Syntax

content_copy zoom_out_map
show mac-vrf forwarding instance
<brief|detail|extensive>
<vlan-name vlan name>

Description

Display the MAC-IP addresses for all IPv4 (ARP) and IPv6 (ND) bindings for VLANs in routing instances where the instance type is MAC-VRF.

Note:

We've implemented the show mac-vrf commands on all supported platforms. If a particular platform doesn't support a specific sub-command or option, when you run the command, the output is empty. For example, show mac-vrf forwarding age is available only on MX Series platforms. If you run that command on any other supported platform, the output is empty.

Options

none Display the brief listing of MAC-IP addresses for all IPv4 (ARP) and IPv6 (ND) bindings for VLANs in routing instances where the instance type is MAC-VRF.
brief | detail | extensive

(Optional) Display the specified level of output.

vlan-name vlan-name

(Optional) Display information about the specified VLAN only.

Additional Information

On MX Series routers and the EX9200 line of switches, this command hierarchy is an alias for the show l2-learning instance command hierarchy.

On QFX Series switches, this command hierarchy is an alias for the show ethernet-switching instance command hierarchy.
