Thanks for the reply Steve,
I was able to run a packet capture and write to a file which gave me what I was looking for.
packet-capture {
file filename mypacketcapture files 2 size 50000000;
maximum-capture-size 1500;
ge-0/0/0 {
description to-Comcast;
unit 0 {
family inet {
dhcp-client;
filter {
input PCAP;
output PCAP;
}
}
