subnet mask that you give to each pool. For example, if all pools were configured for a /24 mask, the total would be 40000/253 (approximately 158). If the subnet is increased, more pools can be configured. The maximum subnet that can be configured for a single pool is /17. The system displays an error message for configurations that exceed the allocated memory. • The switch supports 4K DHCP Snooping entries. • All platforms support Dynamic ARP Inspection on 16 VLANs per system. For more information, refer to Dynamic ARP Inspection. NOTE: If the DHCP server is on the top of rack (ToR) and the VLTi (ICL) is down due to a failed link, when a VLT node is rebooted in JumpStart mode, it is not able to reach the DHCP server, resulting in bare metal provisioning (BMP) failure. Configure the System to be a DHCP Server A DHCP server is a network device that has been programmed to provide network configuration parameters to clients upon request. Servers typically serve many clients, making host management much more organized and efficient. The following table lists the key responsibilities of DHCP servers. Table 25. DHCP Server Responsibilities DHCP Server Responsibility Address Storage and Management Configuration Parameter Storage and Management Lease Management Responding To Client Requests Providing Administration Services Description DHCP servers are the owners of the addresses used by DHCP clients. The server stores the addresses and manages their use, keeping track of which addresses have been allocated and which are still available. DHCP servers also store and maintain other parameters that are sent to clients when requested. These parameters specify in detail how a client is to operate. DHCP servers use leases to allocate addresses to clients for a limited time. The DHCP server maintains information about each of the leases, including lease length. DHCP servers respond to different types of requests from clients, primarily, granting, renewing, and terminating leases. DHCP servers include functionality that allows an administrator to implement policies that govern how DHCP performs its other tasks. NOTE: DHCP server is not supported on VLT.
