You can use the set dhcpd_recv_sock_buf_size command to tune the DHCP receive socket buffer memory. The DHCP receive socket buffer holds DHCP packets that are queued on the UDP (User Datagram Protocol) port from the NIC (Network Interface Controller). This command is useful when you want to increase the DHCP receive buffer size to accommodate occasional burst traffic and high volume DHCP requests. Use the show dhcpd_recv_sock_buf_size to view the current buffer size.

Note

Ensure that you use this command only when you are dealing with burst traffic situations in high volume deployments.

Syntax

set dhcpd_recv_sock_buf_size N [120 <= N <= 8192, 1536=default]

Examples

Argument	Description
