These parameters are displayed:
• Hops – The number hops taken to reach the target MEP.
• MA – Maintenance association name.
• IP/Alias – IP address or DNS alias of the target device’s CPU.

forwarded if received by the target MEP.
• Ingress MAC Address – MAC address of the ingress port on the target device.
• Egress MAC Address – MAC address of the egress port on the target device.
• Ingress Action – Action taken on the ingress port:
• IngOk – The target data frame passed through to the MAC Relay Entity.
• IngDown – The bridge port’s MAC_Operational parameter is false. This value could be
returned, for example, by an operationally Down MEP that has another Down MEP at a
higher MD level on the same bridge port that is causing the bridge port’s MAC_Operational
parameter to be false.
