Configuring VXLAN Tunneling
– 499 –
vxlan udp-dst-port This command configures the VXLAN UDP destination port. Use the no form to
restore the default setting.
Syntax
vxlan udp-dst-port udp-port
no vxlan udp-dst-port
udp-port - UDP port used for the VXLAN destination port.
Default Setting
4789
Command Mode
Global Configuration
Command Usage
The VXLAN header inserts a VNI at the beginning of the packet along with the IP
header and UDP header. The UDP port defined by this command is used in the
outer UDP header.
The outer UDP header includes a source port provided by the VTEP and the
destination port being a well-known UDP port. IANA
10
has assigned the value 4789
for the VXLAN UDP port. This value should be used by default as the destination
UDP port. Some early implementations of VXLAN have used other values for the
destination port. This command is therefore provided to enable interoperability
with these implementations.
Example
Console(config)#vxlan udp-dst-port 4933
Console(config)#end
Console#show vxlan udp-dst-port
VXLAN UDP Destination Port: 4933
Console#
