Counts the packets received with IP header length are less than 20 bytes OR IPV4
version is NOT 4. Applies in non-switch mode only.
This counter updates if the ingress packet total length (PACKET_SIZE) less than the
Ethernet header size (if present, only from LAN and END station) and total length in
IPV4 total length filed. Applies in non-switch mode only.
This counter updates if the IPV4 packet received with TTL zero and need to be
forwarded. Applies in non-switch mode only.
Counts the packets received with IPV4_DEST_ADDR has no match in Route Table.
Applies in non-switch mode only.
This counter updates if total length filed in IPV4 header is less than 20 bytes OR
PACKET_SIZE is less than 20. Applies in non-switch mode only.
If incoming packet has Ethernet type was not IPV4, IPv6, ARP, PPP_SESSION, or
PPP_DISCOVERY and non-switch mode. It accepts all the Ethernet types in switch
mode.
Counts the packets received with bad IPV4 header checksum. Applies in non-switch
mode only.
This counter updates if the IPV4 destination address is either 255.255.255.255, or
0.X.X.X, or 127.X.X.X, or (224-255).X.X.X. Applies in non-switch mode only.
Non-Switch mode: This counter updates if the Ingress packet cannot traverse within
the ME components due to resources scarcity.
Switch mode: This counter updates if a) the ingresses packet destination MAC
address is NP's MAC but the IP address is NOT the NP's IP, or b) if the ingress
packet cannot traverse within the MEs components due to internal resources scarcity.
This is the total packets destined to the NP Interface.
This is the total packets forwarded by router.
This is the number of packets delivered to management applications running on
the NP Interface.
This is the number of IP fragments created by the NP Interface because the packet
being sent exceeds the maximum transmit unit (MTU).
