Can someone help me with a perl script to do the following task:
I have output from cdp neigh det from a buch of cisco routers that looks like this:
router1#sh cdp neigh det

This is a short sample but my file will end up with 1000's of entries like this. What I am trying to do
is this:
Parse the file line by line.
Look for Device ID:
Copy text in Device ID after the : to the newline into a new file appended with a comma
continue down the file looking for address: and copy the value after the : and before the newline into
the file wher the device id went on the same line with the associated device with an appened comma.
continue down the file and search for Platform: and copy the value between the : and newline to the file
from above after the IP address
Basically I am trying to end up with a comma delimted file. If the above data was run through my
theoretical script it would lookslike this:
myrouter, 10.1.1.1, WS-C6509, Capabilities: Trans-Bridge Switch
myrouter, 10.1.1.1, WS-C6509, Capabilities: Trans-Bridge Switch
myrouter, 10.1.1.1, WS-C6509, Capabilities: Trans-Bridge Switch
johnsrouter, 10.2.2.2, cisco WS-C6506, Capabilities: Router Switch
bobsrouter, 10.3.3.3, WS-C6509, Capabilities: Trans-Bridge Switch
Caveats:
once a device ID is found in the line by line only and ip address and platform within 15 lines should be
used for creating that record. The reason for this is I may end up getting back cdp information that is
non consistent. if this caveat is not in place it could throw off all record below the incomplete one.
sometimes there will be multiple IP address on seperate lines. These should all be placed in the same
record.
The output for IP address is inconsistent. sometimes it is IP address: and sometimes address: Need to
accomadate both
capital letters in the the search need to be irrelevant
here is an example of what a record with multiple ips would look like:
Port (Our Port): 2/5
Device-ID: testbed
Device Addresses:
IP Address: 172.16.0.3
IP Address: 172.16.0.3
Holdtime: 126 sec
Capabilities: TRANSPARENT_BRIDGE SWITCH

Platform: cisco WS-C3548-XL
Port-ID (Port on Neighbors's Device): GigabitEthernet0/8
VTP Management Domain: EXP
Native VLAN: unknown
Duplex: full
This would be an example of an alternate format I need to account for:
wonky# sh cdp neigh det
CDP neigbors information
Port : 25
Device ID : wonky1
Address Type : IP Address : 192.168.1.1
Platform : HP 8000M
Capability : S
Device Port : D2
Version : Revision C.09.28 /sw/code/build/vgro(c09)
wonky#
I would creatley appreciate any help that anyone can provide with scripting his up.
