"show ip flow top-talkers" output question

Unanswered Question

Hello all,

I have a question about the "show ip flow top-talkers" command. The top enry for this 1841 router with a T1 connection is always this line:

SrcIf            SrcIPaddress    DstIf         DstIPaddress    Pr SrcP   DstP  Bytes

Se0/1/0   Local    32 6EB0 306B  2366K

How do I get more information about this connection? I looked at ip protocol 32 and it says it is the MERIT Internodal Protocol. Also what does the bytes field mean? Is that bytes per second or per "flow"?

  protocol is 0x32 (in hex) = 50 (dec). This protocol is ESP. I assume, this flow is an IPSEC tunnel.

The endpoint is your device (regarding to dest interface = local). The "Bytes" field means number of

bytes in the flow. It is not releated to bytes/sec. Please, feel free to contact me if you need more


Kind regards,
