CDP

Figure 10-16. Example of CDP Neighbor Data in a Switch 2650 or 6108MIB

For the current Switch 2650 or 6108 MIB, go to the HP Procurve World Wide

Web site at:

http://ww.hp.com/go/hpprocurve

Click on software, then MIBs.

Operating Notes

Neighbor Maximum. The Switches 2650 and 6108 support up to 60 entries

(neighbors) in the CDP Neighbors table. Remember that multiple CDP devices

can be neighbors on the same port if they are connected to the switch through

a non-CDP device.

CDP Version Data. The Switches 2650 and 6108 use CDP-V1, but do not

include IP prefix information, which is a router function; not a switch appli-

cation.

Port Trunking with CDP. Where a static or LACP trunk forms the link

between the switch and another CDP device, only one physical link in the

trunk is used to transmit outbound CDP packets.

The first number after the MIB string is the switch port on

which the data point for that entry was received. In this

case, the switch CDP packets on ports A1 and A3. (For CDP

purposes, port numbering is consecutive, from 1 to n,

where n is the last consecutive port on the switch.)

CDP MIB data is

grouped by type.

That is, the

Address Types

for all detected

CDP devices are

listed first, then

the IP

addresses of the

source devices,

and so on.
