Stránky produktu: CBS220-24T-4G Quick start guide: Quick start guide Switching capacity Forwarding rate in millions of packets per second (mpps; 64-byte packets) – 41,66 Layer 2 switching Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) – Protocols for automatically propagating and configuring VLANs in a bridged domain Security QoS Multicast Internet Group Management Protocol (IGMP) Versions 1, 2, and 3 Snooping – IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups Standards IPv6 Management Discovery Link Layer Discovery Protocol (LLDP) (802.1ab) with LLDP-MED Extensions – LLDP allows the switch to advertise its identification, configuration, and capabilities to neighboring devices that store the data in a MIB. LLDP-MED is an enhancement to LLDP that adds the extensions needed for IP phones.
