Open	This counter shows the number of partially filled packets which have some flow data but are not yet filled or have been timed out (60 seconds maximum).
Error	This counter increments when there was an error during exporting of the collector packet. The most common reason will be a UDP unreachable destination for the configured collector.
Overflow events	The number of times the active cache overflowed.

Syntax 

top-protocols

Context 

tools>dump>cflowd [clear]

Description 

This command displays the summary information for the top 20 protocol traffic seen in the cflowd cache. All statistics are calculated based on the data collected since the last clearing of the cflowd stats with clear keyword for this command.

If the clear optional keyword is given, then the top-flows are displayed, and then this cache is cleared.

Protocol ID	Displays the IPv4 or IPv6 protocol type. This will either print the well known protocol name or the decimal protocol number.
Total Flows	Displays the total number of flows recorded since the last clearing of cflowd statistics with this protocol type.
Flows/Sec	Displays the average number of flows detected for the associated protocol type. (Total flows / number of seconds since last clear)
Packets/Flow	Displays the average number of packets per flow. (Total number of packets / total flows)
Bytes/Pkts	Displays the average number of bytes per packet for the associated protocol type. (Total number of bytes for the associated protocol / total number of packets seen for the associated protocol)
Packets/Sec	Displays the average number of packets seen for the associated protocol type. (Number of packets / time since last clear)

S-Port Src Port	Displays the source protocol port number.
Msk	Displays the route prefix length for route to source IP address.
AS	Displays the Autonomous Systems number for the source route (the AS is either originating AS or peer AS depending on cflowd configuration).
D-Port Dst Port	DIsplays the destination protocol port number.
Msk	Displays the route prefix length for route to destination IP address (Forwarding route).
AS	Displays the Autonomous Systems number for the destination route (the AS is either originating AS or peer AS depending on cflowd configuration)

packet-size

Syntax 

packet-size [ipv4 | ipv6] [clear]

Context 

tools>dump>cflowd

Description 

This command displays packet size distribution for sampled IP traffic. Values are displays in decimal format (1.0 = 100%, .500 = 50%). Separate statistics are maintained and shown for IPv4 and IPv6 traffic.

Sample Output

SR-12# tools dump cflowd packet-size ipv4

 IP packet size distribution (801600 total packets):

   1-32   64   96  128  160  192  224  256  288  320  352  384  416  448  480

Clear Commands

cflowd

Syntax 

cflowd

Context 

clear

Description 

Clears the raw and aggregation flow caches which are sending flow data to the configured collectors. This action will trigger all the flows to be discarded. The cache restarts flow data collection from a fresh state. This command also clears global stats collector stats listed in the cflowd show commands.
