Syntax

undo ip source static binding ip-address ip-address
View
Ethernet port view
Parameters
ip-address ip-address: Specifies the IP address to be statically bound.
mac-address mac-address: Specifies the MAC address to be statically bound.
Description
Use the ip source static binding ip-address command to configure the static binding among source
IP address, source MAC address, and the port number so as to generate static binding entries.
Use the undo ip source static binding ip-address command to remove the static binding among
source IP address, source MAC address, and the port.
By default, no binding among source IP address, source MAC address, and the port number is
configured.
To create a static binding after IP filtering is enabled with the mac-address keyword included on a port,
the mac-address argument must be specified; otherwise, the packets sent from this IP address cannot
pass the IP filtering.
Related commands: ip check source ip-address.
Examples
# Configure static binding among source IP address 1.1.1.1, source MAC address 0015-e20f-0101,
and Ethernet 1/0/3.
