Packet
Type Feature
Description
Filtered Boot Packets are filtered while booting.
Flow Descriptor
• Packets are Filtered due to a Multicast packet classified as
UNICAST packet.
• Packets are filtered due to offline modem receiving packet from
WAN port.
Unknown Reason Code Packets dropping due to reasons not listed here.
Flow Correlator
Packet are filtered due to improper establishing SAT-to-SAT traffic
(This counter generally is seen on outbounding Hub modem in point-
to-multipoint setup)
Management Path Not used.
Wan scaling
Internal Error occurred during WAN scaling sub process in processing
packet.
Ping Ping packets were received but PING feature was Disabled.
Access Control
Packets are received while “Access List” control is Enabled but IP
address does not match the access list database.
Vipersat MCP
Internal Error occurred while processing Vipersat Multi-command
messages.
Vipersat UCP
Internal Error occurred while processing Vipersat Uni-command
messages.
Codeload Internal error occurred while processing Codeload messages.
Multicast A Multicast packet is received but no application is associated with it.
Bad Packet
Malformed packet is received. This may be due to internal or external
error
Route
Applies to Vipersat Remote only – when a packet is received from the
WAN and the Route Table contains a route to transmit that packet to
the WAN, the packet is filtered to prevent a routing loop.
Vipersat Remote
Packets are filtered due to Vipersat Remote mode (a modem
configured as a Vipersat Remote Expansion unit and default route set
to 0.0.0.0/0).
QoS Rule Packet filtered due to QoS Rule configured to filter.
Vipersat Loop Packets are filtered due to WAN loop in Vipersat Remote mode
Bad Header Len Filtered due to packets received with less than 14 bytes of L2 header.
Bad Data Ptr Internal error occurred while accessing the packet data.
MAC Split Err Not currently used.
L3Type Err Not currently used.
Local Destination
Packet received with destination MAC as modem MAC and destination
IP is not modem IP while modem is operating in bridge mode
(Managed Switch)
Redundancy Err
Applies to Offline modem in 1:1 Redundancy
Packets are received on the WAN port by the both Offline unit and
Online unit, only Online unit is allowed to forward the packets.
Indicates packets received by Offline unit from WAN port that were
filtered because unit is Offline.
ICMP Filter
This is the same as “Filtered Ping”, except this will update in Managed
Switch mode.
Port Err
Non-IP or ARP packets are targeted to End-station. (End-station will
not allow any non-Packets).
