PPPoed capture on PIX

I've looked all over the Cisco site to find out what this actual capture pppoed output I collected actually means. Any help? I can guess, I just need detail. Tried importing to ethereal with no luck.

Re: PPPoed capture on PIX

Just looks like ordinary network traffic to me. I don't see anything "pppoe" about that trace.

Re: PPPoed capture on PIX

Yes, I just want a decriptor for each thing. Not the IP's of course.

Re: PPPoed capture on PIX

Ok, I'll take a stab at it:

13:19:08.924970 - Really long timestamp

0002.b309.95cb 000e.a619.1502 - Source and destination mac addresses

0x0800 1434: - not sure

208.218.128.231.80 > - Source IP and port

10.145.10.203.1127: - Destination IP and port

. 2473143978:2473145358(1380) - MSS (Maximum Segment Size) I think

ack 3662812289 win 6930 - TCP ack # and window size

(DF) - "Do not fragment" bit is set

(ttl 62, id 63664) - Time to Live and some id #

HTH pls rate!
