ipv6 verify source, reset ip source binding

Page 212 highlights

ipv6 verify source Use ipv6 verify source to enable the IPv6 source guard function. Use undo ipv6 verify source to restore the default. Syntax ipv6 verify source ip-address [ mac-address ] undo ipv6 verify source Default The IPv6 source guard function is disabled on an interface. Views Ethernet interface view, VLAN interface view Predefined user roles network-admin Parameters ip-address: Binds source IPv6 addresses to the interface. With this keyword specified, IP source guard filters packets received on the interface according to the source IPv6 addresses of the packets. mac-address: Binds source MAC addresses to the interface. With this keyword specified, IP source guard also checks the source MAC address of each packet received on the interface, and permits the packet only when both the source IPv6 and MAC addresses of the packet match a dynamic binding entry. Usage guidelines After you enable IPv6 source guard on an interface, IP source guard uses static IPv6 source guard binding entries to filter IPv6 packets received on the interface. If a packet matches an IP source guard binding entry, IP source guard forwards the packet. Otherwise, it drops the packet. You cannot enable dynamic IPv6 source guard on a service loopback interface. This command only enables IP source guard packet filtering on a port. The port uses static IPv6 source guard binding entries to filter packets without considering the keywords specified in the command.

ipv6 verify source
Use
ipv6 verify source
to enable the IPv6 source guard function.
Use
undo ipv6 verify source
to restore the default.
Syntax
ipv6 verify source ip-address
[
mac-address
]
undo ipv6 verify source
Default
The IPv6 source guard function is disabled on an interface.
Views
Ethernet interface view, VLAN interface view
Predefined user roles
network-admin
Parameters
ip-address
: Binds source IPv6 addresses to the interface. With this keyword specified, IP source guard
filters packets received on the interface according to the source IPv6 addresses of the packets.
mac-address
: Binds source MAC addresses to the interface. With this keyword specified, IP source guard
also checks the source MAC address of each packet received on the interface, and permits the packet
only when both the source IPv6 and MAC addresses of the packet match a dynamic binding entry.
Usage guidelines
After you enable IPv6 source guard on an interface, IP source guard uses static IPv6 source guard
binding entries to filter IPv6 packets received on the interface. If a packet matches an IP source guard
binding entry, IP source guard forwards the packet. Otherwise, it drops the packet.
You cannot enable dynamic IPv6 source guard on a service loopback interface.
This command only enables IP source guard packet filtering on a port. The port uses static IPv6 source
guard binding entries to filter packets without considering the keywords specified in the command.
Examples
# Enable IPv6 source guard on Ethernet port Ten-GigabitEthernet 1/1/5 to filter packets received on the
port.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/1/5
[Sysname-Ten-GigabitEthernet1/1/5] ipv6 verify source ip-address mac-address
Related commands
