Layer 3 features including RIP, OSPF and OSPFv3, VRRP, ECMP, IPv6 routing, PIM-SM, PIM-DM, DVMRP, IGMP and MLD proxy, multicast routing between subnets and VLANs, and a DHCP IPv4\/IPv6 server.\u003c\/p\u003e\n\u003cp\u003eIn an M5300 stack, the Stack Master decides the software package. A Layer 2+ master with its Layer 3 license runs Layer 3 software across the whole stack, so other members can stay Layer 2+. Netgear recommends a second Layer 3 unit as Secondary Master; otherwise a master failure drops the stack back to Layer 2+.\u003c\/p\u003e\n\u003cp\u003eFor this reason, multicast-heavy AV networks often license both the master and the secondary master.
