Usage Information

The following describes the show ip traffic summary shown in the following example.

Keyword

Definition

unknown protocol...

No receiver for these packets. Counts packets whose protocol type field is not recognized by Dell EMC Networking OS.

not a gateway...

Packets can not be routed; the host/network is unreachable.

security failures...

Counts the number of received unicast/multicast packets that could not be forwarded due to:

route not found for unicast/multicast; ingress interfaces do not belong to the destination multicast group
destination IP address belongs to reserved prefixes; the host/network is unreachable

bad options...

Unrecognized IP option on a received packet.

Frags:

IP fragments received.

... reassembled

Number of IP fragments that were reassembled.

... timeouts

Number of times a timer expired on a reassembled queue.

... too big

Number of invalid IP fragments received.

... couldn’t fragment

Number of packets that could not be fragmented and forwarded.

...encapsulation failed

Counts packets which could not be forwarded due to ARP resolution failure. Dell EMC Networking OS sends an arp request prior to forwarding an IP packet. If a reply is not received, Dell EMC Networking OS repeats the request three times. These packets are counted in encapsulation failed.

Rcvd:

...short packets

The number of bytes in the packet are too small.

...bad length

The length of the packet was not correct.

...no port broadcasts

The incoming broadcast/multicast packet did not have any listener.

...socket full

The applications buffer is full and the incoming packet are dropped.

The Dell Monitoring MIB provides access to the following statistics.
