Huawei Switch S3300 supports the enhanced and flexible QinQ function. This function does not occupy ACL resources. The S3300 can map the CoS value of the inner VLAN to the outer VLAN or modify the CoS value of the outer VLAN. The QoS class can be flexibly marked according to service requirements to meet the requirements of multi-service bearer.
The S3300 supports 1K multicast groups, supports controllable multicast, and supports IGMP Snooping/Filter/Fast Leave/Proxy. The S3300 supports the inter-VLAN multicast replication function of the line rate. It supports the multicast load balancing of bundled ports and supports the Vlan-based multicast call admission control function (multicast CAC) to fully meet the IPTV operation requirements. The S3300 supports the MCE function to isolate different VPN users on the same device, effectively solve user data security problems, and reduce user investment costs.
