Forwarding engine

●  WS-X6816-10G-2T: comes equipped with DFC4 for distributed forwarding, supporting 256K forwarding entries, increased ACL entries to 64K, increased Netflow entries to 512K and increased IPv4 forwarding speed to 60 Mpps

●  WS-X6816-10G-2TXL: equipped with DFC4XL for distributed forwarding, supporting 1 million forwarding entries, increased ACL entries to 256K, increased Netflow entries to 1024K and increased IPv4 forwarding speed to 60 Mpps

●  Increased performance of up to 60Mpps for L2, IPv4 and MPLS forwarding and up to 30Mpps for IPv6 forwarding

●  Support for 16K Bridge Domains, allowing the standard 4K VLANs to be reused across these bridge domains, effectively increasing the number of VLANs available in the system

●  Increased MAC Address Table to 128K

●  Increased multicast routes to 256K

●  IGMPv3 snooping in hardware

●  PIM registers in hardware

●  IPv6 MLDv2 snooping in hardware

●  IPV4 & IPv6 in IPv6 tunnelling

●  IPv6 in IPv4 tunneling ISATAP, 6to4, GRE)

●  QoS support for uniform, short pipe and pipe mode tunnel

●  Terminate the tunnel in the same loopback
