•
When UDP Relay is disabled for BOOTP/DHCP, the
ip helper
configuration is
not
retained and all
dependant functionality (i.e., automatic IP configuration for VLAN 1, Telnet and HTTP client authenti-
cation, etc.) is disrupted.
•
Up to three types of UDP Relay services are supported at any one time and in any combination.
Note.
If the relay service for BOOTP/DHCP is disabled when the switch reboots, the service is automati-
cally enabled when the switch comes back up. If there were three non-BOOTP/DHCP relay services
already enabled before the reboot, the most recent service enabled is disabled and replaced with the
BOOTP/DHCP relay service.
•
If port relay is enabled for the NBDD well-known port, NBNS is not automatically enabled by default.
Specify
NBNS/NBDD
to enable relay for both well-known ports.
•
Note that when UDP port relay is enabled for NTP, relay cannot forward NTP packets that contain a
destination IP address that matches a VLAN router IP address on the switch.
Examples
-> ip udp relay DNS
-> ip udp 3047 “Generic Service”
-> no ip udp relay BOOTP
-> no ip udp relay 3047
