I am troubleshooting dhcp failure between my cisco wireless phones and my call manager server. Cisco tech support has asked me to get a sniffer capture at my access point and dhcp server to verify packets are being passed between. He pointed me to Wireshark to use for the capture.
Because the Cisco techs usually speak two or three levels above me and I can't get them to come down, i'm hoping someone here can point me in the right direction to get the right capture.
i've installed wireshark to my pc but when i run a capture (wide open) i don't see any traffic bound for any of my voice network. (i have statically assigned the ip of the pc to the voice network).
