21-8 config dhcp_relay option_61 add
Description
This command adds a rule to determine the relay server based on Option 61. The match rule can be
based on either MAC address or a user-specified string. Only one relay server can be specified for a
MAC address or a string. If relay servers are determined based on Option 60, and one relay server is
determined based on Option 61, the final relay servers will be the union of these two sets of the
servers.
