This new script is for Network Engineers and System Engineers a like. Though I must admit it is more for the System Engineers who do not have access to the command line on the CDP enabled device. Have you ever wanted to know what CDP enabled devces ( and info related to those devices ) that were directly connected to your your Core Switch? But you just do not have the access to get that info. But you do have access to the monitoring system, which has SNMP access to the Core Switch.
Well this is where my script comes into play... Stay tuned for updates, as I'm planning on adding to this script. So you can run it with the detail option and a detail port option. Please post any support related question in the forums here..http://www.linuxdynasty.org/forums/Scripting/scripting/sh_cdp_neighbor_help
Revision 1.2 9/13/2009

Revision 1.1 9/11/2009
- Added –type option ( –type=detail )
Revision 1.0 9/10/2009
- This script is the equivalent of sho cdp nei on a cisco switch, but this is using snmp.
When you log into a switch and run a show cdp neighbor, your info might look a little like this.. show cdp neighborCapability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone Device ID Local Intrfce Holdtme Capability Platform Port ID71_5th_SW1 Gig 10/15 145 S I WS-C2960G-Gig 0/48D_M1001_V180_SW1 Gig 1/42 132 S I WS-C2960G-Gig 0/1D_M1001_V181_SW1 Gig 1/46 136 S I WS-C2960G-Gig 0/1D_M1001_V181_SW2 Gig 1/47 166 S I WS-C2960G-Gig 0/1D_M1001_V180_SW3 Gig 1/43 147 S I WS-C2960G-Gig 0/1D_M1001_V181_SW3 Gig 1/48 158 S I WS-C2960G-Gig 0/1D_M1001_V180_SW2 Gig 1/41 141 S I WS-C2960G-Gig 0/1D_M1001_V181_SW4 Gig 1/44 179 S I WS-C2960G-Gig 0/1D_M1001_V180_SW4 Gig 1/40 145 S I WS-C3560G-Gig 0/1D_M701_V177_SW4 Gig 10/7 174 S I WS-C2970G-Gig 0/25D_M701_V177_SW1 Gig 10/6 154 S I WS-C2970G-Gig 0/25Router Gig 10/1 162 R S WS-C6513 Gig 9/9Router1 Gig 10/14 168 R S WS-C6513 Gig 9/1679_18th_Fl_SW1 Gig 10/12 174 S I WS-C2960G-Gig 0/48D_1700_V187_SW1 Gig 10/13 129 S I WS-C3560G-Gig 0/28D_1700_V187_SW3 Gig 10/10 146 S I WS-C2960G-Gig 0/48D_1700_V187_SW2 Gig 10/9 148 S I WS-C2960G-Gig 0/48D_522_V176_SW1 Gig 10/3 121 S I WS-C2970G-Gig 0/25D_522_V176_SW4 Gig 10/4 125 S I WS-C2970G-Gig 0/25D_CL001_V200_SW1 Gig 10/11 125 S I WS-C2960G-Gig 0/242W_4507R Gig 7/2 147 R S I WS-C4507R Gig 3/9Now this is how it will look if you run sh_cdp_neighbor.py script…
