Field Description
Next Hop Mac
Address
In this screen Next Hop Mac Address displayed is in fact the resulting Mac
Address of the ARP process for the destination IP address.
N/A: Indicates that a cross connection was made and this field is irrelevant.
FFFFFFFF:
Indicates an unreachable bundle.
Connectivity Status
Disabled:
Channel is disabled.
OK:
Indicates that Ethernet frames are received on the local and
remote IPmux-16.
OK-LOOP:
Indicates that a cross connection has been successfully made.
Remote Fail: Ethernet frames are not received by the remote IPmux-16.
Local Fail:
Ethernet frames are not received by the local IPmux-16.
Disabled:
Connection is disabled.
Sequence Errors
The number of times a frame was dropped because frames were received from
the network with SN field not equal to the last SN + 1. This indicates a packet
loss or a certain level of packet misordering.
Jitter Buffer
Underflows
The number of times frames were dropped because the receive buffer was in an
underflow state. The buffer enters underflow state when:
• Recurring or numerous sequence errors occur
• Underflow takes place due to PDV expiration
• An overflow condition occurs.
Jitter Buffer Overflows Number of times that frames were dropped because the receive buffer exceeded
the maximum allowed depth.
For internal cross-connected bundles, the Next Hop MAC Address will be set to
N/A, and the Connectivity Status will be OK – Loop to the cross-connected bundle.
