DHCP Server and NAT Service on vSZ-D/SZ100-D/SZ144-D
The DHCP Server is designed in-line in the data plane and provides extreme scale in terms of IP address assignment to clients. This feature is especially useful in high density and dynamic deployments like stadiums, train stations where large number of clients continuously move in & out of WiFi coverage. The DHCP server in the network needs to scale to meet these challenging requirements. The DHCP server on the vSZ-D/SZ100-D/SZ144-D provides high scale IP assignment and management with minimal impact on forwarding latency. DHCP Server supports 63 pools with profile support.
With NAT service enabled, all the WiFi client traffic is NATed by vSZ-D/SZ100-D/SZ144-D before being forwarded to the core network. Each vSZ-D/SZ100-D/SZ144-D supports up to 16 public IP addresses for NAT. This feature essentially reduces the network overhead significantly since this reduces the MAC-table considerations on the UP-stream switches significantly. Again, very useful in high density deployments.
