444
ping mac port
ping mac <mac> port <port> {domain} <domain_name> {association}
<association_name>
Description
Allows you to ping on the Layer 2 level throughout the specified domain and MA. The ping, or
loopback message (LBM), goes from the MEP configured on the port toward the given MAC address.
Syntax Description
Default
N/A.
Usage Guidelines
You must have CFM parameters configured prior to issuing a Layer 2 ping.
In order to send a Layer 2 ping, you must specify the port (MEP), the domain, and the MA from which
you are issuing the ping. An inward-facing MEP sends the ping to all ports (except the sending port) on
the VLAN that is assigned to the specified MA, and an outward-facing MEP sends the ping out from
that port from that MA toward the specified MAC address.
All MIPs along the way forward the LBM to the destination. The destination MP responds back to the
originator with a loopback reply (LBR).
This command sends out a ping from the MEP configured on the specified port toward the specified
MAC address. If you attempt to send a ping message from a port that is not configured as a MEP, the
system returns an error message. If the specified port is configured as both an inward-facing and an
outward-facing MEP, the Layer 2 forwarding table decides which to use. If the specified MAC address is
not present in the Layer 2 forwarding table (FDB), the system cannot send the ping.
Example
The following command sends a Layer 2 ping to the unique system MAC address 00:04:96:1F:A4:31
from the previously configured inward-facing MEP (port 2:4) in the speed association in the atlanta
domain:
ping mac 00:04:96:1F:A4:31 port 2:4 atlanta speed
mac
Enter the unique system MAC address on the device you want to reach. Enter
this value in the format XX:XX:XX:XX:XX:XX.
port
Enter the port number of the MEP from which you are issuing the ping.
domain
Enter this keyword.
domain_name
Enter the name of the domain from which you are issuing the ping.
association
Enter this keyword.
association_name
Enter the name of the association from which you are issuing the ping.
