                                    mac <MAC-ADDR> | vlan <VLAN-ID>] |
                           interface <IFNAME>] [vsx-peer]

Description

Shows summary or detailed IPv4 source lockdown information. When entered without parameters, summary status information for all interfaces (ports) in the binding database is shown.

Command context

Parameters

binding: Specifies that detailed lockdown binding record information is to be displayed. The binding database record can be identified by any one of interface (port), ip, mac, or vlan.
interface <IFNAME>: Specifies the client interface (port). When entered without the binding parameter, the summary status information is displayed for the specified interface.
ip <IPV4-ADDR>: Specifies the client IPv4 unicast address.
mac <MAC-ADDR>: Specifies the client MAC address.
vlan <VLAN-ID>: Specifies the ID of an existing VLAN on which the client is connected. Range: 1 to 4094.
[vsx-peer]: Shows the output from the VSX peer switch. If the switches do not have the VSX configuration or the ISL is down, the output from the VSX peer switch is not displayed. This parameter is available on switches that support VSX.

Authority
